Knock advance retard probleme.

[Rotxam]

Hello,

I have internal knock module on MS3, i test advance retarding.

I test with 36-1 wheel on my press dril in toothed wheel mode.

I test EDIS and Basic trigger mode with Megastim, and i never see advance retard.

I can see variation for the knock input in TS gauge but no Knock Retard, always 0.0 deg in the gauge.

I am several hours of reading and research to find a solution, but for the moment its does not work.

Can you help me?

Thanks

Is that possible to test a knock sensor retard advance signal with a bench tests ?

Yes or no?

Thanks

It's going to be tough - you have to spoof the right frequency at the right crank timing.
