Trond,

A few things.

To verify the trigger offset you need to make sure you set the upper right to "fixed timing". It can be difficult to find an advance value where the engine will run from idle up through 3K. Usually 15 deg BTDC will work.

If the timing still drifts with the fixed timing you need to adjust the "spark hardware latency". In this case, you will lock timing at low rpm. Then raise engine speed and check spark. increase the latency value until the timing matches at both places.

Usually a VR sensor has very low latency. You did not mention what sensor you are using. Is it the same sensor as you had with EDIS?

Regarding the ECU resets this is usually indicative of input power issues or ground connection issues. Did you use a fully shielded wire from the VR sensor all the way back to the ECU. The VR sensor puts out a lot of voltage at higher rpms. It can produce noise spikes that will interrupt power to the ECU. make sure you have quality shielding for a VR sensor. Also make sure the shield ground is only connected on one end. I usually ground at the ECU end, not the sensor end.
