for you true tuners out there

i planing a trip back to the dyno (although if tpr releases any of there products in the near future, i might delay my trip)
and i was wondering what a good a/f ratio would be runing on 93 octane with i/e and of course pfc.

as a general rule of thumb, 13.0 to 1 is the ideal mixture for power, but i dont know for sure as far as the celica goes, whether someone has dynod with different mixtures.

Pray to GOD that your tuner knows the answer to this question.

for max power you can go as high as 14.0 (highly not reccomended)


for daily driving 13.0-13.5 is acceptable, depending on how precice your tuner is if he can flat line 13.5 and not 13.6's you should be just fine for daily drivability.


your knock you need to watch and keep it under 30. do a few pulls in 4th and 5th gear that seems to bring out the worst in knock between 4500-5500rpms.

also let your tuner know the pfc uses a bit of "dumb tuner" hysterisis.

so when hes tuning let him know the pfc pulls values in a cube around the affected cell and averages them out.
