Does anyone have a wiring diagram to follow to help me with wiring a vr ecu plug in to a vu thanks :turbo:

Only the factory one's for each harness not a guide as such.
Quite involved. If I was to do it I'd want a harness from each. Mainly for extra plugs snd routing.
Not impossible just time consuming. Factory diagrams are in the wiring section.

What's the need for the buick in the VU? Speedway?

Im looking at running the vu eco engine on a buick/e6gmx ecu so i can get away from the factory maf.. there is only one tuner in town with limited ability a vu to vr patch loom would be ideal

Id find another tuner. The MAFis not a restriction. There's a thread on here with someone making a VT to VY patch loom.
Lots of hour's it would cost you a few hundred. You could possibly run the ecotec straight off a VR harness?
The VU ecu is tuneable with the MAF.
