Ok so I'm currently running the 123ignition dist on my 2056 with dual webers. I read the instructions and don't understand the mapping. I also don't know how it all works together. Can someone educate me on the vacuum adv and what curve would be best? As the rpm's increase it creates more vacuum thus creating more adv, but if I already have a curve setup to go from 12 degrees at idle to 28 degrees at 3000+ will the vacuum adv move the timing even higher once it is hooked up and mapped?

So Mike, I will be installing mine soon, right after I get motor back in the car and have it running. Once I do that I will put this in, I just don't want too many variables at once, - but to clarify, when you had the d-jet stuff on your motor you ran which curve setting on the 123 dizzy?

Phil I'm running curve "B," Phil. 2056, D-Jet. My experience is similar to Mike's. When I tried to run vacuum advance I couldn't get the idle low enough. Vacuum advance works over a short range from idle, and my performance is just fine. |
