Re: Car is running Fantastic
I can’t tell exactly... is the factory ICM connected to anything?

Re: Car is running Fantastic
Very nice work Jeff.
Really like the way you made the coils fit in the valley area. Great job. Pete

I have been in contact with the designer/developer and it sounds like there could be potential that he makes more, I had bought his last two, knowing they might not work. Quote:

Re: Car is running Fantastic
Jeff,
Do u have pics of the trigger harness for the coils? And did u use the existing power circuit to energize the coils? When I did this conversion, but using the stock ICM, I needed to use a separate circuit to energize the coils given that our stock circuit is only 10A IIRC.

So I used a relay to power the coils with a 15 or 20A fuse.. yeah the wires run to the front of the car, but the circuit was already there and no longer used since I removed the A.I.R. pump.

Re: Car is running Fantastic
Jeff,
Is dwell configurable? LSx coils throw a hotter spark and part of that is w 8 coils they can dwell longer. I’m assuming u re-gapped plugs.
