How to make a 2017 and up tachometer functional.

Woe unto you that bought the first model year of a major remake, perhaps this section can help address any 2014 and later model Ural "imperfections". Here's a special section for folks with the latest rigs to discuss 2014 and later model-related topics such fuel injection, 3-wheel disc brakes, hydraulic steering dampers, spin-on oil filters and other anomalies that don't belong on true Russsian motorcycle ;-P We've gone from using big hammers and greasy wrenches to needing computers and Ouija boards in order to fix our rigs.
Forum rules
Please keep this section specific to issues pertaining to 2014 and later models such as fuel injection, sidecar and rear disc brakes and so forth. Ask general or non-2014 and later specific questions in the main Hammerin' & Wrenchin' section.

What did you set your shift rpm to?

Barry, if you wouldn't mind reading through this thread and adding anything you find missing. I'm trying to make a dedicated speedometer thread for trouble shooting purposes.

Good thread, wish I had found it when I first got my rig, would have saved me some head scratching.
Looks good so far, still in the learn mode myself, if I learn something I can contribute I certainly will..

Thanks, I wish I could figure out how to keep it nearer to the top of the list so it would be easier to find.

What is the ideal shift rpm? And what is red line rpm?

A word of caution for anyone making this modification. Cut the wire going to the speedometer (yellow or blue/red after the connector) don't just splice into it.

There's another way to hook it up that's the official, unofficial way to do it.

Simply hook the jumper wire to the loose gray wire with female connector on the speedo.

Well I wish I new that before I started! What jumper wire? the one from the coil?

Yes, the wire that goes from the speedo to the gray/white wire on the coil, or wrapped around the spark plug wire.

fWIW, the way you did it works fine too.

Well I'm still on the steep side of the learning curve when it comes to Urals. Getting a working tach on my rig has been worthwhile. I've always owned Harleys and am in the habit of using their torque to get where I need to go. I'm definitely not used to the relative high revs the Ural needs to make power.
So with a tach I've already found that it is easy to overrev the Ural in first and second gear. More importantly, I'm spending a lot more time in third gear with the engine singing it's song and moving right along!

That shouldn't be a concern for folks with mid 2017 and later rigs with the upgraded, matched FD gear sets.
is there a way to know whether my 2017 has matched FD gear sets? by VIN perhaps?

That's probably the only way, and even then it might not be certain as it was rolled into production mid year.

Re: How to make a 2017 tachometer functional - a probably stupid question

Post by Mike_from_Germany » Fri Jul 20, 2018 8:43 am

Hi alltogether,

I am just trying to make my tach working. I read this thread and searched for tach and "gray wire" but I am a little confused.

There is a yellow wire coming out of the Acewell which is connected to a blue wire coming from the ECU (according to the wire diagram which I think is not absolutely correct).

In the first post Burt1713 says I should disconnect this. My question: What is it for? Did they install a useless wire? Or what?

There is a grey cable with a female connector coming out of the Acewell. I found that this is a high-resistance input, Acewell says it should go to the ECU/ignition coil. Does this mean I can simply go this way and forget the first step of Burt1713?

Is there a pinning of the ECU around? This would probably help.

And my apologies for my english, I hope there are not too much mistakes.

Best regards, Michael

I've hooked it up both ways, and both work. The simplest and most functional way is to run a wire from the gray wire on the speedo to the gray and white wire on a coil.

I believe the wire from the ECU to the yellow wire on the speedo just provides a signal to the hour meter.
