Not unless you reprogram it, one to remove the VATS, and 2 because they are different spec motors - sequential injection & roller cam in the VT, vs batch fire & flat tappet cam in VN-VS.

But it is possible to reprogram computer to run sequential injection on vr/vs motor after changing to sequential injectors???

You also need to change the cam, or have someone re-tune it, as the sequential motors ran a different cam with roller lifters.
Im assuming from your username, that this is probably going to be a conversion into an earlier model??
Fow what its worth, if youre doing a conversion, hunt down a VN-VP V8 loom & ECU. It will work on all VN-VS engines (may need the 3-pin distributor plug changed) with no anti-theft hassles that the VR, VS & VT have, and if youre running a hydraulic Turbo 700, turbo 350 etc, or a manual box, it will be far better.
You would only bother with a VR-VS-VT computer & loom from an auto if you wanted to run the 4L60E electronic auto behind it, and you had the complete conversion from the one donor vehicle.

VR-mid VS (or thereabouts) manual ECUs are pretty much the same thing as VN-VP ECUs. With a TH400 youd want to run a manual ECU anyway.

The only real improvement in the VR/VS computers is that they do have a bit more speed (like a newer PC compared to an old one) but the VN/VP is just as good for tuning, with no lack of resolution points on the maps.
For ease of searching, and not having to remove the VATS, Id use a VN/VP loom & ECU (auto/manual doesnt matter) for your conversion.

Im with Mick.
The VN/VP has the same tuning capability. The only real difference is the communication speed (baud rate) at the diagnostic connector. After all, they are only fuel & ignition maps. All your a/cond, engine cooling fans & other gear will all work with the same, whether its a VT or a VN ECU.
A VN/VP ECU will work with any transmission (man or auto) except an electronic auto & are in plentiful supply. Not to mention the lack of any VATS (security) to get in the way of your conversion to an older model car.
I have carried out several of these conversions & the VN/VP is the simpler & easier way to go.
