GC8 WRX + GEMS and System 2c

I have recently 'aquired' :smile: a System 2c, does anyone have any knowledge regarding connecting it up to the GEMS ECU?

Hi, I've got my system 1s connected to the VTEC output of my Omex 700 which is a Gems EM36 ECU. The water injection comes on when on boost above certain RPM. I did not fit this myself as I got a company to do this for me when they fitted the ECU and supercharger to my car. I belive it just connects to the system 1s by grounding the pressure switch input to the pump.

Hope this helps

All you need to do is to connect the PWM output from the GEM to the HSV (high speed valve) of the 2c.

The coil resistance is 13ohm, it draws approximately 1Amp.
