DP ECU vs PCIII etc
I'm currently running the S2R with a decat, end cans without baffles and standard airbox/filter. I will probably go with a K&N filter but have yet to decide on if I want the open airbox or not.
My question is I already have a DP ECU fitted, is there a need to have a PCIII or similar engine mapping thing or will the DP ECU be sufficient?
