Am here Colin, yeah I just finished my megasquirt plug in harness we will see shortly how the dizzy Mod works, the megasquirt will run on the stock dizzy no problem as long as u have 2 vr sensors on board your megasquirt, u can get a diy kit for the 2nd vr sensor, the dizzy Mod am doing uses 1 vr sensor, u grind out 2 teeth 180 degrees apart on your 24 toothed wheel, this will detect tdc as the cam rotates half the speed of the crank, a bit of wheel decoder settings in mega tune and other setting to associate tdc tooth, it should be good.
