I'm not using EDIS. The smart guys over at the MSEFI forums wrote code to decode Nippon Denso style 12 + 2 trigger wheels. They also allowed for 6 spark outputs on the MS 1 chip. I have a V3 board with the V3 VR conditioner for the stock crank sensor, and I built a LM1815n circuit in the prototype area for the rear cam sensor. Dropping one cam sensor allows for a trigger ever 720 degrees of crankshaft rotation which configures the MS to directly fire 6 coils in sequential fashion. This is why having one cam sensor is important.

Since I don't have EDIS, I can now control spark in other ways such as a spark cut rev limiter and spark cut with retard staging limiter (which is great fun).

Bowling and Grippo will be introducing the router board which will allow for sequential injection and ignition with the MS 2, but until then, I'll stick with
ms 1.
