They are a wacky ordeal, GM's bastard child brewed in the depths of he|| solely because GM didnt have a PCM that could run the VVT on the exhaust cam of the I6. You can tell they werent liked because the GMT355 platform with the I4/5 motors got the P12 from the beginning and the I6 got it in 06-07.what's the deal with the pcm's? do they interact with the bcm? if not, i don't see why you couldn't swap a 6.0 pcm/harness out of a 2500 onto a SS drivetrain and reprogram the 2500 pcm's tables...
If you have a SS drivetrain might as well use the SS wiring. If not you'll run into issues with the reluctor rings being wrong (another reason the P10 cant run anything else, it uses a 7x reluctor whereas the E40 V8s use a 24x and the E67s use a 58x). This can be overcome easily with swapping parts, but that gets expensive (but again you're doing a swap so what isnt expensive).
If you start with a donor I6 truck, Ive been thinking you might be able to swap an LS1 512kb or 1mb PCM in like the 02-04 LWB trucks with the 5.3 used. If you used a 512kb one you would also be able to run Custom Operating Systems from EFILive or HPTuners for nitrous, SD, etc. Downfall, if you want to use a Gen IV motor you have to swap some hard parts (like the crank reluctor, knock sensors, probably more) and maybe change the fuel system (depends on the donor year TB). But if this LS1 PCM swap works, swapping a Gen III small block Chevy in would be easy. Bolt it up, pick the OS you want to use (build your wiring harness around this specific OS, probably an F-body one), full flash the PCM with the appropriate cal and done. Not an SS swap, but a V8 swap and there isnt anything that says you cant use a stroker LS1, blown LQ9 (ala Silverado SS, Escalade), heck even start with the baby 4.8L and bore/stroke it for some serious power.
And yes they interact with the BCM, they affect the cluster too (but that may be through interaction with the BCM).
The difference between say a 2500 HD 6.0L and the TBSS 6.0L is not simply software. Packaging, cooling system (ours blows compared to the full size), transmission, rear end size/ratio, and then the critical things like iron vs aluminum block, truck intake vs car intake (both have the truck but you can swap them with efans), compression ratio, etc all factor into the power ratings.Yea, I thought they were different Erik. Wasn't sure what the difference was, but figured there were difference, being that the HP and TQ numbers differ so much with the different vehicles. Like I said, not sure about the computers, and how they'll interact with the different components. Thanks for the info Erik! :thumbsup:
