    Not gonna be cheap. Easily a couple thousand bucks. For a 1 time thing I'd just take it to someone.

    You'll need a laptop with Cat ET software and a Cat Comm Adapter for sure. Probably need password generating software as well.

    I have the source for newest software 2021A v1.0 Full service Dealer ET. Also comes with password generator and instructions if you choose to make changes. I had problems downloading the software to my computer when link was sent to my email. Contactacted support at 9 at night and got immediate response and web site owner did it all for me via teamviewer app. Was up and running in about 20 minutes. 200 dollars for 4 year subscription and im in no way affiliated with the source but its legit and was referred to them by the vendor that sold me cats newest cat comm. I agree dont buy the chinese knock offs. Tried one and it wouldnt communicate. You wil ALSO need CATS 6 to 9 pin adapter that costs 100 bucks. Aftermarket or cheap ones will NOT work. Cat changes the orientation of the wires. Pm me if you need link to cat et

    Can I use this to change speed limiter and cruise control settings or would I need the Freightliner specific computer?
