Yes that's an option too. Seems simpler but won't reveal if the issue is in the electric side of the set up or not, a stock CDi or an MSD enhancer is much more forgiving.
My MSD worked with my TBM flywheel but as soon as I installed the HX3 I had issues so that told me it must be the HX3 since ski was fine prior but after 2 months of being down that want the case, it was that flywheel. Chris at Airtime diag this.....
Are you the original purchaser within the 90 day exchange period?
I guess installing a stock CDi would help some though, if the issue still remains you got other issues too, if it does work you could ride but you still won't know if it's the HX3 or your set up.
If a stock CDi works in your ski and your HX3 works in my ski what's that reveal?
Edit: ^^ this is more of an example of what I'am talking about rather than a question
