Before performing slope any operation, back up the current ECU data in case of recovery.

Modifying the original tune may affect the performance and durability of the engine. Please proceed with caution Slither io and consult a...

In some cases, the ECM memory needs to be completely erased before loading the new flash file. This can avoid conflicts between the old file Suika...

Okay. Thanks Jim. So the best option would be to look for a Tune File for Efilive 2021 with my Aisin transmission and Manual Transfer Case? Is there...

You can use Calterm to read it, don’t think it’ll give you a readout the alter and flash back in though and if you don’t have the config files...

Perfect, I'll do that, I called him now and he said yes, he uses the Witech and he may be able to put the 2021 calibration on it. After that, and I...

And yes the 2021 calibrations is when they went back to the CP3

You can change them like that, will not stick though. ECM powers down those changes are lost.

Normally in Cummins Heavy Trucks I can change parameters that I need with Calterm directly connected to the truck or some with Insite and you know...

I think he uses Witech. I'm going to tell you about the 2021 calibration with my Transmission. Because in 2021 the pump is already updated, right?

Just tell him to program it with a 2021 pickup aisin calibration. Don’t know what he’s using to do it but he should be able to program whatever...

Remember that the ECM is blank right now, I think they will program it in the next few days because they made a lot of progress today, they are...

Why not just eliminate the need from the start by using a 2021 calibration? Pretty certain one is on the forums here. If sticking with a...

No, no emissions. Don't worry, I was asking you about the parameters I need to check or change after the pump change, and how I can see them and...

User defined parameters for EFILive or hex editing a .bin version of the calibration being used. Specifics of emissions I won’t give out though.

And what software and interface do I need please?

No, none of those can be used to change the necessary parameters in the engine calibration for emissions or the injector pump.

Thank you very much Jim for the details and for those tips at the end. Maybe it seems like a bit of a stupid question because I've only really worked...

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...
