wiring in a SAFC and AVCR question

[bioskyline]

got the VPC and SAFC all wiried in, now i got a AVCR in the mix.

been looking though the digrams and as its a dual grounded unit, do i have to ground them into the ecu wireing? or can i just body ground them?

You need to ground it into the ECU wiring, and be sure you attach the grounds 1/4" apart so you don't wind up with the different devices grounding to each other rather than the ECU.

ok thanks

If all 3 are grouned to the ecu ground does that also mean all 3 need the power from the ecu power wire also? Or no?

 

[bioskyline]

correct

That's how I wired mine. It's been working fine, no weird voltage readings or problems.

I only wired in the AFC Neo though. It doesn't draw much power, I don't know if the ECU wiring is heavy enough to run a VPC too. The boost controller you can just wire to a clean chassis ground and power it from the ignition switch.

I've seen/worked on cars with so much alphabet soup connected to the wiring harness it's ridiculous. You can run a VPC, GCC, AVC-R and S-AFC and anything else you want at the same time without issue.

The boost controller you can just wire to a clean chassis ground and power it from the ignition switch.

Remember, the AVC-R isn't your average boost controller. It's RPM and "gear aware" and needs inputs from the ECU.

they power up, and my car still starts! tommorow to mount the selanoid and sensor for the controller.
