Yes, I made the conversion in my 97 GMC. I used an 02 LS1 converted to LS6 though but basically the same swap. You're from Germany huh? I'm german too but speak very little. Our last name was Von Merheim and changed over to Merrem when my grandparents came over to the states. Anyways enough there but it's a great swap and I can help you out with the wiring schematics. There's plenty of info at the top of LSX conversions to get you going.
John at Speartech swapped an LS2/6L80E setup into an '01 truck. You might want to check out his post. He can help you out with anything needed to make the swap work for the Tahoe. Most likely the easiest way to get it to work is to run the new pcm to control the engine/trans and keep the old pcm to control the gauges, a/c, etc...

Make sure to post up some pics of your progress. What engine/trans will you be running?
I'd ditch the old pcm and just rune the newer pcm, it will control everything the old PCM did. I'm running the 02 pcm alone and everything works like factory. You can run both, just alot of clutter. No disrespect 350ss, there's just easier ways.
I agree with what you're saying Nitrous, maybe I misunderstood the original question. I'm assuming that by GenIV he means an engine/trans combo that uses the newer E38 pcm that the signals for the gauges/ac control and other things are sent over the can bus. This means you wouldn't be able to use an '02 pcm that has the correct outputs to run gauges/ac/etc. If it's a GenIII motor then of course you can ditch the old black box pcm and run the newer styls ('02 for example) pcm...that's what I did too ;)Quote:

running the '02 ECM seems to be easier than what I intend to do. The engine I have choosen is a '07 RPO Code LMG, that's flex fuel and cast iron block. I try to run only the '07 ECU. I am swapping the 4L60E the same time and I opted for the following parts: engine + tranny, engine harness, ECU, Trans Control module w wiring, ETC pedal assembly, instrument cluster w wiring, fuel pump assembly w wiring. I like the thought of using the '07 instrument cluster with all its gauges and the driver information center. What might be missing is the BCM but i will try to dig this out.
I may have some trouble with the 2 CAN bus system but we will see. I am electronic engineer working for Bosch Rexroth over here so we will see how far it will get me. By the way I managed to get my hands on a complete set of wiring diagrams for that Tahoe..
You might try talking with Patrick (PSWired) over on the pacific audio performance board:
GM Performance :: View Forum - GM Performance Forum
He's putting a 5.3L (flexfuel and active fuel management) and 6L80E trans into his '95 Tahoe and is going to try to adapt the can bus system to his tahoe also. He's an EE as well so I'm sure you guys could help each other get this figured out without having to keep an older pcm to run the gauges etc...

Hey... good news.... thank you for that advice.... I will contact him soon
350ss, I didn't think about the CAN bus and E83, etc..... You're correct with what you said on the PCM. I talked with Patrick when I made my swap and he's a pretty straight up guy and knows what he's talking about. Here's an article that might help with some of the info your looking for.
Engine Swap - Wiring - Hot Rod Magazine
Yup, Patrick knows his stuff. He did his 6.0L/4L80E swap back in Dec of '04...not too many guys were doing this back then. Now it seems like everyone is getting in on the act. Nothing like riding the coattails of smarter people :) If these guys can make this work without having to retain the stock pcm, it would be a pretty big deal in my book.Quote:

Oh yes we will make it one or the other way.
Sad thing is that my engine and tranny package deal is more complicated than first expected. The company I odered from ( and already paid..!) has problems to source all the parts I want out of one truck / SUV. Good thing is, the guy who is processsing my order is a good one, he tries whatever he could to source all the parts. So after all arrives in germany the real "fun part" begins.
The more guys are starting with this kind of swap the more informations we will recieve and the quicker all the problems and headache disappear
hey, I am back
I had some headache with the first supplier of my engine tranny combo. Ok I had two long nights on the internet and I found a company who's more specialized in late model conversions. They keep all the wiring and all control moduls and the guy I was talking to knew his job inside out.
Here are some pics of the combo I bought. I also opted for the under dash wiring and the BCM. We will see when all is here in Germany.
here are all the parts I bought for my conversion:
5.3 engine with ECU all sensors( incl Mass Airflow and O2 sensors)
wiring harness
exhaust manifolds, starter, alternator, steering pump,
AC Compressor ,accessory belt, fuse / relais box
4L60E transmission with transmission control module and wiring
Body Control Modul (BCM) with wiring
drive by wire ETC pedal assembly and wiring
instrument cluster and wiring
fuel pump assembly with pressure sensor and wiring
single stainless fuel line incl filter from tank to engine
You know, the more I thought about this why would you want to use the can bus for the gauges unless you're going to try and put the newer cluster in your 97? To make everything simple you could still use the GenIII sensors and hook them directly to the 97 gauges. You already have the wiring from the 97 harness and you just need to hook the sensors up. Just a thought if you were to run into problems. It would be like all my gauges and sensors are hooked up, standalone from the pcm. Let us know how things work out for you and what issues there are with the can bus, I'm pretty interested in hearing about it.
Thanks
