What is the sensor connected to the VR input? It's the norm now to use the VR inout for VR, hall, and even EDIS.

Generally, I find R52 can be left on the default fully anti-clock position.

R56 usually ends up about 6-8 turns clockwise.

It's much easier to adjust R56 with a scope connected to VR out. You set R56 for a decent square wave of approx 5v peak to peak and an even mark/space ratio.




Top trace is VR out with that scope input set to 5v per division
Bottom is VR in """""""""""""""""""""""""""""""""""""""1v"""""""""""""""

Thanks a-lot, got it right I think
will start the engine shortly
