Haltech IQ3 in an FD
Cool, well I've actually got friend who is an electrician and circuit guru to reverse engineer the original Mazda system.... Hopefully he will get me some info and finalise the parts he will need in a few days. So I'll keep you all posted
So BM .... You gonna try and run the msd box from the tranny sensor? ....

So I wired my sensor directly to the haltech as per Fritts instructions, and downloaded a GPS app to my phone and with a setting of 8230 in the haltech speed settings I'm 0.5 mph difference between the dash and my app att all speeds



... as i undertand it the sppedo sensor on the tranny sends two signals to the OEM dash which has a built in comparator/ converter within it.... this then converts it to a digital signal which goes to the ECU
