This is absolutely weird. I've tunemd many cars without problems, but can't get my own crap figured out...
I'm seeing 6:1 AFR during WOT at full boost. No stumbles or backfire, but there is some black smoke on acceleration. Leaning it out induces knock and still won't bring ut my AFR above 7:1. I know I'm running rich, but 6:1 rich?
I'm running GM maf set for 660s and SAFC. No timing control. FPR set at 37psi base. Base timing is 5*. Running 17psi on turbonetics RS65. Car pulls good, but I suspect not as good as it could. Conpression is 155 across.
I'm using INNOVATE wideband unit. I've already repaced WB O2 sensor, thinking that old on got fryed somehow, but still see same numbers. I have checked and re-checked everything. At first, I thought it was high timing, that was responsible for the knock, but after I swapped evo3 16G for RS65, I no longer have timing problems (like 30* at 3400rpm at full boost).
What am I missing?
My wb o2 is tapped into DP on the first bend. Could it be too hot there for it? Operational temp for that sensor is 900F or below, but it has a warning, where if temp is too high, display unit informs you of it. I get no such thing. Can a car even run smooth with 6:1 AFR at WOT? During cruising, my AFR is ~13:1...
