Hesitation in part throttle acceleration, WOT is ok

[unicoder]

KA-T.

My KA-T has been a lot of fun putting together, and even more fun driving. Had a couple issues to sort out, but now I can't put my finger on this one!

When I search bogging/hesitation threads, none seem to go over intermittent issues like mine. Seems some days it will pull at part throttle/wot fine, while other times, it hesitates at part throttle boost, and seems to pull ok in WOT

Pump is a new ISR 255lph, with a new Z32 Fuel Filter, and brand new reman 370cc injectors. MAF is new reman z32 maf


Could this be fuel starvation? Car idles, cruises and even pulls hard, plugs look good!

Do you have a way to log all your sensor inputs And afr? That's the only way we can help stuff like this.

Check the fuel map

Got no fuel map to check?

Invest in a computer where you can adjust the fuel map
