Tune repository has a 2004 tahoe blue/green with flex fuel... You should be able to use this file and copy over your escalade engine parameters. This will atleast give you a good base Flex Fuel OS...
The only way to use the 2010 TCM is with a compatible E38. GM released several variations of the E38 and T43 so you should keep the ECM and TCM within the same year. Best bet would be to source a...
The 8CKA is a 2008 6L80e. The 0CKA is 2010. The 2010 file is not compatible with the 2008 TCM. If you tried to flash the 2008 file to the used 2010 TCM, you most likely corrupted the TCM. The TCM...
I have a 2017 silverado engine and 6l80e trans (from a 2014-16 truck) in a swap and the VSS displays 158mph. I reprogrammed the TCM with my MDI2 and SPS to the VIN from the ECM and checked the VSS...
Would anyone happen to have a stock read file from a 2021 Silverado 5.3L? Looking to compare it to a file I pulled from a 2018 Silverado E92 ECM I have in the shop.
Long story short, we are...
Yes, there is a difference between an auto and manual OS. The auto OS uses different pins in the ECM for the VSS if I remember correctly. You will need an MDI2 device and use GM SPS to reprogram...
Post your tune file...
Awesome! Thanks for the info. I was just coming on here to post that I was able to reprogram the TCM with SPS to the 2013 silverado with that same OS successfully. Engine and trans ran good on my...
I've come up with the same results. I'll see if I can reprogram it with SPS. The guy that brought this to me broke his original TCM removing the connector and breaking several pins in the TCM. He...
Its the number thats etched on the TCM. I attached a photo of it. Never seen this number before and nothing is coming up on ACDelco or any GM parts sites i usually use to double check before I try...
Hoping someone here can enlighten me on this TCM. Part number on the T43 is 24294925 and the OS is 24294926. Any clue on what year vehicle this is from?
Read the PCM and save the read file. Open the read file and click write vehicle and it should pop up with the license options.
The 2002 wiring harness will be pinned for a red/blue P01 style PCM. 2005 would've used a green/blue P59. Which PCM do you have currently and what color are the retainers on the PCM connectors of...
Cool deal guys. Thanks for the help. I heard back from HTP and they confirmed that programming the T87a after it is unlocked will not relock it. That was my main concern since this is the first 10...
So will reprogramming the TCM with SPS lock the TCM that is currently unlocked from HPT? I have a MDI so reprogramming isn't a problem. Just not sure if it will reencrypt the TCM
I posted this question in a different section but I am hoping to get an answer or advice quicker here.

I have a truck that we swapped an LT4 with 10 speed into and did not have the original ECM and TCM. I purchased a new E92a and had the LT4s VIN programmed into it with GM software and purchased the...
Thats correct for 6l80e/90e transmissions. I dont know how many times i've seen this same issue. Double check the trans plug and make sure it is fully seated and locked in place. there should be a...
After you hook up to the vehicle and start VCM Editor click Flash > Read Vehicle. Then click "Gather Info" which will display the modules which can be read out. This is also where you can select...
I havent found any one list online. Just bits of info from all around and talking with different tuners we work with. Seems that every couple of years GM likes to change just enough in the...

Your TCM OS is to new. You'll need to use TCM OS 24270599 from a 2014-16 6l80e so the TCM can communicate with your 2014 ECM. In 2017 GM switched to an E92A and used a new TCM OS for 2017+ T43...
Any advice? I currently have unlimited gen 4 silverado and camaro unlocked but when I change the VIN from the silverado to camaro and try to Write the new VIN, I get an unlicensed vehicle error with...
Can anyone explain the Change VIN wizard process for an 12633238 E38? I read a previous thread with someone changing the vin on a p01 411 and someone from hptuners mentions that different ECMs may...
