Thank you for the reply. I was able to load the file to the device by using EFILive V8 explorer. Adding the file gave me a total of four files....

That makes sense on getting a new ecm. Yes there is an updated 2020 calibration that contains all changes necessary for the CP3 pump from...

Disable or ignore signals from the transmission controller so that the ECM does not require input from the transmission.Tiny Fishing

I will get my autocal v3 and ECM tomorrow. I believe I have the correct file for my truck. If not I will have to get a deleted tune for it

That is a Autocal and it is linked to a Flashscan V2 interface box. Whoever he bought the Autocal from will be able to load files for you.

Changing the VIN does not make it compatible with a new vehicle. Have you reprogrammed the new ecm with the correct file?

Thanks for replying Jim. I bought this truck at an auction a few years ago and had it sitting around until I decided to revive it since it was a big...

Dunno why you bought a new ecm for your 2020, unless it was completely toast and bricked beyond recovery but if you’ve read through previous threads...

I guess I should have clicked around some more, the allusion to the V7.5 folder must have been meant more as a memory jogger then. Now my problem is...

Yeah, just copy the CAX files from the old laptop, and save them somewhere on your new one. The converter in V8 allows you to select what folder you...

I think you should adjust some specific parameters in your ECU tuning software. Raft Wars

thanks highlander, that worked, i put the cax files in the user conf. folder. now i see the calibration. would that be in percent of 5v? ...

Latest tune and log. Idle is rock solid now, but still getting a trailer hitching feeling at low rpm (1200-1800). Could really use some tips on where...

The way I got 4lo to work properly was to start with a 12212156 based tune so I could steal the system segment out of a GMT800 truck. That was all it...

Swapping the L83 to L8T on a 2015 Sierra would be possible, especially if the ECM and wiring harness are kept, as the L8T and L83 have many...

It appear the balance test option was removed around 2011. Other threads suggest it was not working properly.

i guess the v2 cannot do this (like e.g. a motec). you can get an unexpensive pulse generator ($5 ?) and a fet driver to pulse injectors.

What's your TCM's part number? TIS asks for that to determine the correct file.

If you have Efilive, plug in your Flashscan or Autocal inline with your laptop, and connect it to your truck. Open Efilive Scan and Tune, and select...

I am facing the same problem. Does anyone have the stock TCM tune for a 2006, 1GCJK332X6F103753? It would be much appreciated.
