I don't understand that problem is the first time that happen...i swap a b16 gen 2 with a stock p30 ecu in my 92-95 coupe...the two first week my vtec was at 5800 and end at 8500...and now its start at 6400 and cut at 8200. The only thing i think it is, its my oil pressure its not perfect...but on my gauge all is ok.


i swap a lot of dohc vtec but its the first time i run a bone stock motor in one of my car, i dont care very much because its my winter beater but im just curious about to solve that problem.

thanks for the help guys

 

anyone can help me in this one?
