I’m interested in this too. Software for manufacturer specific vehicles like Ford Power strike or Toyota/Lexus as well as industrial off highway engines and equipment. Kubota, Doosan, Yanmar, John Deere etc.

Many use similar communication protocols but the software for special functions are manufacture specific.

Would love to cut out the dealers and be able to do forced manual Regen and injector tests etc

This seems like the best option. That or stop and go traffic is causing the coolant to over flow and leak out. Possible cooling fan issues if the problem is only in stop and go traffic whereas on the highway at constant speed it’s fine.
