1600 RPM fuel cut?
Posted: Sat Aug 28, 2010 5:42 am
Hello
I have an R33 with rb20ECU, I manage to get the 14.7 range AFR but if i accelerate slowly between 1600 RPM and 2000 RPM I think the fuel is cutting off and the throttle will not respond.
Even if I make the AFR richer, when it reach the 1600 to 2000 RPM the throttle will not work, but just only if I do it slowly if I press the accelerator hard it will rev normal.
I attached the map that I'm using and a log at idle.
Than you
