I live in a strict speed enforcement area and need an accurate speedo. Going slower than the speed limit does piss some off some so I decided to try SpeedoDRD. I found the install and setup of SpeedoDRD very simple.
To install I put the tank in service position, followed the pickup wire from the chain cover. The black 3 wire connector was about mid-tank. Was able to disconnect and plug in the Y connector without too much trouble.
I decided to store the device under the seat. I swing SpeedoDRD out by my left knee when making an adjustment. I can leave SpeedoDRD out to check max speed if on a long trip or something.
Mine is currently set to -11.3 compensation. When I did the initial calculations I came up with a speedo -13.3, and the odo was -8.3 off. I'm not as concerned with the odometer. I haven't checked the current odometer adjustment with my GPS against the new comp settings. Will post later when I get numbers.
For a quick guide
Green release = current adjustment
Red release = max speed
Orange release = setup mode
Once in setup mode you serially go through 3 setup option groups,
1st is the option to change locality from MPH to KPH, or no change,
2nd is to decide a positive (Green) or Negative (Red) compensation.
3rd input compensation
If you lose your place turn your key off and restart..
After you turn on the ignition switch and after the device completes it's bat
Press the button and release when the light turns orange
Green release = MPH -> KPH
Red release = KPH -> MPH
Orange release = No change
Green release = positive compensation (Speedometer reads less than actual speed)
Red release = negative compensation (Speedometer reads more than actual speed)
Press and hold button for 10's position, count lights for value (ten flashes = 0)
Press and hold button for 1's position, count lights for value (ten flashes = 0)
Press and hold button for 10ths position, count lights for value (ten flashes = 0)
once you finish the 10ths position the device will flash back the values inputted.
It's really easy. A couple of pics of placement below.
