I’ve been wanting to get my 17 6.2L tuned for a while now but the only thing that’s kept me from it is the fact the tcm has to be sent off to be unlocked. So I’m thinking about purchasing a tcm to send off so that I won’t be out of a truck while they’re waiting to get it back. Can anyone point me in the direction of a tcm for my truck? I found a couple on eBay but I’m not 100% sure they're the right ones. It also says without CALN in the description. What does that mean? Part number for one or anything like that would be awesome.

Before you do all that look for the other thread on the subject. There seems to be a couple few that can tune without physically hacking your box/s using remote loggers. I'm having some patience as I'm in the same boat wanting a tune but am not going to rush into it too quickly.

Has Diablo given up on the ability to tune the 2017 +  8spd tcm or are they still exploring the possibility? curious as to how much benefit there is to tunning the engine with out tunning the transmission on a 6.2l

You cant just buy a new TCM and get this to work. The TCM is married to the VIN in the truck. The new TCM will be shipped without the OS loaded onto it, the dealer has to flash the OS onto the TCM and also marry the TCM to the VIN.

No way to swap the TCM back and forth without going to the dealer each time.

      OCI, not when but why?

      By Chuck FB · Posted

      I am guessing that engines of that design back then had a better ability to be abused and survive longer than a new design engine with the long timing chain and the overhead cams and phasers etc. But I would never guess that an engine could go that far and not fail spectacularly or at least die a slow death.

      In the 80's 90's I'd run Honda's 7,500 miles between changes using Red Line HP 5W20 and do it for hundreds of thousands of miles with issues. Back in the day it was an SAE 20 with the HTHS of a SAE 30 and SN add load. It was also very polar. Oxidation VOA was over 120. Besides those motors were SPFI and lean burn tech. I could have likely run it longer but never did.    We had a Toyota bought new I ran on Pennzoil's latest and greatest synthetic of the day with "Penthane". A made up word for a very low dose of PAO. Tried 7,500 mile OCI's in that Group III/VI chemistry and the rings tapped out at 90K. Rocker box wasn't as bad as the one Punch put up but it wasn't good either. Also a SPFI motor.    I'm around 3,750 across the board on these GDI monsters and the oil it tapped out by then usually on TBN/TAN crossover and color. Red Line HP Euro.    The AMSOIL SS brochures tell you to follow the OEM values for the service class but that it can be run up to 25K if monitored. I can't imagine what motor could go that distance and not tap out. I've never owned one.    Yes, I know. Lot's of people do. I'm just not going to be one of them.

      I knew a guy in the early 80's that bought a new Monte Carlo and ran it a 100,000 miles without ever changing the filter or the oil. Just kept adding. It looked like that inside.

      My First Project and GMC has me stumped

      By whenindoubtuseahammer · Posted

      Good evening. I was lucky enough to get passed down to me a 2007 GMC LBZ that was my great uncle's. While the underside and rockers are more or less gone I feel like with time I can restore it to working order since it only has 110,000 miles and he put nearly every option he could get without getting the new body style since he did not trust DEF. So far I have done everything I can think of but when I put the key into the ignition nothing happens. I put 2 brand new batteries in it. Cleaned the terminals. Check all the fuses and relays and they all pass with my multimeter. I know I'm missing something that I just cant think of. The only odd thing is the OBD2 port works which makes me think its not the mega fuse. Any advice would be greatly appreciated.

      Looks nice. I still have my 2000, 1500. Bought a 2025, 1500 for retirement. Feels solid. These trucks have a bad rap on the internet. My brother has a `24 1500, 5.3 with 52,000 miles. No problems at all. Mine hasn`t either but mine`s only at 12,700 miles. Have seen some of these things with 100,000 miles with no problems.
