Quick correction: the megajolt only uses a 36-1 trigger wheel which isn't compatible with my distributor parts. I've only used the megasquirt and assumed (my bad) megajolt was just the spark side of a megasquirt, but in reality the megajolt is only compatible with EDIS and might not get you to twin spark... not sure if the "SAW" signal can be paralleled to two EDIS controllers for the second set of plugs and coil pack. That's be a pretty cluttered setup anyway.
For twin spark on a megsquirt based system you would parallel the logic level coil fire signals from the megasquirt to the two VW 2.0 coil packs ($30 each new on ebay). Haven't set this system up myself (don't have the heads), but there's no reason it couldn't be done that way. |

Haven't set this system up myself (don't have the heads), but there's no reason it couldn't be done that way. For a twin plug 4-cyl setup, you could use your trigger system with an arduino beetle (the size of a quarter, it would fit in the cap) and it would send your timing pulse to two separate MSD DIS-4s. The Arduino would delay the timing pulse to the second MSD with a adjustable duration that would determine the spacing between the plug firings. Both MSDs would drive 4 coil on Plugs. |
