Road speed program
I have to limit the speed on my company's fleet trucks. I have wiTECH 2.0 for the 2018 Dodge ram 2500 and GDS2 for the 2018 Chevrolet Silverado.
Anyone have any idea on how to do it with the factory scan tools. Or will I need something else to do so.
You could phone techline on the 2018 Silverado to see if they offer the program you desire. Otherwise you would be limited to aftermarket programs I as far as I know.
Andrew, HP Tuners may be something to look at. You have to buy a license per VIN but just one time. The device is fairly inexpensive and comes with a few license tokens. I don't recall an option in the GM TIS software or GDS for lowering top speed. With Ford, you can do it with "My Key". I have not seen it in Witech either. You could go through all the tabs in the PCM and BCM / TIPM options
