Basic PCM Tune question
I have an Ed Wright PCM and was wondering if it is typical for tuners like him adjust the air/fuel for steady speed conditions. Of course they lean out the full throttle. Just wondering if that is done everywhere.

Re: Basic PCM Tune question (ericcer)
I've had a peak at a few tuner programs and yes, they tend to play around with the timing and either the MAF Calibration table or the VE tables. This will affect part throttle and steady state cruising.
FWIW, Ed locks his so you can't see what he does. Guess too many people were sharing his tunes via the 'net.
