Hey guys ...

I got myself a Trailtech Voyager and installed it ... Really took my time to do the wiring neatly and properly ...

So it came to installing the engine sensor (tach) wire. The enclosed instructions said to wrap the wire 5 times around the plug wire. Did so and taped it down with some tape just to make sure it does not come loose. Started the bike... and saw that it was idling at around 11000 RPM. Now surely that cannot be right.... Did some reading and found some people saying you should put the sensor wire onto the input wire directly on the coil. So I proceed to do that .... Same result !

Now I start playing around as I see other guys complaining about bad earth and all sorts of electrical issues ...

Just to be clear .... I wired the GPS unit's power leads directly to the battery.

So... I unplug the power lead from the unit so it runs on internal battery ...and the Tach reading seems to be correct ... The bike now idles at around 1500 RPM. Now I am thinking there must be something wrong with the power lead/circuit.

Here is the kicker .... I connect the black wire ONLY to the battery .... The tach jumps up to 11000 .... disconnect ... back to 1500.... this time the red wire ONLY .... tach jumps up to 11000 .... WHAT THE ???????

Now the question is ... Has anyone seen this behaviour before ? any ideas ? is the battery the correct place to connect the power circuit ?

Can anyone suggest anything ?

The wire should wrap around the coil on your X, not the wire. Going direct to the wire on top of the coil would be for low voltage situations (which you do not have).

You get the same results with touching pos/neg because the Trailtech is polarity neutral (think that is what the call it ) where it can be wired on either side.

option 4 in this PDF shows the coil wrap but it looks like they recommend option 3 - may need to change my setup ...

just installed my vapor yesterday. Tach work perfect. Hooked the red vapor wire to the driver side wire of the coil (sorry forgot wire color) and hooked the black vapor wire to the grounding bolt in the center of the coil.

I assume the Vapor and Voyager use the same system except the voyager has gps too. Go into your mode setting and check the PPM setting, maybe it was default to 2 or .5 or something. Should be set to 1, at least for the vapor.

Another trick you can do is use alligator clips and long wires to try different contact points until you get a combo that works.

I also have my vapor power wired to the battery via a relay that clicks on when the bike is running. Relay is fused and supplies + juice, the ground is hooked to the - of the battery and have had no issues.

I only hard wired my to battery. Works great . Who needs to see rpm on a dirt bike anyway.

Can anyone tell me what the correct idling speed for a 450x is? I get around 1600 rpm... That sounds a little high!

Your good, it's 1700+/- 100 rpm's, adjust it depending on your needs. I.E., if your bike stalls alot, then turn it up...

i finally made it. tachometer works great. but you have to be patient and test it many times.will explaän it later with pics as i m away from home- in estonia. rpm is around 1700.

Had the same problem on my 12 450x, ended up being a software issue on mine. I called Travis at trailtech he had a new head unit in the mail that day. Great service.....

Same problem on my 2009 450X. 5 emails back and forth with Brian at Trail Tech, no help at all. I provided software version, serial number, detailed installation connections, and detailed troubleshooting steps and results. Last response was "I ran it by a few other guys in the shop and we are all puzzled. You are definitely picking up interference from somewhere, but where exactly I don’t know."

venturure, if you could provide information on how you resolved yours that would be fantastic!!

I was told by trailtech that they had updated the chip in the unit, so they sent me a new unit to trade it out.. Your not that far from trailtech as they are in battle ground could alway see if you could bring it to them to get it fixed right

Called Trail Tech on Thursday, new unit arrived today!

excellent customer service from Trail Tech.

Few months old Voyager stopped receiving GPS sat signals?Have u ever had any such issues?
Thank you.

not typical. call Trail Tech and they will work with you on this issue.
