My dad plugged his in today and bike started and idles great. 2013 SE SC ECU. TOMORROW he’s taking a highway ride to pick up a few more fork seal kits from Ohlins for stock. So that will be a nice test for the lambda delete plugs. About 1.5 hrs each way. Could have had them shipped but good excuse for a test ride.

Ok, found it. It's even labeled. But fuse was fine...
Often just means the fault code in the ECU has to be reset. Many cheap OBDII readers can do this. Your local auto accessories shop will probably sell them. But recommend buying a bluetooth OBDII reader on-line, very cheap you just need to install an app on your smartphone. Just plug into the OBDII plug located near the ECU.

Richard have you tried unplugging the simulator yet to see if it makes a difference?

Not yet. Rain here. Tomorrow should be nice. I’ll give it a few weeks of riding first and then I’ll try it. Canada man!!! Limited riding weather.

My brother lives in Thunder Bay before that Whitehorse. Don't understand how you can say it's spring when you need to cut a four foot deep hole in the ice to get your line in when fishing!

Yes, I tried that with my car OBDII dongle (it's an old PLX Kiwi), but couldn't get a readout from the ECU of the Norton.
Which dongle do you use/recommend for the Norton ?

Because in winter they need an 8 foot hole!

Chaps, we seem to have mixed results here. I’m not sure if I’m right, but it seems like earlier bikes respond well to the lamba delete and newer bikes don’t.

Is that the case?

Do we know why?

Different programming in the ECU probably. Earlier bikes might be programmed to just switch to open loop if no o2 sensor detected without any fuss. Later bikes might throw a fault code and the ECU switches to a fail safe limp home map, which will be pretty awful.

ELM327 based reader (just google it). I've used this on mine with success. However Norton changed my ECU from an SC to an OMEX and inserted a length of hybrid harness to get everything working. My OBDII plug stopped working after that... But that was probably something to do with the hybrid harness.

Normally, my kiwi dongle should support ELM327. Might need an other app on my phone then. What are you using ?

Not sure if the OBD11 Will connect to the Omex ecu.But it did connect to the SC ecu.
My bike had the upgrade from SC to Omex and there was a different plug and software to connect.
Attached photos of TSB for connect procedure.
This allows loading of new maps and diagnostics.

The software is free download from Omex website.
You should be able to remove stored EML codes with this.

Cheers
Paul

Pretty sure it will still have an OBDII plug hanging off the harness somewhere. The ECU can have it's own plug for programming but it's the law for any vehicle sold in the US to have an OBDII plug. This is so any workshop can use a standard plug to read diagnostic information from the ECU without requiring proprietary cables and software.

That's right. There is a OBD plug under the seat. But when I tried to connect my PLX Kiwi dongle, it couldn't get a read out from the ECU. Maybe the app was the problem so I'll try other apps tonight.

But can you order all the needed parts (and software) from Omex, as an individual ?? You surely need the maps from Norton ?

Yes maps from Norton.
But they are locked and cant be changed.

Omex have the map4000 program free to download.
The rs232 cable was from ebay.
My OBD!! plug became redundant when the ecu was changed over.

Probably not .
Just Like Omex wont comment on their ECU if you contact them.
This shows you what you need to hook up to the ECU for Diagnostics.
Tried hooking up, no problem connecting but you can't go any further without the configuration files contained in the 'omex dealer page.gwpkg' file that is referred to in the tech bulletin. See the screenshots below of what happens.

If you want to read more about the ECU you can read through the installation and tuning manuals at the following links.

http://omextechnology.co.uk/600 ECU Installation Manual 2v01.pdf

Broken link removed

On a side note I see the cal file in the bulletin is for the V4 Norton...

So far my bike and my dads bike have been running excellent with these plugs. Anyone else have some feedback?

And thanks for the recommendation to everyone who worked together to figure this out.
