Modified mine for use with SPE40 using Champion RCJ6Y spark plug. Bench test ran OK. I am going to the field to test it out today.
Sorry what did you mod?
I modified the spark plug cap. The cdi came with small cap for CM-6 plug whereas SPE 40 is using RCJ6Y which is bigger.
To be more precise, I actually opened up the small cap and replaced it with the stock SPE 40 plug cap.
Flew it this afternoon, it was initially having some interference and not running smoothly due to poor contact of the plug cap with the spark plug's hex head. The problem was temporary solved in the field by tightening it with a cable tie, and the engine ran smoothly after that.
The sad thing was: I crashed my plane due to human error...sob...sob....
