Quick background. Engine is a rebuilt 2L with Elgin cam and Weber 40IDFs. I bought a Pertronix Ignitor 3 to avoid having to mess with points but I could only get it to work well with a NOS Bosch 050 distributor. It runs rough with a brand new Bosch clone SVDA and the OE dizzy. However, the engine runs best with the OE DVDA distributor so I'm running that with points.
The problem is that I've had to adjust dwell and timing 3 times in only 1,000 miles of driving. Each time the dwell creeps up until the engine starts spitting and farting and is a bit hard to start when warm. Readjusting the dwell and timing gets it running like a top again. So (IMG:style_emoticons/default/WTF.gif) Only thing I can think is that the phenolic block on the points is wearing crazy fast. I lubed the cam and block with high temp slicone grease and I can feel it is still on there. Did I just get a shitty set of points? |

I just happened to speak to a Pertronix rep this last week when trying to make a purchase decision on a 1.8L dizzy application. I got lucky to speak to surprisingly knowledgeable tech & a ACVW owner.
His comments were interesting. He said in our applications (ACVW in general & T4 specifically) for 90% of the owners he'd never recommend the purchase any of the III products. The II offerings (points replacement & dizzy's) were the best option. |

Given their reputation for shit customer service, I don’t want to install it if I’m guaranteed problems. So, anything more you can share would be great help… I can’t understand why they would list the v3 on their site for use on my car if it’s not gonna work, ya know? |

For posterity, I finally managed to get ahold of a Pertronix rep and he said that what they are seeing is that the Ignitor III doesn't seem to get along with fuel injection. That includes any aftermarket or Bosch system. They suspect something about the signal causes the multispark to get confused. Thus, the Ignitor III is only an option for carb conversions. Otherwise, the Ignitor II is the best option for the rest of us. |
