I just saw this post this morning and since I just installed a MPT tune last Friday and was running errands today, I thought I'd check mine. My numbers are exactly what Artem states here! Being a leftover from carburetor days 11.8 seems kinda lean at WOT, but you can't argue against the results. The tune was 91 Race.Stock Tune:
AFR @ Cruise: 14.0-14.2
Unleashed:
AFR @ Cruise: 14.6-14.7
AFR @ WOT: 12.1
MPT:
AFR @ Cruise: 13.9-14.2
AFR @ WOT: 11.8
Can anyone confirm AFR @ WOT on stock tune?
Actually 11.8 (seen some MPT cars as low as 11.4) is fairly rich at WOT for an natural aspirated vehicle. That is entering FI territory (10.8-low 11's) but not quite. I prefer 12.1 at WOT for n/a applications. Even 12.8-13.2 you're safe (n/a), people don't realize too much fuel can be just as catastrophic and too little. Each to their own though..I just saw this post this morning and since I just installed a MPT tune last Friday and was running errands today, I thought I'd check mine.

I'm running a SCTx4 93 tune and my AFR is 14.0 -14.2 cruise and 12.0 -12.2 wot.I just saw this post this morning and since I just installed a MPT tune last Friday and was running errands today, I thought I'd check mine.
