Ok had some starting issues,got those resolved no problem.I have a bad stumble if i stab it under about 1600 or so,it has a 256 at 50 cam 630 lift range,long tubes ported t body.

My fuel trims are within 1 to 2 percent to the rich side everywhere and wot is 12.8 20 degrees timing with no knock,but when you stab the throttle at low rpm it almost soounds like a lean pop threw the intake,but trims stay good along with a/f...Please help thanks.

And yes this is my first time with this ecu e38 thing.So far not a fan.This is my last issue with it as i will be turning it loose once i get this last little problem fixed.Thanks

aLSO Ive tried turning spark smoothing on and off,along with disabling trac control and tq control,with now help.

Ive also tried adjusting where the pe comes in at vs tp and rpm with no help,seems as if everything i try has no effect.2000 and up its good,just anything under that and i have the stumble/what feels like a lean pop.
