CB Performance programmable ignition timing BlackBox - 09/19/14 10:59 PM
Was wondering if anyone else here is running one of these?

I've just installed one in my Dart to be able to finetune the ignition advance curve.
Stock Mopar distributors are a pain to change the ignition's timing curve on so I wanted to try a modern and easy to tune, digital approach.
Originally made for 4 cyl. VW bug engines, the control box also works with engines upto 8 cylinders. The BlackBox comes will a fairly simple (Windows) program where you can set some baseline limits and enter your preferred timing curve with. There's also a vacuum input on the control unit to take account for engine load.
You have to run a locked mechanical advance in your distributor and no vacuum advance hooked up to it, because this is now handled by the new ignition box.
Upto today I was using a Mopar chrome ECU with a Blaster 2 coil and a stock distributor with a modified advance curve.
As I was always wondering if some more power could be found in certain RPM-areas I decided to get one of these ignition control boxes and have a go at it.
There are a number of ways to connect the BlackBox to the current ignition system. I chose to let the BlackBox control the coil directly and bypassing the Mopar ECU, but I think I'm noticing a lack of spark-energy from the perhaps longer dwell of the Mopar Chrome box.
Will try to do a rewire tomorrow to see if I can keep the Mopar ECU in the loop.
