HealTech Electronics SpeedoHealer

 

Removing the factory connector from the speedo sensor

With the red locking tab pushed into the unlocked position, pull the factory connector straight off of the speedo sensor housing (in the direction of the yellow arrow).  Congrats, you are almost half way finished with the harness installation! 

Connecting new SpeedoHealer harness to speedo sensor

With the factory connector unplugged from the speedo sensor, it is as easy as 1, 2, 3 to plug in the SpeedoHealer harness.  First, plug the SpeedoHealer connector (I've labeled it #1) to the speedo sensor.  After you do, be sure to push the red locking tab up into the locked position, as shown in the above photo. 

Next, take the other SpeedoHealer connector (I've labeled it #2) and plug it into the factory connector (I've labeled it #3) that you previously removed from the speedo sensor.  As before, be sure to push the red locking tab into the locked position, as shown in the above photo.

Nearly done with this end of the cable.  After the two SpeedoHealer connectors were mated with the factory connectors, I started routing the cable forward to the engine compartment.  Since I already had a cable/hose bundle running along the driver's side frame rail (also where the brake hard line runs front to rear), I opted to run the SpeedoHealer cable along the same route. 

As I sometimes have a tendency to do a bit of overkill, I grabbed a few more zip ties from the stash I keep in my electrical tool box and made sure the SpeedoHealer cable was totally secure along its path.  I've never snagged an electrical wire, ARB air line, or radio cable out on the trail.  As such, I installed this cable with the same attention to detail as I've done so many others. 

SpeedoHealer mounted in the engine compartment 

Once I got the SpeedoHealer cable all the way up into the engine compartment, I plugged the SpeedoHelaer's pigtail into the cable and mounted it on top of my sPOD housing.  The SpeedoHealer comes with the generous portion of Velcro attached to the bottom of the unit.  I peeled off the backing, cleaned the spot on top of the sPOD with some alcohol and paper towel, and stuck security in place.  With the supplied Velcro, I can temporarily remove it from the sPOD should the need arise and then attach it later. 

So there you have it....the install is complete.  It took me a lot longer to type this up than it actually took to complete the installation.  Having now done it, I've no doubt that someone's 15 year old daughter could do it in 5 minutes.  (but I'll bet my use of zip ties was better than hers!  LOL!!!)   

From here, it was time to switch over to the docs that came with the SpeedoHealer unit.  These describe how to actually enter the calibration numbers so you can dial in the unit and get a dead on speedometer indication.   While reading the docs, I noticed that I can enter two different calibration setups to accommodate two different tire sizes.  Why?  Some folks put different sized tires on during the winter months (snow tires) and so this allows them to program the SpeedoHealer one time and then switch back and forth between the two configurations.  Nice touch for sure! 

I've had a high quality Garmin GPS for years (actually, I've gone through 3 different Garmin GPS units over the past years).  It was easy enough to slip my Garmin 60CS into the Ram mount and take the TJ for a spin. 

I opted to use the formula in step 4.2 (page 3 of the docs) to calculate the calibration value I would need to plug into the SpeedoHealer.  Per the docs, this is an alternate method to calculate the calibration value.  This worked out well as I didn't have time to run out to the freeway so I could cruise 60 MPH and determine the calibration value from the table on page 4.  It worked well....as I ended up with a nicely calibrated unit using 30 MPH as my reference speed.  After all was said and done, I checked it against what the chart would have provided me had I been doing 60 MPH (hard to do in the local neighborhood) and the calibration numbers (mine and from the chart) matched right up.  Since I don't use snow tires here for central Arizona driving (we don't have snow), I didn't pursue the option of mounting my snow tires and getting a calibration value for them.

That about wraps up this review of the SpeedoHealer from Blue Monkey Motorsport's .  If you find yourself in a situation where you are tired of your speedometer giving you an inaccurate speed, give the SpeedoHealer a try.  It works, just as promised....and given the wide range of values you can enter, I doubt you can gear the TJ and find a set of tires for it that the SpeedoHealer won't make right.  Besides that, you won't have to log onto the Jeep forum any more and tell folks...."I get 270 miles to a tank of gas."  With an accurate speedometer, you'll actually be able to determine just how bad your TJ's mileage actually is!  <grin>
