Speedometer/Odometer Reading Double

[blob]

My 2013 PC 8 I bought this year as a holdover has read double on both speedometer and odometer since new. Just had dealer replace speed sensor and do gear update and nothing changed. Anyone have any similar issues or ideas where the problem might be? It is set for MPH not KPH. TIA

i have a 2014 m8000 and i had issues with my spedo on sunday. it would only do it while wide open. needle would peg out and all of the digital part was light up. did it for a few miles and then stopped. took it to the dealer and they found nothing. not sure if theses problems could be related?

My 14 is doing the same thing under normal riding; Hard to fine issue with no codes. I assume bad gauge,ccu or wire harness grounding; If someone figures this out chime in.

Izznis's gauge re-flash may fix it? Maybe pm him, he might know something about it with all the work he's done on them.

Gauge is resetting while you are riding. When restarted it cycles the needle and lights up the LCD completely.

I used to have this problem with my original gauge. My thoughts are that since at least 3 people have had the problem it likely is a software bug. A lot of people probably miss it too.

My original gauge ended up being left on a trailer and flying off while going 65mph on 694, so I wasn't able to tell if it would randomly reset after my reflash, but I've never observed a reflashed gauge reset itself like that either.

I can tell you though that if I had a bug during development of the reflash, the classic reaction is to reset the MCU because of an illegal op code, which is the equivlent of a blue screen on a PC.

If it is a software bug with the stock software causing it to reset it wouldn't be the only bug. For sure on the 09 gauges, but maybe on even late build ones, if you turn the sled off while setting the clock or altimeter it puts the gauge in a state where the clock or altimeter keeps flashing, and the set button doesn't work.

I can fix those gauges by reflashing them btw.

Thanks

Thanks - What is your current turn around time for the relfash with afr option?

I ship them back the next day after I receive the gauge. The AFR kits will be available by mid next week I believe, but the reflash that supports the kit is available now.

Changed gauges does the same thing. I still think it's the ccu. If someone finds out let us know.

The CCU and ECU never see the speedo signal as far as I know. It is either the sensor, the magnets, the wire, or the gauge. It's a weakish signal in the first place, so interefence could be playing into it.

I guess that makes somewhat sense. But would this cause the gauge to reset? That's the best way to describe it. Needle goes up dummy lights go on. Then go off.

Ah, you are talking about the random reset.

If two gauges do the same thing it tells me there is likely a bug in the stock software. Likely all gauges do this, but people often don't notice. The other option is perhaps the power to the gauge is flaky enough that it resets it, but that seems unlikely...

The gauge is off my wife sled and her sled doesn't do this. I guarantee anyone would see my issue because it's so annoying. I guess I'll start chasing the power wire.

 

[Buz]

It also flashed ccu once but no code. So I'm still wonder about trying a replacement or could the gauge power wire do this? ?

Just got my sled back from the dealer and the problem of odometer showing double miles and speedometer showing double speed is fixed. Replaced speed sensor and no help. Then changed the plug on the end of the driveshaft that contains the magnets that the speed sensor reads and that fixed the problem. Thanks to Sno Pro Man on HCS for pointing me in the right direction for the fix.

Does anyone know which way the magnets are suppose to be? I had them out accidentally when I did my belt drive. Put them back in with the tops repelling each other and now I have no speedo.

I had a conversation...

Talked to Kevin @ C3 yesterday - the magnets have to be opposite each other, meaning one + and one - facing out. Having both one way will result in no speedo, or the speedo will read double as the pickup senses both. Hope this helps you.

You ever find a fix for this mine is doing the same thing? Thank I’m advance!

You ever find the fix for this mine is currently doing this

Send it to Next Stage Guages for the reflash. Makes the guage much better ins so many ways and will probably fix your problem if it is in the guage.
