Do i need re-scale my MAF？
Sorry for my poor english.hope i can make my clear.
I got a MY17 brz（cal id:ZA1JK00N）. Nameless UEL header(similar like tomei)，stock overpipe，highflow cat frontpipe whit 2 resonators，handmade downpipe with resonator（yes，3 resonators in all cuz i hate drone） and muffler。OFT OTS V4.03 STAGE 2+ GAS。 I found my LTFT is -4.69%~-10% last night and is summer outside 40C+。 do i need re-scale my MAF？ I compare OFT OTS with stock，the MAF scale is higher 5~10% than STOCK ，but i just use stockintake。is that OK and why the OTS tunes like that？ BTW：it seems i can`t find proper RR-LOG-DEF（now is 370）for my ecu，and when logging with RR，I just can get data of standard OBDII protocol PID。is there sth wrong？ appreciate guys！ |
