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
1600 RPM fuel cut?

Re: 1600 RPM fuel cut?
noticed you have no TPS idle light going on at all
If its an R32 ECU then you need the custom firmware to read the TPS voltage input and simulate the TPS idle switch
May have to reprogram your board
