Hey guys! So I recently changed out my speedometer for a digital one. I should have everything hooked up properly as it all reads out okay on the new meter. The weird thing is that since I changed the meter my rev limiter is hitting too soon. It now redlines at about 5,500rpm now no matter what gear it's in. Is there an easy fix to this or am I going to have to take it to a shop to have the ECU reset or something? Thanks in advanced!

If I had to guess I'd say that is what the redline on the new tachometer is programmed to be at. Is there a manual that will show you how to program it to a higher redline on the tach?

Unfortunately it was a really cheap digital meter and it came with minimal settings. I cannot figure out what file type is accepted on this forum to post an image either. The meter comes with instructions on how to change the number of signals, tire circumference, fuel gauge (2 line or 3 line), and number of cylinders on the engine.

Here are the instructions it came with

If I had to guess I'd say the redline is not programmed properly in the new tach. Make sure you input the correct tire size and such and see if it makes a difference. It might actually be the CBs redline as measured at the motor but the tach is telling you 5500 when its actually 8k or w.e the stock redline is because the tire size is not correct

I have all of the settings as accurate as possible. I’ll probably have to end up buying a new meter. Would you happen to have any suggestions on a small digital meter that shows everything the original does (Speed, tach, fuel, gear, etc.)? The reason I changed it from the stock meter is so it could have a really low profile.

I dont have any experience with those i prefer analog meters myself. Im sure revzilla has some reviews on them though

Two questions come to my mind,
why did you change the gauge ?
when you say speedometer, you’re referring to the rpm gauge, right ?
or did you replace both “clocks” ?

I used to work for a company that made digital instrumentation, but nothing that would be practical for a street motorcycle. I get that it wants to know the number of cylinders so that it can take the ignition pulse signal, and correctly parse it out to determine an accurate RPM.

The tire rollout measurement would allow it to take the wheel speed sensor pulses to determine accurate vehicle speed.

Are you getting an accurate RPM? Doesn’t look like an obvious function for setting the redline based on what the RPM reading is. Can you find a YouTube video for that model of display to see how it is programmed? A generic programmable digital dash that isn’t specific to a particular engine usually takes the ignition signal and displays RPM, but allows the user to determine the redline as it doesn’t know what particular engine it’s getting the signal from.

If you aren’t too hampered by budget, you might take a look at what AIM has for your application.
