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 already installing the entire interior, and the engine and transmission are installed, there are still a few details missing, fuse box, some harnesses, etc. I will be with the programmer when he does it. Or do you want me to tell you the exact details of the calibration, ecm code etc, when he finishes?
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 calibration he wants to it
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?
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 that with Calterm I can get the calibration of the ECM and make the modifications that I need, but I know that with this it does not work like that, I have never really connected to any, In these how can I get the calibration after it is programmed? Can I change any parameter directly connected to the truck?
You can change them like that, will not stick though. ECM powers down those changes are lost.
And yes the 2021 calibrations is when they went back to the CP3
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 verified that it starts and everything is fine, I want to do the other thing that you know. Thanks a lot for the help and advice Jim. How can I read the calibration of this ECM? I would like to read it and save it in case I want to make any modifications in the future.
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 needed, won’t make a difference anyways as it won’t open the readout. You can read it with hp tuners and use that but at higher risk of bricking the ecm just from reading it alone and tune with hp tuners or there are EFILive tune files on the forum to use to tune.
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 a number or something specific I need to look for the Tune File After they program it for me, stock ?
