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?

Not that I run carbs......I run D-jet.
In my opinion this is one of the better upgrades for drive ability that I have done to my car. Once your AFR is right it is set and forget. FWIW I do run the vacuum advance, but my car runs the stock cam and injection so I went with a different dizzy. Bluetooth is not available for the D-jet version. |
