CMSport Posted October 22, 2017 Report Share Posted October 22, 2017 Hey guys, I'm rather impressed with the amount of information on this forum and have so far managed to answer all my questions from the search function so thanks all however, this one doesn't seem to have been covered.. I'm throwing out the distributed spark setup on my little Daihatsu Charade 3 cyl and upgrading to a set of Toyota/Denso COP sticks (keeping with the 24 - 1 tooth cam triggers in the process, hopefully that will still work ok??) and wondering if I can just ignore the IGN feedback pin, labelled "ICMB" on the attached diagram? My assumption is that this is merely a feedback loop for the ECU to say that all is OK and ready to fire but I can't find any specifics on the internal wiring of the igniter to confirm this. Any help would be appreciated! Cheers Tim Quote Link to comment Share on other sites More sharing options...
Adamw Posted October 22, 2017 Report Share Posted October 22, 2017 Correct, no aftermarket ECUs use the feedback pin, commonly called ICMB or IGF. Just 3 wires needed to each coil. Quote Link to comment Share on other sites More sharing options...
CMSport Posted October 22, 2017 Author Report Share Posted October 22, 2017 Thanks for that, I was hoping that would be the case! Cheers Quote Link to comment Share on other sites More sharing options...
