Speed governor password protected!!!!

My truck used to belong to ryder and when I got it, it maxed out at 74mph. But it was also password protected. Cummins flashed it.

 

Cummins will take care of it they can over ride anything with their computer...just ask any volvo owner with a lvl 4 on their emissions filter....after the tow haha

 

Easy fix, the dealer or anyone with the correct software can contact Cummins and purchase a ZAP IT password. It may cost you $100-200 plus what ever the tech or dealer charges. This will eliminate the MPH restriction and allow you to change it to your liking.

 

I have a 2015 flt CORONADO ISX - an i am told the speed gov can not be released - a dealer already tried - I OWN THE TRUCK an would VERY INTERESTED if anyone can do it

 

they sell a box that hooks to speed sensor and tricks it into going faster, speedo be off though,,, xxxxxxxxxxxxxxxxxxxx i think

 

really old M11 is easy to crack. look for any professinal ECM tuner. It is 20 minutes work)
