My questions is whats the difference between a b16 ecu and a b18c1 ecu as far as timing and fuel. The reason I ask this is because I just finished putting together my sleeved block and i am now in the process of breaking it in with my turbo kit on. My car is a 00 civic with a obd2b b18c1 engine but the ecu in my car is from a 00 si. I am concerned that the timing is far more advanced compared to a b18c1 especially for boost. thanks in advance.
