Hi!

I'm running my coil directly with vb921, but I have problems to set good dwell time. with 3 ms it is okay but my v3 case gets warm (38 celsius degrees) after short run. With 2,5ms I get weak spark but no heat.

I think I need more tha 3ms to get best result, but then whole ms will probably melt.. any ideas?

What should I set to maximun spark duration? My engine has redline somewhere near 6500.

Hmm.. maybe I have to try decrease dwell time step by step with 0,1ms and use max spark duration 2.0ms, that should be enough?
