My first ignitor was a Hot Spark, It looks and acts just like the Pertronix unit with the small magnet ring. Worked fine until I had a small melt down, not the hot sparks fault (IMG:style_emoticons/default/biggrin.gif) . What I had noticed since I use the megasquirt, and put my scope meter on it to confirm, is during cranking i never got a nice clean square wave signal out of it. Once started , it was fine. This time I opted for the Compu fire conversion, since this has a large disk that passes over the top of the sensor. The disk has small magnets on the outside edge, allowing a higher surface speed over the sensor. Cranking signal has cleaned up by a factor of 2 to 1. My idle is now way more solid than with the little ring magnet sensor type of pickup. So, in conclusion, the signal coming from the Compu-fire is much cleaner, allowing better idle control for my application. 2 weeks in so far. I obviously can not attest to longevity yet.
Either one IMO works well for carbs, or stock FI, but so far, I prefer the compufire for my aftermarket FI. Attached thumbnail(s)  Attached image(s)

I'll check the part number when I get home. A guy in LA doing VW stuff was 62.00 dollars for it and got it in two days. The local shops up here were 120 and 99 dollars.

Oops 63.95 Powerhaus 310-328-2746 John I just got the one for the 050 dist, fits fine, just be careful how you route the wires around the advance plate. |
