2014+ DL1000A Speedometer Correction Success!
Like so many others, I noticed that my speedometer was reading high. When it said I was going 70mph, I was actually going 64. I know that this topic has been discussed at length so I won't get into it too much other than to say that since the ABS was added in 2014, it's made the process of correcting the darn thing much harder.
As others have noted, you can access the Speed Sensor Output Signal (pink/white wire) at position T37 on the small connector of the ECM. It's really easy to spot because it is right on top of the bundle. BUT, since my bike is brand new and still under warrantee I am loath to do anything (like cut into the ECM cable bundle) that might cause any questions should I have to take it in for covered service. So, the question is where else can I get to it that is relatively easy to get to. Taking off the instrument panel is a definite bugger and accessing switched power is not really nice. Plus, how do you get to your device should you want to change your adjustment?
Well, I think I found the place: The instrument panel connector bundle on the top right side of the radiator (left side if you are facing it from the front.) And although switched power here is a bit of an issue, I have a solution for that too. So:
1) Remove the right hand radiator side cover (the lowest cover with the single bolt holding it on). You might also want to remove the aluminum trim piece at the top of the tank to make it easier to reach down.
2) Locate the Instrument Panel Connector Weather Boot at the top left of the radiator next to the radiator cap. (images 3 and 7) Pull the cap back and unclip the three connectors. They are all keyed and can not be misplugged when you reconnect them.
3) The Speed Signal is the top connector and is the pretty pink and white wire. (image 4) You will have to cut the black tape around the bundle back a bit to give yourself enough room.
4) Cut the pink/white wire half way between the hard bundle cover and the connector. You can use the splicers that come with your kit but I prefer to solder the wires and cover with heat shrink (image 5) but whatever you do, make sure you have a good and permanent electrical connection and that the correct wires are on the correct side.
5) For the switched power and ground I used the Heated Grip connector hidden behind the center of the radiator beside the other connectors there. Using Suzuki part#36852-06g00 I was able to bring the signals out to a place I could access them. Actually, I had installed auxiliary lights previously so it was already there. Just be sure to keep the polarity correct as both wires on the adapter are the same.
6) I located the correction device (SpeedoHealer) on the front of the frame just below the triple camps where I can get to it easily in case I want to adjust it. Hey, I live in California so you all know I never have to worry about rain.
After I plugged everything back in, put the covers back on and readjusted the clock (the only thing that got reset) I entered a correction of -8.2% and WOW, it really worked. It's now spot on, or as close as I can tell with a GPS and a speed sign near the house.
Although I can't be certain, I imagine the SpeedoDRD and the other devices would mount similarly.
