Supporting Member knyte Posted July 13, 2020 Supporting Member Share Posted July 13, 2020 In searching around, it seems that the speedo should be pretty accurate. I find my 2015 FJ to read quite a bit faster than what my GPS reads. I haven't worked out the % of error. I have changed chain and sprockets, but haven't deviated from factory. It's still out of whack Can this be calibrated? I'd prefer to avoid the SpeedoHealer (I use that name generically) route (had to install one on my DL1000. It's not the work involved so much as the expense. I'd install one if needed; just not sure it is). 2015 FJ-09 / FJR touring bags / oil plug mod / Evotech rad guard / SW Motech bash plate / VStream touring windshield / Seat Concepts: Sport Touring / Vcyclenut ABS rings (speedo correction) / Cosmo RAM mount Link to comment Share on other sites More sharing options...
SKYFLIX Posted July 13, 2020 Share Posted July 13, 2020 Most, if not all, ECU reflash companies offer speedo calibration. Not sure if it can be done any other way. Link to comment Share on other sites More sharing options...
Michiel900GT Posted July 13, 2020 Share Posted July 13, 2020 (edited) Hm, Yamaha must have changed something when comparing the FJ and the 900GT then. My speedometer doesn't seem to be very accurate when compared to the GPS. The higher the speed the bigger the difference. It is up to 10 kilometers slower than my GPS shows. Well, it keeps me safe from too many speeding tickets I guess... Edited July 13, 2020 by Michiel900GT Typo 1 Link to comment Share on other sites More sharing options...
Supporting Member knyte Posted July 13, 2020 Author Supporting Member Share Posted July 13, 2020 (edited) That's roughly what I'm seeing, too, but it reads fast compared to GPS readings. The math will work out to an error in %.

littlebruv Posted July 13, 2020 Share Posted July 13, 2020 Speedo error reads about 55mph = 50mph and 100mph = 90mph in real world speed on the 2017 Tracer 900, this is when i compare to my Tomtom satnav Link to comment Share on other sites More sharing options...
Wintersdark Posted July 13, 2020 Share Posted July 13, 2020 Yup, reads 8-10% high. In fact, every single bike I've ever owned, and every single car reads about that high too. AFAIK the tracer uses the ABS sensor for speed, so changing gearing shouldn't impact the speedo. Link to comment Share on other sites More sharing options...
Basket Posted July 25, 2021 Share Posted July 25, 2021 Recently checked my 2020 gt against my phone Gps. Bike indicated 110 Kph and Gps said 102Kph. So the speedometer is about 8% optimistic. However the odometer is only 2 or 3 percent off. So if I correct the speedometer with a Speedo Healer, then my odometer will be way off, is that correct?

MightBeSasquatch Posted July 27, 2021 Share Posted July 27, 2021 Same issue with the 2021, I have noticed about a 10% fudge factor in the speedometer after passing high score signs. I keep meaning to set up an app to see what the GPS is reading out comparatively but haven't yet. If I do I will try to remember to report the results. 1 Link to comment Share on other sites More sharing options...
Supporting Member knyte Posted July 27, 2021 Author Supporting Member Share Posted July 27, 2021 At the next tire swap (possibly sooner...) I plan on installing these for a somewhat low-tech fix. It's a minor gripe, but I miss the large display / readout. Currently I've been using my Garmin as a speedo, but the screen is considerably smaller and finding the right group of numbers can take just a few ms longer than desired. 2015 FJ-09 / FJR touring bags / oil plug mod / Evotech rad guard / SW Motech bash plate / VStream touring windshield / Seat Concepts: Sport Touring / Vcyclenut ABS rings (speedo correction) / Cosmo RAM mount Link to comment Share on other sites More sharing options...

I don't see it in your tag line @knyte but do you have a McCruise? I only ask as there is an add on for the McCruise that does just what you want for a reasonable price. 1 Link to comment Share on other sites More sharing options...

No, I don't have one - yet. Still haven't settled on a CC solution yet, but McCruise is certainly in the back of my mind. Price-wise they seem very close. It looks like the McCruise is a bit cheaper.

bwringer Posted July 28, 2021 Share Posted July 28, 2021 Weird... my 2015 only reads slightly below actual speed shown on GPS. Maybe 1 or 2mph at highway speed. I know it's had an ECU reflash; were they fairly accurate from the factory, or was mine corrected from the re-flash? Just about every other bike I've owned reads the standard 7% or 8% under.

I've already ordered the correcting rings... I've just ordered one for myself as I was looking a little while back for a speedo correcting option and was looking at both the rings and a Healtech option at the time. I thought I'd ponder on it for a little while longer and just recently came across the McCruise option that I wasn't even aware of. As I have a McCruise it made my choice so much easier. The good thing about this type of option (Healtech included) is that it can be recalibrated if required with tyre and sprocket changes. 1 Link to comment Share on other sites More sharing options...
Supporting Member knyte Posted August 7, 2021 Author Supporting Member Share Posted August 7, 2021 New ABS rings from Vcyclenut arrived Thursday. I hope to install them this weekend. 2015 FJ-09 / FJR touring bags / oil plug mod / Evotech rad guard / SW Motech bash plate / VStream touring windshield / Seat Concepts: Sport Touring / Vcyclenut ABS rings (speedo correction) / Cosmo RAM mount Link to comment Share on other sites More sharing options...
