Ignition Thoughts/Ideas/Recommendations

[ROT8WA]

Erm, I'm not sure how you a running LS2 coils with a CDI box as the Ls2 coils have there own built in Ignitors. I thought that this type of coil would be a total miss match on a CDI system?

Other than that, I have personally replaced a MSD CDI system (6AL) with LS2 coils with a significant reduction in misfires and power increase of about 15 Hp (400ish horsepower N/A V8).

Strangely, I too found the CDI to misfire significantly more at idle (as TTT found).

All I want is enough ignition energy to light the air/fuel charge in my Naturally Aspirated Rotary until the VE decreases to the point that I might as well stop. I am expecting this to be between 9,000 and 10,000 RPM. I am reasonably confident that 120mJ of ignition energy will get the job done.

If every car was a Ferrari, I would be walking to work.

I just want something that is functional and inexpensive.

The LS2 coils appear to fit the bill.

I hope they do, because I have installed them on the car and will hopefully be starting it this weekend.
