Ignition Module question.

[Zak's Z]

I just bought an ignition module off ebay for a 1979 280zx but when I got it it reads E12-93. I assume I needed the E12-80 to go with my zx distributor for the 240z electronic ignition conversion I wanted to do.

Can I use this module? What year is the E12-93 really from?

Any help is appreciated. I searched a bit and found some discussion that said you can use it but need a different vacuum advance possibly.

Thanks guys,

E12-93 is from a later ZX, 82-83, IIRC. It has a third terminal on the side. It will work, but will retard the timing unless you do the vacuum advance mod.

Thanks Arne.. what does the vacuum advance mod involve?

Not sure. I've never done it. I believe it requires a different vacuum assembly, and then a travel-limiting spacer be made and added. I think beandip has all the info.

Can't you just remove the E12-93 module, trash it and replace it with an E12-80? Doesn't the extra terminal on the E12-93 get a signal from the coil for a circuit that isn't needed on cars that don't have that circuit, like anything prior to 82?

Yes, Stephen, that's what I did. I found a couple E12-80s for next to nothing and actually gave my E12-93 away for free. I didn't want to mess with the mod. But I've heard that (in some parts of the country) E12-80s are hard to find. Not so, here out West. The wrecking yards are full of old 210s, 510s, 200SXs and pickups with the E12-80.

So if you can't find an E12-80, the advance mod should make the E12-93 work. But it does seem simpler to find the right thing from the start.

Ya, I'll find one then. Im just annoyed I got the wrong one. I'll try and sort it out with the seller, but I won't hold my breath. I jumped on it because it said it was '79, looked like the e12-80 in the pic and couldn't find one up here in Toronto. If anyone has one they wanna part with send me a pm!

Thanks for getting back to me guys.

Hell, I've got about 8 or 9 working E12-80 modules. I'll give you one for postage.
