jonbill wrote:you could set 'skip revolutions' to 3, then it wouldn't attempt to fire while it's inaccurate.It's alreay at 3. I tried 4 and 5 and same result.

What does it mean?When i start, the first ignition event is after tdc (around 5-10 degrees). The second is also after TDC. The third is on TDC and the following.

I had an issue with VR sensors that Honda used on my Goldwing FI system. The crank VR sensor was fine, but the VR sensors for the camshaft signal was not adequate for the Speeduino ECU (using the v0.4.4 board). Changed to Hall Effect sensors and the issue of sensor signals went away - don't have to use a VR conditioner.Yes, it's a solution but the problem is to find the hall sensor that will fit in hole of vr sensor. My vr sensor is into engine.
Maybe try a Hall effect sensor in place of the VR sensor. I use the Cherry GS100701 from Jameco - $38.00. Needs a 1K pull-up resistor but the resistor is already on the board. Maybe search for other users of the GM7X trigger pattern and read what they did for sensor(s). Sometimes making the old components work is more of a PITA than its worth.
Good luck.
