has anyone to date ever utilized the MSII V3? i've been doing alot of reading on this unit and it seems like a great alternative to the aem ems/haltech unit.

I've looked over our cars MFI system through factory circuit diagrams, seems our stock injector/fuel pump/spark relays should work with the unit.

however im not to sure about our stock iac. The stock 4g94 IAC is a stepper motor style IAC. Does anyone have the voltage values vs. steps of the IAC, or the connector pin legend?

The MSII also allows full range spark advance tuning aswell, and supports ford's EDIS4 wasted spark ignition system. I'm very interested in this igniton systems, its cheap and effective. Would the 36-1 trigger disc fit behind our crank pulley?. Looks like there should be enough room back there...or one could machine out a 36-1 pattern on their rrm pulley...

any help/input would be appreciated

 

I've never heard of it. Can you link to some more information?
