VR PCM '424 into VT VX VY V6

Postby L67PSI » Wed Jul 24, 2019 10:30 pm

Hi all,

I've been thinking about this for a while so decided to make this post. Say I was to wire in a VR V6 auto PCM '424 into a VT VX or VY V6 Auto. Could I get it talking to the factory dash? What other issues could arise? I assume it would revert back to batch fire injection.

Only thinking about this as a MAFless option.

Would like to hear your feedback or suggestions.

Thanks

I realize it's been done before, but looking at what issues would need to be overcome. I did a search but couldn't come up with any specific info.

One thing would be to swap to a single Buick VN VP VR knock sensor.
