fuel map changing

Postby Kevspec » Wed Jan 08, 2020 7:31 pm

i have since fitted new injectors to my car and used the kinjflow calculator to get correct values but ecu keeps doing weird stuff and making my idle rich and load tables lean. the injector i have fitted will defiantly not max out on this engine combo but in the tables at wot numbers are set very high to run correct

Don't get to caught up on the IAC operating while driving, it's meant to.

Did you change the voltage offset table to suit the injectors what kind did you have and what did you fit
If Its Got Gas Or Ass Count Me In.if it cant be fixed with a hammer you have an electrical problem
