1.8l coil with integrated ignitors
 

After chatting with Nathan M-ED about his coil reliability, he said he's had no problems setting the Dwell to ~2.2ms. He's only blown 1 set due to a firmware upgrade, so he recommends disconnecting the coils when upgrading the firmware or changing any settings and reconnecting it only when everything is set up. Hope that helps, all credit to Nathan, I just wanted to post it here for reference.

I don't see why he needed VB921's with the 1.8L coils. They have intergrated ignitors. Where did you post his settings?

That was my mistake with the VB921s, I must've got his and my setup mixed up. His msq file is on the megasquirt forums under success stories.
