Bit of background... Car '89 325is, stock motor.
MS2 kit from Dederic Motorsport installed because the car was cutting out at 5600 rpm previously and I have eventual plans to go to wasted spark and to eventually supercharge.
At this point I'd say I'm still very new to "tuning".
My previous thread on the 5600 rpm cut out is below:
Link to current tune and log (tunerstudio) showing the cutout (car in neutral in driveway):
So after installing the MS2, the car was driving fantastically. But then all of a sudden, the cut at 5600 rpm came back! Cuts out every time at about 5600 rpm.
So, looking at the log it looks to me like the car is losing the crank position sensor because the RPM's are all over the place. But the MAP and AFR's are also all over the place (but maybe due to fuel cut...?) Could I be losing multiple sensors at once?
I've changed the Crank Position Sensor 3 times in a year. I feel like that shouldn't be the issue. Looking for some opinions before changing it again.
