Speed governor password protected!!!!

If all fails, maybe unplug the speed sensor from the transmission, use a gps to see your speed.

It might work????

 

what company was the truck from...they all have patterns involving a word (numericly and part of the vin)

 

cummins has software that will zap the password and reflash the computer. cost $140 but puts everything to o/o specs.

that means wide open on all parameters.

no need for PDI.

i did it on a truck i was once buying from a company i was working for. the truck was originally swift. with isx motor

 

That's pretty said Rocky Mountain can't get you through a quick lane. How long does it takes to hook up to a computer? Jeesh. I'd ask to speak to someone else and complain.

 

i was in dallas delivering a load. i hit up the cummins first thing when they opened before delivering my load. no appt. got me in and out in 30 minutes. i didn't have no governors set. i did a straight zap and reflash. ended up with more horses and .75 better fuel mileage. best money i spent for power and mileage.

 

The word you're looking for is alphanumeric and, no, they aren't, necessarily.

 

Did they try "0000" for the password? Pretty common one for fleets to use for trucks they sell off.
