Reflashing computer?
 

Hello i was wondering how do you reflash your computer in the vp44 trucks?

Buy a programmer like a smarty or you can take it to the dealer and they will but you will get no benefit out of it.

well i heard sometimes their will be a hypetec orsum porgrammer in your computer and then it can mess up another chip thats on your truck?

Do you mean someone used a OBD II style tuner like a superchips or hypertech and left the tune in the truck? :humm:

well how can you tell if its still in my truck?

Well I do believe if you turn the key on, then off, then on it will show if you have any codes if I remember right. Or you could just get another programmer and overwrite it...

i had the dealer put the ho program on my 99 cummins around $70.00

Yea but some more money you could gain a alot of horsepower... :tu:

doesn't work if you use a hypertech to try and write over a hypertech as they download the stock info so you can go back to stock. I am not sure on the smarty or superchip.

Superchip does the same thing...
