fuel map changing

Post by Kevspec »

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
