U7130 Tire Size Adjust?

[lmeyer9916]

Is there a download available that will allow me to correct my speedometer for larger diameter tires with the U7130?

[mikel]

No, not currently.

Is there any intent to create that mod for the U7130?

[mikel]

Tough to say, as that is controlled through the ABS module in the 03-05 trucks, and we dont currently talk to that module.

I ran a google project searching for 2004 Dodge Ram speed calibration and came across these although the are made by a DS competitor.

Yeah, notice it does not tune, so it is a separate tool that just talks to the ABS module. Should do the trick

interesting but kinda pricey for what it does, or does not do

But look at a smarty. It can do it.. I'd love it for the predator to do it.

[RRAM]

look at the price of the smarty. These 7130 came out a long time ago. They do not have enough memory or something inside big enough to take the extra programming it would take to make it happen. One of the mods explained it one time.

On that note can the new trinity do those changes on the 03 to 05 trucks. I know the tunes themselves are the same. But it obviously has much more capabilities.

It is a possibility in Trinity as it has the ability to talk to multi ECUs in one vehicle....
