HELP GAUGE REMOVAL /CUSTOM TACH

That's my interpretation, but i would read it carefully. The original post was over 4 years ago, and they haven't posted since. You might try contacting them directly.

We don't know if your premature rev-limiter is caused by your particular gauge, or incompatibility of the bike's ECM.

I've been doing some digging on this forum and I'm pretty sure it's because my original speedometer isn't sending a signal to the ECU anymore. From what I understand the signal goes from the speed sensor to the stock meter then to the ECU. The stock meter acts as a translator to the ECU. Without that speed sensor reading the ECU has a sort of failsafe that limits the rpms to 5,000. I could be wrong, but I've been reading about others having a similar issue with the 2014's. That's why I think they just swapped the 2014 ECU to a 2013 on this thread to eliminate that issue without having to reflash the ECU.

If I can't find another work around I plan to do some digging into Arduino boards and programming it to receive the speed sensor signal and translate it into a reading the ECU can understand. Who knows how long that will take me though seeing as I'm not a programmer and I don't have any programmer friends. I'll also have to figure out what signal or language the Honda ECU needs to communicate.

The problem may be the particular model of universal instrument that works on anything from 2-stroke scooters up. These units are designed and made where singles and twins predominate.

I applaud the efforts you have been making. But before any further expense, try re-attaching the stock gauges, and unplugging the rear wheel speed sensor. That could validate your theory.

I can't recall an incident where a faulty speed sensor circuit (mostly bent pulser rings) caused a lowered rev limit.

And how did we get from your original post to this one?

Good points. We got here because I was digging around in another thread of someone who modded their speedometer and ran into similar issues, lol.

The only problem I have with reattaching the original speedometer is that I’ll have to clip the original wire connectors off and install bullet connectors on each wire. Which, I guess doesn’t matter much now since I already clipped the connectors that go to the bike unless I wanted to sell the stock speedometer separately sometime.

Well … Lord Popgun or someone may be able to tell you where to get the opposite of the OEM connectors so you could make bridging cables.

I think I may end up getting a breadboard and some jumper wires. I’ve been meaning to get one anyway.

If we could convince someone to unplug their rear wheel speed sensor on their 2014 standard, we could determine if that is the cause. I'm not sure doing so on an ABS model would be valid.

I talked with Honda and they didn’t have any suggestions. I also talked to a local guy who dyno’s motorcycles for a living and he was stumped.

I ended up just reinstalling the stock speedo. It now has it’s original RPM range and works just like it should.

Thanks everyone for all of the troubleshooting tips! Until I can figure out how to program an Arduino (or something similar) to read the stock speed sensor and send the correct signal to the ECU, I’m keeping it stock. I’ll send an update to this thread if I ever figure it out.

Thanks for the update, wanobiben. I hope you succeed.

I wonder whether it might be worth contacting Doh Guhl—the guy who used to reflash CB1100 ECUs. You never know.

Sent from my iPhone using Tapatalk Thanks for following through with a conclusion, albeit not the one you wanted. I would be very interested to know if unplugging the rear wheel speed sensor is indeed the cause of the premature rev limiter. Maybe we can figure this out.

Just unplugged the speed sensor to test it out and it went well above 5,000 rpm. Now I’m wondering if it has something to do with the gear indicator.
