My project is a little different, it's an 18' speedboat which was converted from its original engine to a rover V8 (it looks like from range rover going by the timing cover).
It was using strombergs and a dizzy with luminition fitted.
At some point with the previous owner it had overheated and broken some rings so I've built a fresh engine but because I'm partial to big ideas that I don't have time for I decided to modernise the installation with old fashion 14CUX fuel injection, a trigger wheel + VR sensor from a Gems engine, coil packs from a Thor engine (Bosch) and a nodiz (which I think I've just managed to blow up) to run the ignition system.
As trying to do all this in the engine bay of the boat would be virtually impossible I've made an frame to run the engine in from the comfort of my garage. Unfortunately I lost one of the coil returns and soon after whilst fault finding the nodiz gave up altogether.
More head scratching now and maybe a call to Motorsport Electronics.
That's an interesting sounding project, always good to hear of something a little different.
How are you feeding the ignition pulse to the 14CUX? I've ended up with a diode on each coil which seems to be the default way of doing this.
I'm running the GEMS coils, I think the Bosch/Thor were later but similar if I've understood correctly. They run fine now with the Megasquirt so there's not a problem with them but possibly Nodiz didn't like them
Strange that you could have popped the Nodiz as the coil connections only supply a ground, hard to imagine what you could have put in there which would overload it.
Good luck getting it sorted.
Are you hooking up to a computer or setting up just with the buttons?
