Some background first as I'm new here (registered last year when I purchased the car) and new to DSMs: I bought a 93 Talon November of last year that was wrecked. Owner lost control on ice and hit a curb and damaged the rear subframe. The owner hadn't owned it very long when he wrecked it, then he let it sit about a year before selling it. It was obvious he didn't know very much about it since I asked if there was anything done to it and he said it seemed to be stock. What I discovered after purchasing the car was a full 3" exhaust - downpipe, no cat, magnaflow muffler. Somehow noticed the stock boost gauge moved when the key was on so removed the ECU to find it had a chip installed. Just has a sticker on the chip that says "Stage III". Found the old style Apexi SAFC with the adjustable knobs installed in the glove box and it works. Also has a manual boost controller and a rewired fuel pump. Not sure on the pump but assuming stock as there is no AFPR.
Anyways, I've since fixed the car along with several other things that needed fixed or replaced. Also found out it has a 6 bolt swap and no balance shafts when I did the timing belt.
I could go on but my main point for this thread is to find out more about this chip. The car has a problem with boost creep I'm sure from the exhaust on it. I swapped to an AEM boost gauge fairly early on after getting the car drivable as the mechanical one that was installed was junky. The new gauge showed 10 psi then it would start creeping around 4500-5000 rpm up to 20 psi, sometimes as much as 22. I never did hold the car WOT in higher gears before this and after seeing this I made sure not to. A couple months ago I installed an AEM wideband and to my surprise it's not lean at all.
The car has stock blue top 450cc injectors and the SAFC is all zeroed out yet at WOT the AFR is 11.1-11.2 and when it starts creeping, the AFR actually richens to upper 10's all the way to 20 psi. I'm confused as to how the injectors can keep up with this? I also know nothing about the chip at all and any info would be awesome. How does it work for tuning? Does it just target an AFR? I've learned it has NLTS and launch control and have since moved the clutch wire to the top of the pedal travel instead of the bottom when I had to weld the assembly. Which reminds me, really stiff clutch pedal and I can see a yellow pressure plate in the window there the clutch fork is so I'm guessing ACT of some sort? Also I'm still careful with the car since I have no way of seeing knock. I just placed an order for ECMLink so I will have it soon. Is there a way to log with Link without installing the chip? Like, can I log with my current chip? I'm sure I'm forgetting stuff but I've been learning as much as I can.
