8.1 L VORTEC

belgiumastro · September 16, 2005

Hallo, I need a ecm for a 8.1 vortec engine, this ecm must be from 2001 and work with the 40L80-e transmission(rwd). I need this because I have a 8.1 crate engine that will be on a 67 buick riviera. I want that the engine works like on Your trucks, and because there gonne be a Kenne-Bell supercharger on it. Its also possible to buy a ecm by autoparts but then do I need a VIN number with this specifications, so it can be reflaching.

I also need the transmission and wiring harness, so maybe somebody knows a wreck??

Thanks

Carl

Trying to find one for an 8.1 and 4l80 would be hard. All pickup 8.1 use the allison. I think the suburban 8.1 still use the 4l80.

I would contact one of the many tunners mentioned/sponsors on this site. They can tell you or even sell you the correct pcm. You will need the new pcm tunned for your application anyway.

i think the pcm from any 01-02 will work, it doesnt have to be the pickup one but i think it can be the ecm off a 2001 5.3 4l60e for example, im not sure about this but im sure any of the tuners have them for under 200 bucks

I have talked with Jessie (wait4me) and Nelson. both seemed very knowledgable. I know Jessie makes entire harness for street rods to go with the pcm. I had no trouble reaching him a few month ago but lately his customer service has left a lot to be disired. Phone seems to be the best way. I reached Nelson (looking for an e-fan harness) by e-mail. He responded the next day.

Shoot some e-mails off and see who responds.
