99+ LS1 PCM swap into OBS GMT400 trucks/SUV's

[Aloicious]

I am planning on swapping out my pcm when I do my 80-E swap. So now I have two options: Buy EFILive and learn how to tune it myself, or have Black Bear Performance tune it. Since I live not to far away from them I should probably take my 'hoe to them and have it tuned. I think it would be cheaper too. I just don't see the advantage of buying the whole software for a few tunes. As far as re-tunes go, Black Bear does them for free.

heh, its never 'just a few tunes', since I've got mine, I've litterally done hundreds of logs, and dozens (perhaps even hundreds) of tunes. but then again I'm extremely picky about stuff like that.

Yes, The 0411 PCM will plug into the other harness.

Here is one I found for $25 You could probably get them to ship it to you and be around $50 total, that will probably be less, but just one of those I found on http://www.car-part.com
If you cant figure it out just PM me with some details and I can get you a list.

i have another question, i still have yet to do my swap but i got a 411 out of an s10 blazer. the reason its not done yet is simpley because i dont know what step i need to take next without getting efi live or TC. i would like to just have the van tune for NOW and down the road get the efi set up. i have a dealer thats pretty friendly and a guy that has been working for gm for almost 30 years. so i have acess to people that can reflash it, my problem is i need to know what to tell them to reflash it to. i heard all i need is the vin number to a van with the right set up. i have the manual trans and 4 wheel drive and its for the 97. do i need to buy a vin number or somthing or just copy one down? im not sure please help me lol!

The dealership will not be able to help you. The 02 Express van has a different Evap system and was not available with a manual trans. You will need to have V.A.T.S. deleted. You either need to get tuning software or have somebody with tuning software set up your tune.

Unless you have an engine made for AFM control (the 4/8 cylinder mode stuff), just running the PCM won't work, there are mechanical issues as well. trust me, I've looked into it a bit. heh. grab a 411 and you're good.
