So you stick on monster tires or gear reductions, super but the MPH indicator is now off a bit. Here are a couple of ways to compensate for that.

First free calculators OnlineConversion.com - Bigger Tires or Calculator - Speedometer Adjustment for Tire Size Change | Interco Tire.

If you want a permanent fix here are two companies that have solutions for our Talons. Pricing is around $100. The connection for the instrument panel MPH indicator is located on the 4 wheel drive clutch. To get to it I removed the front passenger side tire to make it a bit easier. My connector has a green stripe on the black connector.
476
477
478
479


Below is a picture of the 12oclockLabs MPH correction and is for a specific tire diameter. I have this one.
480


Another company making the module is Healtech SpeedoHealer v4 the part numbers for are:
SH-V4-AB and SH-HO5 below is what they look like, the extension will allow you to put the module up and away from the mud/water/sand/rocks.
481
482


Although I have the 12oclockLabs version I worked with Healtech to determine the correct parts for that kit. Either will work just fine. I like the fact you can get an extension with the Healtech kit to get it out of the mud. Also a bit easier if you change to a different tire or gear in the future.

Hope SuperATV will also offer ones for the Talon in the future.

So do you just order it set for a certain tire size or can you change it yourself?

I'd like to have it corrected for the tracks (~14" tire) but also be able to set it for the 32s when I put those on.

With either one you can adjust to a different tire size but with the Healtech SpeedoHealer v4 (part numbers:
SH-V4-AB and SH-HO5) you could extend the module to the cab up and out of the elements and it would be much easier to get to. The one I picked up is under the hood and only has one LED and a single button it is tricky to set up and without soldering more wire difficult to get to. The Healtech version would make it easier when you switch back and forth and has a very wide range of adjustments and sounds like it would meet your needs.

If you get a IGR installed do bypass the speedohealer until I get the chance to test it with the IGR modules. There are two IGR modules and they must be exactly the same and for now mine are set for 24.1 and the Speeodohealer for the MPH conversion is 25.1 and initial testing proved they will not work together. I believe all must be exactly the same and I will test that out once I have a few weeks running the IGS. After installing the IGS I will be purchasing two of the extensions today as that will extend the electronics much higher and away from trash, water, and mud.

Hi Jefferson, that would provide some cold weather testing as well and I'll bet they would be a hoot to play with. Are they expensive to replace tracks?

Ok the individual speedohealer should be installed and programmed on your talon or it may not work at all. Not difficult but has to marry with the ECU. I am currently running two of the speedohealers to adjust transmission shift points. The two are required with an Internal Gear Reduction (IGR). I have another on the way to correct the MPH reading and again it must be installed and then programmed for the proper tire size. If you change tire sizes with an IGR I will have to get additional assistance making sure they do not interfere if set at different ratios. Currently my ratio for the two shift points is 24.1 and I will match that with tire size. Going to a different tire size has never been done but I plan do just that around the end of the year and will test that setup.

so are you now running (3) of the 12 oclock units or something different? If 12 Oclock, do you have a part number for the extension cables?
