Turning up speed on engine

Speed adjustments are easily done by authorized truck dealers......or are you trying to get around company policy?

 

If you own the truck, you should have two passwords for the computer. Give your mechanic the passwords and he/she will set it to what ever speed you want. It only takes minutes and wont cost much.

If you do not own the truck I would not turn it up, since the company will know how fast you are driving.

 

If you had the diagnostics software, proper connector and computer to run the system, you could tinker with your own engine.

 

You should be able to buy the software and connectors at an authorized shop, or order them online from the manufacturer. I know Cummins sells the necessary hardware (USB connectors, etc) directly from their website to hook up a PC or laptop to the engine. They also offer the software necessary to make changes, which you have to purchase a license authorization to use (the software itself is a free download).

 

Increasing speed-it's just more fuel to injectors on top gear.Simply you give ECM permit to send more fuel,so you decrease fuel economy(ouch!!!).Also you can void engine warranty(if you have it)

 

I know for a Cat engine, the dealer will sell you both the software ( Customer version of Electronic Technician) " ET" for around $700 plus the cables and a Communication Adapter ( CommII) which runs around $1200.
So, for $1900-$2000, you ,as an owner, can change your own engine parameters such as vehicle speed etc.
Horsepower changes however require factory passwords and are only available to authorized dealers.
My question to you would be, If most authorized dealers would charge an average of 1 hour of labor at an average labor rate of $100/hr, why would you want to own your own program if you own only 1-5 trucks ?
