M2000 S4 Wiring Diagram

Hi All!

Disclaimer: I know Adaptronic is dead, but I'm helping a friend out.

I'm helping a friend wire an M2000 into an S4 Rx7 with factory coils, CAS, and ITB's. I've wired in several Haltech's, but I'm finding conflicting information on wiring in the Adaptronic. Primarily as it relates to the factory coil wiring, RPM limits, tach, and the CAS wiring. Are there any wiring diagrams for this setup floating around that I couldn't find by searching? I found the main pin out diagram, but could use some assistance.

Is there an RPM limit in wasted spark for factory coils and if so, how can this be bypassed aside from IGN1's? I assume this engine will be revved to ~9k.

Any help greatly appreciated!

Hi! I hope you've made some progress.

If you haven't found any data, I'd suggest checking the pinout diagram of the plug-and-play ECU for the FC-S4 and transferring the connections. The CAS interprets it as a 24-tooth gear. In the EUGENE software, you'll find each pinout in the wiring section.

If you need any further documentation, I'm trying to gather it here>> https://github.com/X-ELE/Adaptronic_archive/
