Not without a custom tune.
I was wanting to be able to set my temps, perimeters, boost ect. and also be able to change to tow, street or performance.Why dont you tell us what you are trying to do... why would you want to override anything if its working fine as is?
Dont confuse a programer with a monitor, if you just want the screen then you can certainly buy it and plug it in with no issues.
The tuning itself is illegal and you cannot buy new programers with delete capabilities and you will need a shop to provide you with a custom "off road" tune.
All you need is this, and its simply plug and play.I was wanting to be able to set my temps, perimeters, boost ect
This is where you start complicating things, and you will need one of these:and also be able to change to tow, street or performance.
