Nistune Forums

My Wideband is on the fritz so I can't try this out until I get another O2 sensor but..... could we crank up the values in the areas affected by the throttle? That way, when you let off the throttle on a hard run, the shutting of the throttle would help bring down the excess fuel on decel.

Here is the setup: R32 GT-R, T72 turbo, 1000cc injectors, high lift 264/272 cams, 100mm throttle, 4" IC piping, big FMIC, Ford MAF... Okay so I got sick of the HKS VPC + GCC and installed the Ford Lightning MAF sensor into a 4" pipe before the turbo (T72). Getting a starting K value to wor...

Cut to the chase, my biggest problem right now is the throttle tip in, on a slight push sends the AFR super lean and makes the car bog. What do you suggest adjusting to smooth this out? The throttle is 90mm. Here are the details of what I am running: BNR32, N1 engine, stock 2.6L bore, stock compress...
