I'm using a two wire Bosch knock sensor on my engine with 86,5mm bore.
Wiring
....
Testing
- Cling the block with wrench and record with soundcard.
- optional:
- Check FFT for freq.
- Upload the wav.
I setup the knock parameters in Megatune as discribed in MembersPage/PhatBob/UserGuide,
Problem
But my knock diff gauge displays 1000000. What can this be? It stays the same if sensor is connected or disconnected from cable harness.
if you capture mll (in terminalprogram, while on knock page), can you paste more ?
