These specs are pulled from a thread on diesel place.What's the size on the gm-8?
Could I just would like to try not to, looks like 2.5 pipes will fit with some creative routing.Could you modify the firewall to make more room?
Actually, they do, but it's just between the dlc, ECM, TCM and gpcm. But as Ken has mentioned related to GM and their message changes, the LBZ ECM may be missing some messages your cars modules are looking for. The 04-05 LLY's had a similar J1939 bus that was only between modules and didn't extend to the dlc.LBZ never had GMLAN communications bus. But kinda yes, what needs to be done is modify a LMM file to be the same as a LBZ manual file, somehow its possible just beyond my knowledge. Kory did say today that he would be able to "soon"

Ken would probably know off the bat, I don't recall if they have the same messages or not. I could put things back together on the bench and do some bus logging and compare to see.I wonder if the LBZ bus would send or receive any of the same messages LMM does.
Is it hard to log messages? What hardware is needed?Ken would probably know off the bat, I don't recall if they have the same messages or not. I could put things back together on the bench and do some bus logging and compare to see.
Thank youI was talking to Ken about some CAN stuff last week, and he told me to get one of these to record the CAN messages.
Thanks for the great info as always Ken. Sounds like by the time I’ll need this file Kory might be able to do it for me (car is parked now for the winter ) For whatever it’s worth I’ve reached out to some tuners about it and most of them have no idea where to start and the odd couple that said “ya no problem” don’t actually understand what needs done lol. Regardless I’ve got lots of time to get the rest done and can worry about the ecm stuff later.Back from my week of digging for $ in the sand. Got a tan, but no treasure..
The LBZ HS GMLAN shares "most" of the same raw CANbus messages as the LMM. Yet is missing some signals ya probably want, like OilPressure. Some others are Short a byte, which plays havoc with other nodes looking for 8 byte message, and getting a 7.. Weird stuff, like they just didn't get around to finishing the code before production time. So it makes it tricky when you try to run the LBZ ECM against 08 or newer chassis.
The LMM on the other hand, shares about everything CANbus message related with an E38/E67, making far easier swapping into 05-14 gasser chassis. LBZ was the first shot at moving away from J1939 to GMLAN protocol, on the new Bosch hardware and Allison TCM. Following year, they had it sorted.
I also dug up that :LMM bin file I've use as the marine swap base. It doesn't have that Standard Transmission switch, or options to change the CANbus VSS input to TOS line as I previously thought. I was digging around with Kory on it, and we obviously spotted a squirrel somewhere...
I use an Arduino Due with the appropriate firmware and CAN transceivers and SavvyCAN. There are also links to buy other appropriate hardware on SavvyCAN's web page.Is it hard to log messages? What hardware is needed?
FWIW, That makes you a Filthy Sand Digger...Back from my week of digging for $ in the sand. Got a tan, but no treasure..
