MS has a stepper motor control for idle now in MS2. I "think" it can also trigger spark using the two crank position sensors in the stock dizzy - have to check the input signal to the ecu for compatibility.


Yes, the IAC can be controlled by MS now, but I see no provision for A/C or P/S signal input - nor do I see any control for idle speed monitoring/adjustment - only a coolant temperature stepper value for cold start. There's probably a way to introduce a switched electrical value for P/S and A/C stepper control, but I haven't seen it addressed in any of what I've found so far.

Yes, the optical CAS and trigger wheel in the OE distributor will work with MS2 v3.0 boards and allow the SOHC distributor to fire the OE single coil.... very tempting for sake of simplicity.... the 5v trigger appears to need nothing except a board jumper and correct wiring.

Re the fuel rail, why fool with it? Look at the captive injector bungs on the SDS site, combined with whatever size hose you need for the flow you require, and junk the stock fuel rail, which, after your experience with it, should be a lot of fun.


Thanks - just looked at those - they look promising.
