So who wants their ECU's "Chromed"?

No. The car will run better with both trims enabled like stock.

Periphery 0 disables/enables a bunch of functions. Periphery 2 and 3 control the DTCs (check engine lights). I've found it's best to completely leave periphery 0 alone and only turn off the CELs in periphery 2 you don't want. Of course, in V1 many are wrong... :(

V2 will be 100% accurate though. I've verified each bit in my car.

How many factory forced-induction cars come with a speed density setup?

No it can not solve the issue. Performance wise it's better to have a closed loop BOV.

I'll never understand the need to have a smoking car that "sounds cool" when you shift....

Anyone have any good reads on the basics of tuning?? I want a starting point and an end point. Ive watched the ecuflash tutorials, ive tuned cars via dsmlink on pumpgas and e85, but ive never really read in depth from start to finish about the theory. Links to threads would be good. I was browsing Trevor's old thread on 3si about how its best to get IDC's at 80% when using an afpr to keep the ecu in the optimum timing tables, etc...that stuff is so ancient..:p

So if anyone has anything...please post up.

The 80% IDC is only when using the stock ecu with piggybacks. It's an indicator of where you are on the stock fuel and timing maps based on the factory injector scaling.

With ECUflash you can simply change the injector size so aiming for a target IDC isn't important of course you don't want to exceed a certain IDC. For instance when I had my 680s in I was in the 90's for IDC now with the 1050s I'm in the 50-60s at the same boost right in the nice part of the timing map as It's determined by "load" and RPM and not IDC.

MUT table is the same as this post.

How To: Logging more than 160 Load and 1600HZ with EVOScan - 3000GT/Stealth International Message Center

So yeah in ES 0.3125*x MUT request 00 and 01, 2byte Hz is 04 and 05. Looks like that's where the problem is..

Quick and possibly dumb question..... I need to have Monochrome's xml file on EVOscan v2.6 to properly log my flashable 98 sl ecu?

It looks like he needs to re-host the links :)

I'd really like to get a 13G/DR500 class car on a Dyno to tune.

My ecu is in, along with Bob's dual core. I should have everything back together either this weekend or next, then I will dyno the chromed setup. I'm sure it would be a lot stronger with a tune from you, but I am anxious to see what it does vs the old arc-2 tune (355whp 380 ft/lbs)

With Toni's car there was a little bit of a difference over the MAFT/SAFC combo in terms of peak power. BUT there was a huge difference in midrange! Almost 40hp!

The best guides are on EVOm. There's a thread stickied in the ECUFlash section called "how to tune an EVO". Same exact concepts apply with our cars. In fact, I've found a 16part YouTube video now too.

The "how tos" are out there.

Yeah, I'm aware. Greg I've watched the youtube video series also...
