Connected to ECU's and Balanced Throttle Bodies!!!!!!!

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.

... but if you look on Page 5 of this thread, you will see the 2014-2016 six-pin MOLEX connector (a diagram of which is on Page 1) AND the 4-pin cannon-plug style connector used on 2017 and newer Urals to obtain OBD-II diagnostic information.
Might be time to sort this thread out into a shorter guide that sets out the steps for OBDWiz, the Connectors and how it works and split questions off to another thread? (and yes I know just how painful that would be as an admin, but I think the topic warrants the attention)

Not a bad idea. Might have to confer with my associates on how to effectively accomplish this. 🤔

I cannot get my OBDLink SX to work. I'm sure now after several checks that the pins are right. I made up the adapter cable and I have 12.3 v on pin 16 and the grounds show 0 ohms resistance at the female plug before connecting the OBDLink SX cable from my PC. Same values at the bike round OBD plug. The OBDLink SX cable LED stays yellow when connected and the OBSWiz software can't communicate with the bike.

I checked the OBDLink SX cable on my VW Tiguan and OBDWiz connected just fine and the cable's LED was green.

I could make up a new adapter cable, but I'm afraid that the result would be the same.

I'm at a bit of a loss as to what to try next.

I'm starting over! Ordered new cable & plug parts. I suspect that there's some sort of issue with the original cable.

I finally got my cable to work.

First, I had been overthinking the problem of making up the adapter cable with the female plug. What is pictured and labelled "chassis plug" in the instructions is actually the female plug (same as OBD2 plug in a car) at the end of the adapter cable that you must make. I had the connections reversed.

Second, I found a broken wire in the adapter cable that I had made. Be sure to check continuity of connections if you encounter a connectivity issue. I had done so, but the wire broke after that, probably when I first plugged in the round plug.

Finally tried connecting mine up, and eventually managed to make it work.

I'm using OBD Fusion on iPhone, and this: ("OBD II Wi-Fi Interface")
-
-
OBD Fusion_2721_2722.jpg

It's linked to 'phone as Wi-Fi, and for OBD Fusion as "OBDLink MX Wi-Fi"

At first I kept getting "Not Connected". Eventually I realised I had to tap the "Connect" word at bottom of the screen! Image

Then there was the hiatus of finding which "Device" setting works. (OBDLink MX Wi-Fi)

There was a lot of connecting and chundering going on, then it reckoned it was ready, and sure nuff it seemed to have downloaded a page of diagnostics (mostly, no error codes).

The vacuum max. scaling is too low so I found out (eventually) how to change it - touch and hold finger on the dial picture and the properties window appears. So upped it somewhat.

Anyhoo at the moment I've merely established that the idle is 900 rpm and the throttles are equal.

Does anyone know if the OBD2 cable used for the 2018 work on the 2019s?

The OBDII cable is used to balance the throttle bodies and the new Kehin's have vacuum ports so OBDII has become a bit redundant. Fault code finding with OBDII is very hit and miss and only points you in the general direction of the fault area, as the displayed codes do not correspond.
Based on that my guess is no?

I might hazard a wild guess that since the Keihin system is completely diifferent then so is the connector and the pinouts. The Electrojet set-up went thru two different OBD port connector configurations.

Thanks to this forum and information, I crafted the cable for my 2017 Gear Up today.

Nevermind that I ordered the parts over 1 year ago, and had them sitting in the closet for the longest time. :shock: I figured that I needed it for the next service I intend to do tomorrow.

I took my time, use some old fashioned extrapolation of the technique in the video and made the changes, in my mind, for the 2017 connector differences.

Worked like a charm the first use! I'm thrilled.

I even tried my hand at programming some custom user screens, and I like the program. I bought the TouchScan, + Professional Add-on, from the obdsoftware.net site. I have a Dell touchscreen Windows X laptop specifically for all of my other motorcycle ECU software.

So my heartfelt thanks to the original author of this information! My gratitude for a job well done Sir!

I do have one question that I haven't found the answer for yet.

In my PID definitions, there are both Metric and English units. On the layouts I designed, they defaulted to the English units. How do you switch it to the metric display, so for example, you can see pressure in kPa versus psi? Is there a quick toggle or keystroke to do this? I search the help database but found nothing.

Thanks in advance!



UPDATE: Found it. It's under the GENERAL tab in the software. :D
