About 4 weeks ago I bought a Compufire DIS-IX for my baja. 1915, W120 cam and Kadrons. Not just the points replacement unit, but the whole shebang with module on top of the dizzy, coils, the whole thing. I fitted it, used Iridium plugs set properly, and it ran perfectly. Took a bit to get the timing right, but eventually it ran sweetly. Lots of grunt and no breakdowns right through to 6,000rpm. Then the trouble started.
After about 500kms or so and 5 hours from home, it started breaking down and eventually would only fire on 2 cylinders. Luckily it was 2 and 4 and so I was able to limp home slowly. I replaced the coil pack - no fix. Replaced the module on the dizzzy and we're back in business! Another 500kms or so and half way between Anna Bay and Lavis Lane on Stockton, it breaks down again! Not happy! Managed to limp off the sand and home. Now I am getting a complete new unit out of the box to replace, which I hope will work!
Has anyone had experience with Compufires? Found similar problems? If so, did you manage to fix it and what was the fix? I've checked voltage supply - good. Earthing - good. Heat - no heat problems that I can see.
I'm at a bit of a loss as to what's going wrong and will be fitting the replacement with some trepidation. The last thing I want is more breakdowns on the way to Valla in a couple of weeks!
Any help/advice would be appreciated.
Thanks,
Marc.

Hmmm, feedback not good so far, eh? Thanks Johnny and Craig.
Lee, it doesn't use the normal coil, has a twin coil pack that is all part of the kit. I had a Pertronix points replacement unit on it before this and whilst it worked great, I (perhaps stupidly) went for something that I hoped would give better spark, hence burn, hence grunt....
Cheers,
Marc.

If Your engine starts first time every time...
then You have a good spark lol
I have the Pertronix in a New aircooled SVDA Distributor...
and the spark is fine and starts most times at first kick
BUT
I had a home built High Energy Ignition System in My beetle for a while and it started the engine First Time Every time...
until the points wore down and the rubbing block twisted and shorted it out.... and ZAP....
[they weren't bosch points]
the actual points surface was like new as very low voltage went thru the points...
The HEI put 32 volts into the coil... [3 ohm coil]
so, thats why it was so good...

i had one. no probs at all.
and one thing the disX has its own coil, well twin coil pack.
i do have a new one but not for the old motor, its on
my new engine ready to go.👍
Compufire that I put on in the thread above lasted a couple of thousand k's only, then let me down on Stockton. Went to a crank fired EDIS Ford system.... bloody brilliant! Controlled with a Megajolt computer. Am now going to EFI so I need a computer for that, so I've got a megasquirt all ready to go when the EFI parts arrive. It can do the injection AND the EDIS ignition. No distributor at all now. Rock solid, programmable timing!
Cheers, Marc.
