What's that hand-held computer called?

Your proble talking about a pro link but dont think you can change the gov speed on something that new. Witch eng.

 

You want the road speed not the gov changed if I'm correct . you can buy them on e bay but you will find out that Ryder password protects there ecm.

 

I work at a cat shop and have ryders truck come in with the same thing. I think it stupid. they have them set at 65 and the speed limit here is 70. next time you at ryder try to persuid the password out of them. then buy the prolink

 

We leased our trucks from Penske, and they used computers at the shop to do everything, including setting the maximum road speed. On the Freightliners they were 68, but turned them down to 65 trying to increase the mpg. Since that didn't increase mpg, the drivers insisted on turning the speed back up to 68.

Late last year we got International Pro-stars, set at 70, and they got better mpg than the Freightliners. Not to mention, none of the shifters came out of the Internationals, like they did on some of the Freightliners.

 

If you changed it much, it wouldnt be hard for the company to figure it out when your fuel mileage was substantially worse than everyone elses. The truck's ECM also tracks average speed and highest speed... if they ever pulled that data for any reason, you'd probably be looking for a job.

 

I am pretty sure Cummins is exclusive with there own PC based software now. It's called Insite. Pretty expensive. They also have a handheld device that is more like a PDA, but I think that is only for fault codes. Last I heard Prolink went bankrupt long ago because every time there was software update you had to spend $500 on a new cartridge. So I doubt there would be an old cartridge capable of interfacing with a 2005 because it will have a 2004 emission compliant engine. Like the last post, they will eventually find out what you are up to. It is a nice thought, but you should save your money!
