this is for my S14, i got some 750cc injectors getting ready to strap my gt30 but in the mean time i want to drive the car on the stock snail.
i don't have the commander so my friend is letting me use his for a few hours.. i don't want to be guessing around, is there a setting that will allow me to trim the entire map at ones, i know i could go around and apply a fuel multiplier cell by cell but that will take some time.

 

You can go to the PIM map and do it by boost (PIM V/map sensor voltage) and or RPMs. Otherwise you need a DATALOGIT.

 

damn, i got an lm-1 with the rpm converter so i guess i'll just set that up and go for a street tune...
