im trying to look for the best ecu i can for my h22. i had a " bootleg" version of a chipped p13 and it ran like shit. what about possibly a p72 or a p28?? would i be able to run one of those?? not like i have anything against the p13 but things like not having a knock senosr, and my vss not working will effect performance. what i really wanna do is go 2 a stock p13 and get a VAFC but i dont think you can disable things such as knock sensors and vss's on a VAFC right????
