Tuning returnless fuel pump

Unread postby VJordan » Thu Feb 13, 2020 8:56 pm

How would I go about tuning the fuel pump , I have a hesitation shifting wot the fuel pressure spikes when off the gas then drops and goes lean when back on the gas. I realize that’s gonna happen with returnless because the fuel has nowhere to go and most people solve it with deleting the pprv but I would rather try to tune it out is it possible with the pids?

Also on cvaf1 the adx dashboard fuel pump input voltage doesn’t change so can’t really log it and the o2 sensor voltage doesn’t change either
