What's your battery voltage with engine running? If you are getting wrong voltage readings you may get huge dwell times that burn your coilpack. Also check ground wire for coilpack. EMU and coilpack grounds must be bolted to the same point at engine block.

I had the EMU wiring loom fitted by the mapper. I'll ask him how was is wired up.
Thanks for your reply.
