From a dead stop @ idle (in or out of gear) and you hit WOT - I get a bog/hesitation and then it clears up over 2600 rpm or so. I am commanding 1.00eq throughout the entire table (for VE tuning). VE table is happy, car runs excellent at all other RPM ranges - except off idle WOT.
When I hit WOT - it stumbles and the wbo2 maxes out at 20afr (lean spike.. right?) After hitting at least 20 or so counts on the AUTOVE. The 95-105MAP @ 1200-2400 RPM say I need to add 20% to the VE on those cells.
I've added over 40% and nothing seems to change.
A little about the car:
'98 Z27 A4 3600VIG 3.73s
Cam only LS2 240/244 .598 .610
Fast 90/NW 90
SVO 42s
Racetronix fuel system
...and all of the other usual boltons
It seems pretty obvious this lean spike is causing my bog. I am not getting any KR but my timing appears to be dropping down to single digits and I cannot figure out why.
Would someone mind looking at my logs and tune? (please ignore the skewed VE table)
Thanks,
David
