KK GDI Posted February 3, 2019 Report Share Posted February 3, 2019 Hello there, I am working on setting up a Mitsubishi GDI engine with the Force GDI ECU. I am using the ICS servo (dual coil, with 2x2 Minus, and 2 Plus) at Aux 5,6,7,8. Now I am also wanted to connect my EGR system, which is also a servo with 4 signal wires and two coils. Any idea how I can connect this? Also -the purge valve -one On/of bypassvalve -one dutycycle bypassvalve are there to connect. Next thing (Maybe I will open another topic) is the construction of the High pressure Fuel pump. As far as I saw it, it is hardware controlled, and there is just a sensor to read the pressure. Am I able to use the ecu like that, without any pump valve connected? Quote Link to comment Share on other sites More sharing options...
Adamw Posted February 4, 2019 Report Share Posted February 4, 2019 Only Aux 5/6/7/8 are capable of stepper motor control. 4 hours ago, KK GDI said: Next thing (Maybe I will open another topic) is the construction of the High pressure Fuel pump.

That would be highly unusual although I have never seen the mitsubishi system. I would expect there would have to be some electronic means to control pressure.

KK GDI Posted February 4, 2019 Author Report Share Posted February 4, 2019 I allready used AUX 5 to 8. Is there any way to connect a second stepper motor with 4 pin connection? Electrical wiring GDI 98.xps Quote Link to comment Share on other sites More sharing options...
