E6X with IGN 1A Coils Compatability

Postby vcs2340 » Thu May 21, 2020 10:36 pm


I am running an E6X with 4 IGN 1A coils with wasted spark.
Coils 1 and 4 are wired together to the ignition 1 wire and coils 2 and 3 are wired together to the ignition 2 wire. The engine runs pretty well and has been on the dyno for a tune however one of the coils melted down during idle a few weeks ago. I got a new IGN 1A coil and the dealer suggested that I check the voltage on the trigger wires coming from the haltech and if there was zero volts with key on engine off I would be good to go. I checked and found 11.5 volts at the trigger wires for both sets of coils.

I talked with the tuner who setup the program and he said,
it is set to constant dwell of 3.5 msec right now to try and no overheat the coil.

I have been reading though the forum a bit and have not see a post about this issue. I read that a lot of people are using the ls1 coils, not sure if that would solve my issue.

Is there a different setting in the software I could use so my coils do not over heat?

Let me know if you need more info.
The setup is on a BMW E30 with a turbo M10 engine.

Thank you for your time,

Spencer V.

Make sure you have the right spark edge setting. Either rising or falling. The wrong one will fry your coils in short order. Ask me how I know that...
