Speedometer Calibration with 3.0 CRD
 
Installed an OME lift in my dad's 2007 with the 3.0 and threw some 265/70R17s on it and it looks and rides great. Now we want to calibrate the speedo but I'm having trouble finding a programmer to do so. I've spent some time searching today and have yet to come up with a solid answer for this.

I own an '08 with 5.7 and tried using my Superchips Flashpaq, but as I suspected, it couldn't make contact with the ECU since it doesn't support the diesel motor.

Is there a programmer out there that will work with the 3.0? I am not too interested in a tune, just want to change the tire size...

After hearing some people were having luck with Hypertechs speedometer calibration programmer I ordered one to give it a shot and it did indeed work with the 3.0 diesel, even though they only claim it works with the gas WKs.

Hypertech part number: #752501

Does the hypertech also support changing axle ratios in the crd?

I never changed the axle ratios with the Hypertech unit, but since it is capable of doing so, I don't see why it wouldn't work since the tire size calibration did.

I use AutoEnginuity software to change the speedometer calibration on my CRD.
