What software and Devices Hardware do you recommend to reflash ECMs from Semi trucks in united States, like cummins engine, detroit diesel, caterpillar, volvo engines , paccar

I use CAT ET for CAT and Cummins Insite for cummins

Thanks for the Answer , Can you really reflash with insite or cat , I mean like tunning and deleting emmisions

You change horsepower ratings with both but no tuning options like we get for say a dodge, Chevy or Ford. These are the softwares that we use at the dealership that I work for. It’s worth noting that you need a dealer license to change these parameters and good luck with that.

Many of the Cummins HD ECM's are supported by EFIlive for edit and flash. They do not supply templates that enable defeat editing on those platforms fwiw.


Hd cummins engines use calterm software. This is what cummins engineers use to manipulate the software. Cat engines use cat ET. Paccar engines use magic tuner, dimsport or kess tool with ksuite.
