My ignition timing is all over the place in 1st gear and 2nd gear. It goes normal in 3rd.
Cant figure out why.
the 2 deg low in 3rd gear is due to coolant temp high.
The tune is the one i pulled at the track
The Log file is a 14.02 sec at 98mph. Think there is a lot left in this truck if i could get my timing under control.
I tried pulling the abs fuses to elimnate a traction control input problem. did the same thing with fuses in and out.
