I got slope breakpoint and offset for my injectors now. it idles very well but when I go wot I get 1.2 to 1.3 fuel error % and I get a wideband reading on tuner pro of 7.80-8.20 actually gauges shoes 10:1 then it pegged rich. I'm not sure what I need to adjust maybe something like WOT VS RPM would help I'm still learning and I adjusted my maf at idle to get the right fuel error of 1.00 at idle and around 2000 rpms I try to get it to match 1.00. my adjusting the maf transfer at that mafv voltage then I multiply wherever the fuel error is for that voltage and change it to a new value for each voltage I could get a reading from idling in my garage up to 2000rpm. I'm not sure if that's the correct way to do it as I used 98 explorer bin injector info someone posted in the forum that I asked for there the F6VE-A5A 0280 155 710 19lb injectors. but then again I am running more fuel pressure than stock so not sure everything is set right for 55psi.

you have the wrong adx file for tunerpro

the wot lambse multiplier cannot dial in fuel, you need to dial in the maf
