Working on a 6.1 L swapped charger R/T with an A580 transmission. Engine tune seems to be okay.
3.91 Gear
29" Tire
Cam
Heads
Intake
Exhaust
3800 Stall
First issue is that under wot acceleration in 1st and (no traction) the rpms overshoot and the transmission goes into limp mode
I have the max RPM in the trans set to 6400rpm and the limp mode trigger 1000rpms above. The engine revlimiter is at 6500 RPM
Secondly, in the Auto-Stick mode the transmission is shifting wayy too early. Like you pre-load second and nail it at 2500 rpm and it shifts at 4k rpm.
Could this be related to the 4200rpm limiter in the engine tune with MDS failed?
Tune is attached, thanks
