So my bulletproof died while on my way to the local car show. I pulled the cap off and everything looked good, clean and tight. So I'm assuming its the ignition module as I have never replaced this part yet in the last 22 years I've been driving this car. It's an 86 GT with a 4 speed. My question is has anyone ever tried the "85-88 V6 PERTRONIX PERFORMANCE CONTROL MODULE" offered at the Fiero Store? I've heard that you should only use the AC Delco module but the Pertronix claims more high RPM voltage as well as lower heat build up.

Thanks for your opinions.

got boost? L67 in progress...

Youve had unbelievable luck. Longest I had one last was like 4 years or so. I buy cheapo Autozone myself. Like $25 with free lifetime replacement. I got 2 more while I owned the car. Make sure there hot when they test or they will show good. Some say use only AC, so I took a try once and it quit in 2 weeks @ $85 and tough luck from dealer,

not sure if a "performance" module would actually do anything for real - but, if its not over $50 - go for it
I havent seen any real difference in modules - they all seem to last just the same: if your cars eats 'em - it'll eat any of them - no matter what brand.

You know...I've been thinking about why they fail.....I dont think heat is it entirely...I bought one from the fiero store and it didnt last a year...after only putting 2000 miles on it. There has to be a good explaination...are they just built that crappy? Has any one taken one apart to find out what componet actualy failed. Does anyone know whats inside them...?

I think moisture has a definate effect. 2 of the ones that failed on me were after a long, several hundred mile drives in pouring rain. The last one hadnt failed before I sold the car after i put a ' 0 ' ring seal around the module connector on the side of distributor.

Thanks to everyone that replied. I ordered the AC Delco from the Fiero Store this morning.

Anything I need to know to replace this part? Do I need new O- rings? Did everyone that had a failed module use dielectric grease?

Thanks in advance

You don't need an o-ring unless you pull the dist out.

I know many have have said they fail said they had used the grease. Just FYI there are two kinds of grease.
Di-electric which us used for sprak plug boot and plugs to keep water out and prevent corrotion.
And heat sink grease which is for heat transfer and should be used on the modules.
The heat sink is usually white and the die looks more like silicone and is somewhat clear.

If people are using di-electric grease instead of heat sink that could be one reason the module might fail. Their not the same thing.....

Heatsink - http://www.intek-uk.com/TCGheatdata.htm

And DO NOT TOUCH YOUR EYE with HS grease on your finger, that's very bad....Silicone Dioxide..

Awesome! Thanks for sharing that with everyone...

before i even read this post or any of its replys, the only moduals you should put in there are either one from a junkyard (with gm inprinted on it), or one directly from a gm dealership....no porformance modual will hold up after a month or so...expecially from the fiero store.....

I'm running Borg/Werner premiums from Oreily's in two Fieros. One (88) has over two years on it without any problems.
They (Oreily's) sell a standard module and a Premium for a few bucks more. The Premium are tested to a high standard.
I didn't know about these until the counter guy told me about them. Wonder if other brands do this.
That maybe the case with the AC's they are just the better run of module.

Not to hi-jack a thread but I used ot own an 88 silver Formula. They are pretty uncommon, where and when did you get yours, feel free to PM.

To the comment, I too like junkyard parts because they are cheap and you can keep 2 or 3 in the (FRONT trunk, where it's cool) for spares. I haven't been left on the road side since.

Just to be clear, I didnt mean the distributor shaft ' 0 ' ring. I mean I got a bigger ' 0 ' ring and put it in the groove that goes around the module connector with half in the dist base and half in the cap so that it was effecting a seal around that connector when the cap was installed.
