What did you do today to your 3/S?

[Sin'sVr4]

Ok, first off, the I drove over 100 miles to JFAST and the car ran perfect! I was taking it up to him to go thru the car and check the tune. Seriously, the car didnt have a hiccup at all. He looked at the fuel and ignition maps and started adjusting the cells and then the car ran like absolute shit. So, we pulled over and reloaded the original cal config and the car still ran horrible. Dont know wtf happened. I know my car never skipped timing ever. EVER. I dont know wtf Jer is talking about, but the car ran like a champ on the way up there. Thats why I PAID JFAST to go thru my car.

I didnt RACE my car with the issues like this. Im not fukin stupid. The AFR was all over the place and THATS an issue I wanted to have looked at. But, i was taking your guys advice to have someone look at my car. Even my wife said wtf? She said it ran perfect on the way up and now it wont even move. I know the difference from a healthy car and a non healthy car. I only needed to find out why my car had no SERIOUS power in 3rd gear. My 1st and 2nd gear was amazing and 3rd would pull but took awhile to get there. Plus my speedometer I found out is off 5 MPH (too fast)

I just know that when my car at the track runs great in 1st and 2nd then boggs in third, its not getting enough fuel. JFAST looked at maps and said I had no fuel or timing setup correctly in that range. Thats what he is doing. How the fuck did my car jump timing? Never in my life have I jumped timing and never have I ever heard my valves slapping. wierd that you say that Jer. Hope you find wtf happend.

That's a heck of a rant and incredibly insulting to the guy that's going to be working on your car. Good luck with that...

[Sin'sVr4]

How was I insulting him? Why would I insult Jeremy? I am pissed because he said it jumped timing. I know how my car ran on the way up there and then it ran like shit with him there. I didnt want him to think I drove it up there the way it was driving when we were together. Like I said, im not stupid. If you took as an insult towards him then thats your POV. If anyone else did then Im sorry, that wasnt my intent. When my car was riding perfect, then acted like a different car, just cracks me. I know jeremy will figure it out.Thats why I wanted him to do it because he is the one I know and trust. My laptop started to completely implode the cal he was working on. Literally started to just delete cells. We were like wtf is going on? never seen that and logged into my laptop tons of times.

Again, the car acted like there was no fuel for some reason. I suggested maybe the hose for the fuel pumps could have came off. I am betting money thats what happened as i reinstalled my 400 and 255 wallys before I left and the fuel gauge float was pinched and it wouldnt read the guage and i just filled it up. Anyways, it was a rant becasue i dont know wtf happened. I didnt blame J at all. He knows wtf he's doing. If i didnt have confidence in him, why would I take it to him? he's doing me a favor. Thx for letting me vent Adam. I just dont want people to think I drive my car not healthy. Everytime I took it to the track, it ran great, just want the tune looked over and another set of eyes to see something I dont in the engie bay

Ah. The rant I quoted really sounded like you were blaming J for everything wrong other than your car being slightly down on power. As for the timing thing, it's really easy to jump timing in these and if valves don't bend, people often don't notice.

Seriously, I'm not going to call you an idiot but it really shouldn't be that hard to take off the timing belt covers, physically see the timing off, or watch the wideband seeing it rich at idle plus full lean at partial throttle. Leave it to the experts from now on because it probably isn't a good idea to do much else than change oil and spark plugs until you understand a little better how these cars work. I'm glad Jeremy is getting it straightened out again. You should be in the 10s in no time Sin.

man, internet warriors.

J will have your shit up and tip top in no time. Hang in there.

wow. lol'd at this. Even tho ive done everything on my car except tune the car. This includes tranny swap and build, all turbos and top end. Just dodnt press the pistons in and crank.

My wideband has always been wacky since the day it rolled off the dyno. IDK, but that is why Jer has my car. He's the expert, not me. Wow, funny how you have no idea who i am and what I am capable of and balls that people have staring at a PC.

He already said my PTU went bad, and timing. Said the car is runnning great but seems to be running out of fuel. I just put in the wally 400lph E85 pump which On Chris hills site says not to use unless u have 500+ hp. So, if I dont have enough pump why would that be stated on the description? I am just frustrated because I went with that pump for a reason. Either way, I have my guru working on it. We will see what is going on. Gonna pressure test and check my boost controller. wont go past 20 psi and falls off hard

[J. Fast]

Tune on the car was not okay Mike. The cal you dropped it off with is a pump-gas calibration. When we test drove it the engine was falling on it's ass because it didn't even have enough fuel to run. However, if you recall your AEM widband was pegged at 10.5 / 11 afr's. I stuffed my Zeitronix WB in the tailpipe it was reading 17afr at idle. The wideband on the car appears to be ground looped and is not reading correctly. It stays pegged at 10 and meanders all over the place, zero's out, resets, and etc. So there's one issue that will need to be addressed.

Timing was no big deal, took a couple of hours to dig in there but it's good to go now. Reset base timing and re-syc's timing with EMS, all is good. When I finished up I checked compression and camera'd the cyliders with my snake cam. No signs of kissing and the compression numbers were 125,123,122,125,126,124. Engine is healthy, nice to clear that hurdle.

Got into tuning for about 3 hrs or so. All the bugs appear to be sorted in all ranges up to 18psi. Engine runs impressive everywhere but won't boost over 19psi. There appears to be a 19+psi intermittent boost leak and a fuel pump or injector max flow issue. I hit the ceiling on the base fuel map and need more fuel. Doesn't look like the EMS will give me anymore IPW with the current style of injector/batt offset. Will be digging into the fuel side tomorrow.

Let's see, what else... The good, the brakes work great, no leaks, no ignition issues after replacing the PTU.

On my list of things to keep an eye on.

Oil pressure gauge is intermittent. A few times I looked down at it was pinned at 80psi at idle and then worked it's way back down to about 20psi.

The cab wreaks like fuel. There's no gasket at the fuel bulkhead fitting. The tank appears to be venting off some fumes into the cab. Makes you stomach sour after awhile.

AFR dropping at high boost range, gotta look into possible fuel delivery issues tomorrow.

Manual boost controller does not appear to work. I set the wasegates to 18psi and that's the max boost I can currently make. No matter which way I turn the knob on the Hallman gives no more or less than 18psi.

Everything else is all good.

Here's the cal you had loaded on the EMS that I drove to my shop from themall with bro...

Previos Timing Map:



Previous Fuel Map:



Here's the current tune...

Current Timing Map:



Current Fuel Map:



Pick a fuel cell and look at the fuel demand increase... from what you came with vs what you have now +25% or so. Car runs nice

Notice the top of my fuel curve is flat because I can't hit those cells because a boost or fuel issue needs to be resolved and I havent hit those cells.

How far you want me to take this tune Mike? You want me to fix the issues so I can crank it up or leave it and go with what I've handled so far?

[Sin'sVr4]

well, thats up to you bro. i want it to be safe, but i want that power too. I text you earlier, lol that is all I can do. Melissa is about to fukin leave becasue of this. Big thing is why is there no fule and wtf is up with my boost controller? well, if u do a boost leak test hopefully you can hear something i didnt. I know my coupler on the front IC pipe off the front turbos has a tear somewhere. i need to buy all new ones. just not sure what the sizes are. ugh...

awesome job jer btw. You the man bro
