B23ET, 630cc Siemens DEKA
Trigger 36-1 on front pulley
Volvo VR sensor (with small tip)
Problem sometimes around 6000rpm trigger error lost of rpm signal this happens often when the throttle is released between gear changes.
- absolutely certain that VR sensor polarity is good ?
- is the pullup 18k ? (should be if originally ordered with VR input. If ordered with HALL input that has appr 3k pullup and modified to VR at home, than this must be doublechecked)
- measured sensor resistance = ...
- measured DC bias on the VR signal = ... mV. This should be around 5000 * Rsensor / (18000 + Rsensor) milliVolts
- Could it be the bracket for the sensor that flex of vibrations?
- maybe
