Control sti dccd center diff with a pdm output?

[mavericka70]

Hello, im still learning electronics. I have a link g4x installed in an 04 sti swapped gc, and I was thinking about using it to control the center diff. It's my understanding that the diff locks with a constant current 0-7v for locking % instead of just a pwm circuit. Is this something a pdm would be able to do better than just a ssr? I was thinking about getting one for the car anyway. Thanks!

Yes, it is possible to current control an electronic differential. You can use the PID control function to closed loop control output current. 
Target current can be output by the ECU. 
I write my own strategy with several GP PWM tables, GP function and maths, which incorporates Slip, steering angle, speed etc. with several driver adjustable tables. Driver can select separate braking and acceleration tables.

Awesome, that's what I was hoping to hear. Thanks!
