When testing on a Stim, do you get an RPM signal in Stim for Wheel mode?

If you are losing RPM, please post a tooth log of the problem. This is a special purpose log for dealing with RPM input problems.

If it seems to drop out with it cold, try adjusting the VR trim pots.

I just replace d24 and still have the same problem. It don't matter if it's cold or hot, if I hit the throttle its gone.

....which you shouldn't be using for the crank sensor.

Adjust the VR trim pots.
