for those of you with speedoDRD!

anyone on here have the speedoDRD installed on the Jeep WJ? I have 32 inch tires and I want to correct my speedo.

does this thing work and does it actually change the way the Jeep shifts?

I was looking into buying the jet product that corrects the speedo but if this one works, I'll rather go with this one. less expensive

Works beautifully, worth every penny.

It doesn't adjust shift points directly. But it will fool the computer into thinking the jeep is on stock tires again. In turn the computer will shift as it was designed.

I agree. After putting the 33s on mine, the shift points were way off. I installed the SpeedoDRD and it brought the shift points back to where they were before. I found my speed to be off by about 9.8% compared to the GPS.

does it matter which version I get? I see they have version v3m now and it was v3x before.

It should work right?

also when I am done entering the percentage I am off by is that all I have to do? I don't have to mess with any of the other features right?

Yeah, once you enter the correction percentage your done. You can mess with the other features, but I never have. Its geared more towared the bikes anyway.

So I'm just running 245/70/17, so about 30.5", so is it worth it to get it corrected? I think the 1.5" over stock 29" puts speed about 5.5% off.
