Trans is a liberty 4 speed, 2.19 first gear and a 7300 stall converter.
I m way to lazy to use a clutch

I have tried to eliminate the wheel spin by lowering start rpm but I still end up with that same 1.29 -1-31 60 ft

If you look at the engine rpm at 1 sec, do anyone see anything weird?
since my laptop died I don t have all data here but I remember about the same time the lambda sensors shows a rich condition one one side only
( da vinci dominators on CFE sheet metal tunnelram)


the small peak just before 4th is a bump in the track, shocks may very well be a little stiff

more info here, converter and first gear changed since
