Im not an expert on this but what I have read, the emanage sits between say stock ecu and say injectors. When stock ecu picks up data sent from the sensors, and resending data to injectors, emanage is adjusting this data and send it to injectors. So the stock ecu doesnt know there is any difference..correct me if im wrong anyone...LOL..
plus,,if anyone knows anywhere cheap to get my car dynoed...pls let me know..I cant wait to see what number my car is pulling with these heavy 12kg 19" rims lol.
