Tire Size Calibration still not working U7137 w/ 9r09

[WKgrand08]

I updated my Predator to the most recent 9r09 crom. My 2008 Grand Cherokee 5.7L still will not accept tire size calibration. I have been waiting on a fix for this for quite some time. Just wanted to inform you that it still is a NO GO and is not working. Thanks.

Same here. 2010 Jeep Grand Cherokee, CROM 9R09. When attempting to change tire size, either by sidewall height or tire measurements, hitting "Apply" results in a "failed to update tire size" message. CalID 68060516AC, currently loaded with Diablo-provided winter tune.

Any idea on a timeframe? Speedo is way off with taller new tires....

I have a 2004 ram and I had 33 inch tires,went to 35 inch tires,
had to set the tire size to 31 instead of 35 inch to get the speedo right.
Any size entered above 33 would not make any differance.
Go figure,just a thought.

+1, have been waiting on the "promised fix" for ten months now.....after all that was the main intent when it was purchased.

Bump for a little love and acknowledgement!

Bump.

For some oddball reason the GC's are hard as heck to come by, if you know anyone on any other forums that has an 08-up GC feel free to have them contact us, we would only need the vehicle for less than a day and the owner would get a freebee out of it in the end.

Wish I were closer than Colorado- I'd be happy to share mine! Hopefully someone closer can step up. Thanks for the update.

ALL. I have a MUCH better idea. How about Diablo Sport forks up the money to come visit one of their MANY customers who have a 2008 Jeep Grand Cherokee?" Obviously your company has made much more money off of us then it would cost for a plane ticket, correct? Since it would only be half a day, you could be back home by night. I believe you could get a round trip for less than $400. You would make everyone happy. In fact we would recommend your products more than not. In turn that means more business for your company by us and future customers. I think after 10 months, this should be done.

I work in a Technical Support group for an IT Storage company. We do this when it is needed. I think your company should now do the same.

If not, I am in all honesty ready to drop this product. There are others ( I won’t mention), that our available. I’m sure everyone else on this thread can agree to this. The same goes for everything said in this post.

Comments?

Not that simple to drag an engineer, a tuner, and a boat load of testing and tracing equipment on a plane for a day...there are reasons we have to do development work here in house.

Well, is it possible to rent a 2008 - 2010 JGC? This was brought up in the past and there was no comment.

[mikel]

I've never seen anyone rent the HEMI models.

[klein1j]

Do we have any other options besides waiting on someone to bring you a JGC HEMI?

[airportdave]

Gotta be a Jeep dealer near DS that will let one of your interns take one for a "test drive"....

I agree. I mean 10 months, come on… This is ridiculous. Something has to give. Do whatever it takes as a company. Think outside the box.
