I will upload an updated version this afternoon. i have found an accurate torque curve and have updated that. I have also managed to make the engine flat-shift like a DD2(no lifting when shift gears). I am now trying to find a way to disable the hand clutch.

If you set the gear ratios like that, the top speed is 32km/h
because you forgot DD2 engine internal ratio is 1.
try this, i changed also engine weigth, rpm limiter, breake engine rpm, rpm engage clutch, opt engine temp, low and higt engine temp (change these values also in others files otherwise alert lights will not work properly)
