Did another simple install today.
Due to the fact that I am running 35s with 4.88's my speedometer has been off by almost 10%. I decided to fix that by installing a Speedo Healer.
The SpeedoHealer v4 (SH) is the best speedometer and odometer calibrator on the market. Available with bike specific and universal harness kits.

It was super easy to calibrate and install. I just measured the speed via GPS and noted the indicated speed on the speedometer. My Speedometer was at 80MPH when I was actually going 72.5mph. Plugging that into their online generator resulted in this
When you click Generate it gives you some simple instructions.
Once I had this, it was a matter of installing it. It comes with a harness that has the stock Jeep connectors so it is plug and play. In the past, I had a dakota digital and I connected it first to the T-Case, then connected the AiROCK.
This time, I installed the SpeedHealer after the AiRock. My thought was, if the AiRock receives a signal for Active Mode that is a little fast, I am ok with that. The signal will be unchanged when received by the SpeedoHealer which will then modify it and send that signal to the Jeep.
I mounted the control module here, [The module comes with Velcro] to keep it and the wiring away from the exhaust. It loops around towards the middle of the engine bay, then down to the driver side frame rail and back to the T-Case.
After a test drive, everything is working as expected. It's dead on from 5mph all the way up to 75mph. I'll keep an eye on this to make sure it stays that way, but I've seen lots of good reviews on this brand compared to some of the others.
