Re: Distributorless ignition using GEMS coils and Hotwire system
It's the older 4 CU I'm more familiar with. It also has the external 6800 0hm series resistor in the coil connection to ECU. And with that removed, the 4CU triggers happily from a 5v signal. But seems the 14 CUX is different. This was one of those "suck it and see" problems for me, fortunately the ...

Re: Distributorless ignition using GEMS coils and Hotwire system
I'm using a diode pack from the coils supplied by 'Trigger wheels' to signal the 14CUX, I've seen mention of a resistor utilised inline but mine seems fine without (for now anyway). The nodiz which will be heading back to ME for repairs/renewal (after speaking to a very helpful chap called Edwin) an...

Re: Distributorless ignition using GEMS coils and Hotwire system
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 broke...

Re: Distributorless ignition using GEMS coils and Hotwire system
Thanks, I've got my head round that one now. My engine fired up and ran nicely for the first time yesterday ( big relief after spending ages mucking about with it), now I need to start looking at the value of connecting the other inputs the nodiz can take.

Re: Distributorless ignition using GEMS coils and Hotwire system
Hi, as the Nodiz is a wasted spark coil driver does this mean if all four coil negs are connected to the 14CUX it will see twice as many signals as required as does as timing light with advance/retard dial in ?
