I've been having an issue with my car running like a piece of shit. My fuel setup is:
Hotwired Walbro
Denso 720cc
AEM FPR
ARC2 w/ 87mm MAS
Low -5
Mid -7
High -6
Accel +3
(this setup was posted by Hellbringer on 3si, who had roughly the same mods)
The first problem I'm having is that my ARM1 ALWAYS reads the second to last lean light. I've already tried adjusting the low knob everywhere from -5 to +5/6 and the ARM1 refuses to dither. My o2 voltages change for a minute or so on my logger and then go back to sticking at certain numbers, after the car warmed up this most recent time I started it, it was:
Rear o2: .80-.95
Front o2: stuck at .99
ARM1 reading lean as always and idle at ~800. Which is odd because those o2 voltages are rich as hell, right? It shouldn't even be running if it's reading constantly that rich. The weird part is that this area of the log is where the car runs best.
When I first started the car it was:
rear o2: .03-.06
front o2: .11-.15
ARM1 reading lean. Idle ~1000.
Eventually after it warms up the idle smooths out for a bit and then it slowly dies. Vacuum is reading -50~ hkpa at idle.
