vr ecotech,again..

[202injected]

I know this question has probably been asked a thousand times before, but i am curious,

If i stick an ecotech into my VR and wire it up to all the VR(buick) sensors and wiring, will the delco run the engine?. i have compared both motors in complete form and most of the stuff is simiale and things like the firing order are all the same, only difference being as my VR is a manual it does not have the cam angle sensor (only autos did).
alternatively, will it run if i swapped the delco for a plug in haltech?

any help/opinions/comments please people

I think some of the sensors may throw out different readings between the VR and VS engines.

It would be interesting to see if you could get it go, I know one thing for sure, if you want to run the VS ecotec and keep your VR ecu you'll be keeping your map sensor and scrapping the VS MAF.

Other then that I hope someone like Kopper or Abba or about 300 other smarty pants come along.

It will run just fine on the stock tune, been done heaps of times on VR's, you need to get the map sensor on. One other sensor needs taping on (see hozys notes). And on the VR's the tps sensor wires need to be put on back to front if you are using the VS throttle body

one thing i'm interested in finding out... are ecotecs legal in earlier models without the MAF??? (mine would need to be engineered as I'm going turbo)

[greenfoam]

If you are going to run a turbo and get it engineered it will need to pass an emmisions test anyway and if it passes that whatever ecu was running it is legal. The test is emmisions test is 2 grand +. If you run straight lpg you get to skip the emmisions test.

Officialy un engineered/emmisions tested the map ecu on the ecotec isn't legal but it would easily pass the relivent ADR so it's not that big a deal, you wouldn't fail an emmisions test on the VR ecu. I'm a big greeny and I'd sleep easy at night with that setup, I figure if it's good enough for me good enough for the epa legal or not. It's morally OK and in the end that's the most important thing

up here we don't need emissions tests. from what i've been told the engineer simply looks at build quality, obviously they check that it'd pass EPA requirements like non venting catch-can etc (venting BOV's are legal so long as they're not excessively loud) and check that other things such as brakes are up to the task
