Trail Tech Computer

[Green Hornet]

I have some info regarding the calibration of the Trail Tech Computer. After using the calculating numbers provided in the instructions, the Digital Speed did not seem to coincide with the approximate visual speed. I used the stock odometer to calibrate the computer. Set the Wheel Size to 2205mm and then drive a known distance (I used 1 mile) Multiply these two numbers 2205 * 1.00 then divide by the milage displayed on the Trail Tech (My case was 2.05 miles) 2205*1.00/2.05=1021mm (Approximate) I then used GPS to verify the speed & the stock Odometer to verify the milage & its seems to be close to dead on. I emailed Trailtech about this huge discrepancy and am awaiting an answer. Just some info for you guys to check your computer, because I doubt I'm the first.Trail Tech recommended the W/S @ 2110mm(NOT). It is a nice setup though :cool: :ride:

Thanks for the insight. I've got three to install. I assumed it would be fairly straight forward. That's what I get for assuming.

The install is not that bad, but if you have an odometer unit w/the bike use that to help verify. Also try my settings if you have a 21 inch front w/rotor. If the sensor & magnet were placed along the area of the rims then the instructions would make more sense since the full rotation of the tire would be in play, but since the sensor & magnet are in the rotor area the circumference is smaller. FYI One computer is programed to be used on two different bikes

I just installed a trail tech computer too. The instructions suggest not to position the sensor on dead center with the magnet or else the the computer could double count the revolutions. Is it possible this has happened to you? I have an Michelin S-12 on the front and have mine set at 2121. That seems be accurate for me.

:think:

Mine is set as they recommend. It passes at the tip. If you hav'nt checked the odometer w/your stock try it. Everything worked fine but I know I was not doing 75 in 4th :laugh:

I have also installed as the instructions stated and have a policeman as a neighbor and had him radar the bike afterward within 1 tenth of a mile an hour per the radar gun.

I think you were getting the double count as stated above i have my pickup mounted on an angled piece of steel attached to the lowest caliper bolt and the magnet just passes the tip of the pickup as suggested.

I adjusted the sensor this morning. Now the instruction numbers make sense & work, GPS had me at + - 1mph & the odometer seems to be pretty close now. :think:
