hi everyone
i have a r33 wth a rb25-30.
i have a rb20ecu with a nis tune chip. has anyone got there rb25-30 running with a rb20 ecu?
i have upgraded turbo, pistons, injectors, fuel pump, q45 afm, front mount intercooler and full turbo back exhaust.
my mechaic has told me this ecu cant be tuned so we are trying the standard computer next. he has told me to get a apexi power fc if he cant get it to run. because its running too rich.
i have contacted toshi off the forums and he said he can tune the rb20 computer to suit the engine.
has any one had this experiance before??
any help will be much apreciated
thanks
