Default Light cruise A/F
You guys running MAF's and dedicated Wide Bands what A/F does the ECM keep you at while in light cruise and idle?

Should be in closed loop with the PCM targeting 14.7.

I run mine 15.5 it's sometimes 15.2-15.7 but most of the time it's spot on. No SD should command 14.7 or 14.8 as mentioned.


COS3 SD FTW
