LZ9/3900 swap into any vehicle questions
I would like to see a good summary/recent status on what it will take to put a LZ9/3900 engine system into an older OBDII or OBDI vehicle.
I've Googled just about every combination of word strings relating to LZ9 engines and GMLAN control systems and it seems like very few enthusiasts are having much success putting any current generation GM engine into pre-2006 vehicles.
It seems like VVT, variable length manifolds and GM power management systems are not being controlled yet by after-market systems, and the engines don't run right unless they have all of the GMLAN modules in place. PCM, ABS, BCM. All of the 3900 swaps I've read about are removing the VVT, intake manifold and turning off or removing the power management features. I would really like to be able to purchase an engine/transaxle from a wrecking yard and be able to drop it in as-is without having to modify the engine. If I knew how to handle all of the BCM (Body control module signals) that talk to the (PCN) Engine/transmission control module, I could handle reworking a new harness.
Questions:
1. Where can I find out more about GMLAN High speed dual wire CAN, and the single wire CAN data busses?
2. Have the codes been mapped out yet by someone?
3. I read a little blurb that someone is trying to create software where you install a small industrial type PC in your car where all of the older OBDI/II sensor signals are inputted to the PC and then the PC mimics and converts the signals to the CAN signals and it talks to the (PCM) Powertrain control module. The PC interfaces to the data link and lets you monitor all of the data and/or lets you tune the car and display everything on a touchscreen monitor. Has anyone else read about this or have more information?
4. Are there any after-market systems for sale that play well with GMLAN?
Thanks.
Joe
