The BSLCDBC is a clean solution for eliminating expensive gauges (Boost gauges alone can cost more than the BSLCDBC, especially if you have to have someone install the gauge inside.) Outside of reinventing what BlackStealth has done and setting up an LCD to display the data realtime from the flash ECU, setting up a car pc which you say is extremely difficult, or having a laptop sitting on the passenger seat, how does the flash ECU replace the gauge functionality of the BSLCDBC?
    Hmm, I guess I wasn't clear enough; that would explain why every post after mine was, "I can't see why anyone would get rid of the BSLCDBC," even though I dedicated an entire paragraph to why people would do exactly that. That or more likely people simply don't read my posts, and just simply post their thoughts. I mean it was like three paragraphs, you could be watching pr0n or something far more enlightening... Before I begin here, let me make something completely and utterly clear:

    Everything written here is my opinion, you may or may not agree with what I say, and that's perfectly fine. Also, the BlackStealth LCD Boost Controller is freaking awesome! If you're doing any tuning/modifications to your car and don't have a flashable ECU, you should have one of these in your car! BlackStealth rocks and is an awesome guy for making this product for our platform! If you have a pocket full of cash and nothing to spend it on, the BSLCDBC is never a bad choice. I plan to run one in my Talon; mostly because flash-tuning improvements for DSMs are completely dead and I want boost control, and partially because the BSLCDBC is straight baller!

    Ehem. That said, I'll get to your question: First and foremost the Op asked:

Does it not mesh well with the flash ecu for whatever reason?
    I directly answered his question as to why this would be; those reasons are mainly based on functionality overlap as you noted, which I feel I outlined quite well in my original post.

    Well, when you remove every other option to display data, the BSLCDBC sounds like the best/only option no? However my post was not designed to say the flash ECU replaced the BSLCDBC's ability to display data per se, merely that with the flash ECU the additional data display isn't needed. The things you need to see can be displayed by traditional gauges and the flash ECU, imho not only sufficiently, but generally better than the BSLCDBC. For displaying the things you don't really need to see, but want to see, a carpc is the best choice, followed by your laptop in the passenger set, and then followed by the BSLCDBC. Recognize though that is ranked based on usability, and data acquisition, not convenience. As for why to use traditional gauges with a flash ECU instead of the BSLCDBC, well that's a bit more involved. Don't worry though, you know I love to write novels (this post is at the text limit), so tighten your boot-straps and get ready to dive into the rabbit hole.

    First, what boost gauge are you running that costs more than the BSLCDBC!? Last time I inquired about the BSLCDBC, it had a going price of almost $300, so unless prices have dropped dramatically you're buying one hardcore boost gauge! (remember we're only talking display here, not boost control) I mean you could just roll into Advance/Autozone and snag a boost gauge for less than $20; will it be the most accurate, badass, light-up, blinking gauge you'll ever own: no. Will it give you a reasonably accurate boost reading: yes. Now that may sound blasphemous, but recognize that boost (psi) is a varying/inexact tool for measuring airflow (which is what we care about). When you tune via a flash ECU, you'll be tuning by load, not by boost for that exact reason. A boost gauge is really only useful for seeing sudden changes in pressure, i.e. problems. As for the install; you can pick up an a-pillar gauge pod for less than $50 in the classifieds, and if you can't install a boost gauge (there's only like 10 step-by-step guides on these forums) then you certainly aren't going to be tuning, let alone installing/needing a BSLCDBC...

    So more onto the display situation; say you want to display your AFR on your BSLCDBC, fine and dandy it can do that... Well, if you already have a wideband that outputs a 0-5v signal for it to convert. You've probably noticed that nowadays most widebands have everything built directly into the gauge too. So riddle me this, if you have to have a wideband for the output anyway, what are you gonna do, just stuff the WB gauge under the dash? Maybe I'm crazy, but I think a nice big led sweeping display with AFR displayed in the center is much nicer and easier to read than a 1 inch tall display on my dash... In fact that's probably my biggest beef on this whole deal! Gauges are typically analog, with large easy to read sweeping displays; which to me is much nicer than trying to read a little screen.

    So what about the stuff traditional gauges can't display then? Knock sum and such. Well as outlined in my original post the flash ECU can display knock via flashing the CEL, with any set value you'd like. Does this give you actual knock count: no. Does it really matter: not particularly. (though Ceddy used the DSM boost gauge to show knock count, it wouldn't surprise me if Greg has already implemented this for our platform as well) Sure seeing the actual number sounds good, however unless you're rocking a photographic memory, and can instantly look down and remember RPM/Load/Knock Count/Timing, knowing exactly how much knock you have isn't really very useful. Since the BSLCDBC doesn't currently support datalogging, both the CEL flash and the red flash of the BSLCDBC are equivalently good at saying "take your foot off the gas stupid!"

    Okay then, what about the other stuff like IDC/voltage/fuel trims/etc that the ECU can't directly display? Well honestly, those are for tuning and the BSLCDBC can't log the values, so what the hell do you need to see them for? All this should be well-within safety margins and stable before you're DD the car. Is it handy to be able to see the values: of course. Is it necessary: certainly not. If you're rolling around displaying these values on the 3 displays the BSLCDBC has available, you're squandering its usefulness. Until the BSLCDBC can datalog, seeing these values is pretty much pointless unless you're running your car on the ragged edge of what your injectors can handle (IDC), and you should have spent the money on bigger injectors/fuel pump instead if that's the case!

    Finally, what the OP talked about was centered around a nice system that could cleanly and clearly display gauges from the ECU, similar to a car pc using Evoscan to display the data, which by the way freaking rocks. I often use my laptop to display gauges via Evoscan when I get the urge to pretend to be Paul Walker. (still haven't figured out how to make it flash "danger to manifold" on knock count though...) This is great because the gauges are large, analog, datalogged, can be as many as you want, and are very easy to read; which just so happens to be the opposite of the BSLCDBC imho. Also, I never said the carpc was extremely difficult, more-so it's just a hassle. You have to build/buy one, get everything wired in, configure the software, etc. It's a lot of work imo just to see some extra gauges display data that I don't really need to see. I'd much rather spend the money on usable performance upgrades. On the subject of carpc's, I don't know who was talking about carpc's costs, but seriously 2k!? You playing Crysis on that thing or what? You can pick up a decent used complete system from mp3car for around $500 last I checked. Evoscan doesn't require too much power to run, so the pc doesn't have to be extravagant. The skill to actually install one though, that's where I bet most people would fall through.

    Condensed version: Traditional gauges are cheaper, at least equivalent in convenience, and easier to read. The flash ECU can display what's important in one form or another. What can't be seen by either traditional gauges or the flash ECU is only really relevant when you're tuning, and you should have your laptop with you at that point anyway for datalogging. The BSLCDBC imho doesn't truly fit for what the OP is looking for, but it's as good as he's going to get short of a carpc.

    With all that said, I still think the BSLCDBC is a great tool; it's very convenient, well-made, useful, and will only get better as BlackStealth continues to improve it. Is it something I want for my Stealth: yes. Is it high on my priority list: no. There are far more things that I would like to get first, and since I'll be using the flash ECU for boost control, the BSLCDBC serves little purpose. It's only ability at that point is CEL checking and data display, which while those are very handy, I feel the flash ECU and traditional gauges are a cheaper and sufficient alternative. Especially when I can always get my laptop whenever I really want to delve into the data.

    It does go back to personal opinion what you prefer. Until you've tuned and ran a high hp car you may not care too much about knock count. For me running stock internals at a power level few have been able to accomplish without blowing things up you realize how important some parameters are to the safety of the tune. You may not want to know your knock count. A flashing CEL with the flashed ecu is great and all but I prefer to know just how many counts of knock it is. Did I see 5 or 25 counts? There's a huge difference. Depending on what rpm and load it's at sometimes you can't exactly limp the car home to take care of it so in those instances it is nice to know how severe the problem is. Given the fact that my motor survived I can count on more than two hands instances where having the knock sum feature saved my motor whereas a flashed ecu without a laptop datalogging through evoscan would have been necessary. I have a flashed ecu so I'll find out how well it works so I can't comment on if I'll be in a situation where I will need to reflash my map in order to make changes to get safely home, but I think the stock ecu will probably do a good enough job to deal with some inconsistencies related to air and fuel caused by leaks or hardware failure.

    The LCD BC can log all of those values. I have done it plenty of times even if I had OBDII interference from the cable. The newer LCD BCs have a serial expansion card for datalogging purposes. Things happen when you're really pushing a car/turbos. It doesn't stay set it and forget it all the time. Our cars are old and unless you replace every part with a new one there will be adjustments to be fixed or made here and there. I prefer reading my AFR off my AEM wideband and also my oil pressure on a 52mm gauge. There are some things I wouldn't want a small screen all in one type gauge. At the same time there is some beneficial information to display on a heavily modded car that you won't have at your disposal if you're not carrying around a laptop all the time which is what most people will be doing. If $300 is too much to spend on little functionality wait until you get to a big build because you'll be crying at everything. It's not for everyone and if you have a flashed ecu it's not necessary but sometimes pushing the envelope means you're in control and know how things are functioning all the time. It's not a digg on anyone but there should be some clarification on features/uses from someone that has used one extensively enough. Antero made quite a few improvements and added functionality through firmware updates.

    Just the fact that it can pull boost on knock alone makes it a very useful tool for me. Will the flashed ecu be able to accomplish this? Maybe, but not yet.

    After the flashed ecu became available I thought about selling mine, and using the ecu to control boost. At the time ecu boost control was still up in the air as well. I am still unsure if a proper/optimum bleed valve has been figured out for the flashed. After contemplating selling it I decided that the knock count, pulling boost accordingly, and the ability to monitor events around where knock is encountered is worth keeping it.

    You are correct that the flashed ecu handles most of the things that the lcdbc does, and some of the readings are just bonus, and not very easily read, but as of today there is not an all in one option that both give you.

    Help them, for they know not that which they do not know!

    And the other piece of the puzzle? Is there a bleeder valve solution yet? Is this info in the Chrome manual? I do not recall reading about it. Then again I have been reading a lot about a lot lately.

    Now this makes things rough, because I agree with you and disagree with you at the same time. Seeing your knock count is indeed very handy and reassuring, but it lulls you into a false sense of security. It can certainly give you a better idea of how severe the problem is, but it doesn't solve it. I mean when you're rolling hard and your piston shoots through your hood, are you going to look at the knock gauge and say, "well looks like I had 25 counts..." I think not. Likewise, if you're trying to come home after a long day and you see it flash 3 counts, are you just going to rod the piss out of it anyway because it's not that bad? Also, at what load/rpm are you unable to limp the car home without knock? Are you completely unable to stay out of boost, or are you knocking at idle?

    My problem with what you're saying is that you're making it sound like the knock count number is what saved your car, as though a distinct warning that there was knock at all would not have been enough (i.e. the flash ECU flashing the CEL; this is an inherent feature, no laptop connection required). Knock happens and builds so quickly when you have your car pushed to the edge, that seeing the number is far less important than getting off the throttle. I mean, I know you're a smart guy, and even if you didn't have a specific number in front of you, you would have babied the car home to see why your tune drifted. That's exactly why you're making such great power on stock internals after all. I'm not denying that having the number is convenient, but knowing the amount alone doesn't save your baby.

    I also want to point out that you are, at least in terms of the general 3/S population, a rarity. More than 80% of VR4&R/T-TT will likely never go past BPU, let alone be pushing the stock motor to its limits (probably more like 90% honestly). That in and of itself makes your point, while valid, rather short-reaching. Most people run their 3/S as a DD or summer car, and don't want to push it to the limit. I have tuned on the Evo ECU, and the DSM flashable ECUs, so I'm far from oblivious. My DSM ECU had the ability to show knock count via the boost gauge, my buddies Evo did not (well it did have two stage knock count CEL; I don't know if that's possible on the 3/S ECU but it's nice). I found it to be a cool feature, but regardless of knowing the exact knock count I still jumped off the gas like my motor depended on it (because it did, lol).

    Also, unlike the 3/S and Evo ECU that lets you run boost via load, my DSM never got this functionality, and since I tuned by psi, my tune drifting was not uncommon. When I tune I try to go for a knock-free tune (which as I'm sure you're aware is not always possible), and when that CEL flashed I was much less concerned about looking at the gauge to see how much there was, and far more concerned with getting the car home safely so I could get it straightened out. The 3/S ECU is quite similar to these ECUs, and I applaud Greg for pushing it further and further with every update.

    I appreciate your clarification as a product user! First hand information is by far a great advantage; I had read that the newer models were moving to an SD slot in the future, but I didn't know that you could log currently. That makes things far more handy, since you can log and apply that knock count to load/rpm and sort it out. The DSM ECU does not allow for dataloging without a laptop (though Ceddy experimented with it on the Openport 2 cable as it has a mini-SD slot built in and it was promising; I hope Greg looks into this as well, I'd love a constant data feed) and I always thought it'd be a great feature, because as you stated, shit happens right now, you don't always have a chance to grab your laptop and check it out. However, I will say that as a tuner, my dedicated tuning laptop and power invertor are in my car at all times (they fit very nicely under the passenger seat) and as such my laptop is always available. I also have two-way security so you creepers don't get any ideas...

    I also understand that a car is not a Ronco Showtime Rotisserie; you can't just "set it and forget it." My drifting tune in the Talon was a good reminder of that partially because it's old, and partially because the temps in MI would jump from 10* to 60* day to day in the winter. However, the flash ECU with load based tuning/boost control has a much better ability to handle and adjust for that as you stated. I'd say that it really depends how hard you're pushing a car to determine what you need; a person running a stock VR4 doesn't need a wideband even though it's handy, ya know?

    That stated, I liked that you implied exactly what I said above; you're a "heavily modded car," which puts you on a different platform than the typical user. I mean, you're preaching to the choir about the BSLCDBC; I think it's a great product and intend to get one down the line. As for me, I've put over 2k into my motor alone simply to make sure my future goals aren't pushing its stock limits, so I'm not wining about the price. I certainly could have just bought some DR650s and let my old tired motor take it until she puked, but that's not my style. However, much like yourself I am not the norm. The OP asked about it's usefulness and why people would get rid of it after getting the flash ECU, and since his vehicle profile was empty, I went with a stock/typical user analysis. I hate to say it, but these cars are getting cheap and many owners want to spend what they have on what gets the most gains. At this point, his needs and your needs are likely far from the same.

    I appreciate you taking the time to post up; your first-hand experience is very valuable, and the more we lay the information out, the better choice others can make about it for themselves. We may have different opinions, but I know we have the same overall goals: a safe, reliable, fun 3/S, that we built ourselves. I hope your build continues to go well, keep on rocking man.

    Coop, I think you make one of the best points in this thread; the flash ECU can't do everything, yet. Everyone should support Greg and Antero as much as possible for what they give this platform! I'm hoping that unlike the DSM platform the flash ECU on the 3/S platform can be an all-in-one solution. The flash ECU is a robust and well-built tuning solution specifically tailored to our cars needs, what could be better? I want a BSLCDBC in my Talon exactly for the reasons above; if Greg didn't have boost control built into the flash ECU already it'd be going into the Stealth too.

    As Greg noted though the features you describe above are already integrated into Chrome, specifically waste-gate duty cycle reduction on knock. Actually iirc it's in the stock code tied to octane value right along with fuel enrichment, timing retard, and low fuel/timing map interpolation. As for the best bleed valve; afaik Greg has been testing and pushing for the stock 3-port FPR for boost control. MrFred's independent testing showed the GM 3-port BCS to be the best all around (it also can be had for under $50 online), closely followed by the Grimmspeed. He also tested the MAC Valve Antero uses in the BSLCDBC iirc. The GM requires resistors to be wired in-line to be at the proper ECU ratings (many Evo owners run no resistors, but their newer ECUs can probably handle it better than ours); nothing too crazy complicated. I'd have to see the resistance specs on the Grimmspeed, but I'd be willing to bet the Evos are very close to ours, making it splice and play.

    The stock FPR will likely be what we roll with here since on average we run much less boost, and it's plug and play. That said, the GM is bigger and more responsive, allowing for higher levels of boost control, which will likely make it the go-to option for those with big power goals. Greg will have to shed some light on what hes come up with so far. Honestly, there's a lot of information from testers floating around the forums, from BCS info to how far you can push dwell times. Finding it all is half that battle, and when it's all well-tested and confirmed I have no doubt Greg will be the first to let us all know about it.

    PS: Hate to double-post but that darn text character limit is killing me. Maybe I should have been a writer?

    If you have upgraded waste gates, the stock BCS works fine. It's the 80% of the guys who stick with stock waste gates and upgraded turbos that need to upgrade.

    There are lots of options for this. Just not a lot that has been tested.

    Thanks for the info, I will look at this further and decide which way to go. Did not mean to derail this as I have. Like I said, I am stuffing my head with so much that I have to sort things as they come, which sometimes I lose bits.

Seeing your knock count is indeed very handy and reassuring, but it lulls you into a false sense of security. It can certainly give you a better idea of how severe the problem is, but it doesn't solve it. I mean when you're rolling hard and your piston shoots through your hood, are you going to look at the knock gauge and say, "well looks like I had 25 counts..." I think not. Likewise, if you're trying to come home after a long day and you see it flash 3 counts, are you just going to rod the piss out of it anyway because it's not that bad? Also, at what load/rpm are you unable to limp the car home without knock? Are you completely unable to stay out of boost, or are you knocking at idle?

    My problem with what you're saying is that you're making it sound like the knock count number is what saved your car, as though a distinct warning that there was knock at all would not have been enough (i.e. the flash ECU flashing the CEL; this is an inherent feature, no laptop connection required). Knock happens and builds so quickly when you have your car pushed to the edge, that seeing the number is far less important than getting off the throttle. I mean, I know you're a smart guy, and even if you didn't have a specific number in front of you, you would have babied the car home to see why your tune drifted. That's exactly why you're making such great power on stock internals after all. I'm not denying that having the number is convenient, but knowing the amount alone doesn't save your baby.

    I also want to point out that you are, at least in terms of the general 3/S population, a rarity. More than 80% of VR4&R/T-TT will likely never go past BPU, let alone be pushing the stock motor to its limits (probably more like 90% honestly). That in and of itself makes your point, while valid, rather short-reaching. Most people run their 3/S as a DD or summer car, and don't want to push it to the limit. I have tuned on the Evo ECU, and the DSM flashable ECUs, so I'm far from oblivious. My DSM ECU had the ability to show knock count via the boost gauge, my buddies Evo did not (well it did have two stage knock count CEL; I don't know if that's possible on the 3/S ECU but it's nice). I found it to be a cool feature, but regardless of knowing the exact knock count I still jumped off the gas like my motor depended on it (because it did, lol).
    It comes down to my personal preference again but there's one thing I have and will keep the flashed ecu doesn't have and that's "real-time tuning." None of this shut the car off to flash a change to my map. I will of course do that when I run the flashed ecu but I will make sure to keep a piggyback for real-time tuning even if the sole purpose of it is just for an upgraded 600+AWHP supported MAF and nothing else. That is probably the number one reason why I prefer to know the number of counts of knock I'm seeing in real-time instead of a CEL flash. Knowing the number of counts of knock, my rpm, AFR, etc I can determine from the conditions which way lean or rich I'm running from my target AFR caused by vacuum or boost leaks I will encounter occasionally causing some part-throttle induced knock. Given I can tune it real-time and see how bad my knock is it gives me an idea how much to change my fuel since I'm not messing with timing. So I end up literally fixing my knock issues in a matter of seconds instead of much longer using other methods. If I could tune in real-time with the flashed ecu and still went off the CEL flash on knock but did not have Evoscan logging or a laptop it would be either a guess and check type deal to see if it was gone or in the case of no laptop no fix until I got home. For me I prefer to fix the issue immediately as best as I can to get me home so I can go back and have the root cause of it all fixed when I have all the tools available. At least in my case I have found real-time tuning to be an invaluable tool which is one downfall of the flashed ecu but for my limited purposes of use I can work around it to get by.

    The only gripe I had about the LCD BC was the fact that with the MAC/AEM boost solenoid I could not get the valve to react fast enough to the fast building boost of a small TD04 billet turbo. I changed the settings quite a bit and could not get rid of the boost spiking and general poor ramping/spooling issues while using it. I'm sure it was due to user error and my lack of OBDII datalogging cooperation that kept me from getting it to really work so I swapped back to a MBC which no doubt in my mind helped me pick up 50-100AWHP. It was nearly a night and day difference in boost stability. I felt like I increased the boost 8-10 psi because it kicked that much harder. I still attribute it to incompetence using the MAC solenoid so I will revisit it again since it still sits in my engine bay at a vacuum hose swap away, but nevertheless was a frustrating 4-6 month ordeal not having it work right. I'm anxious to see a good boost solenoid for the flashed ecu that will handle higher pressures because ecu controlled boost is the way to go imo.
