Check the IAM bolts, one of the Brits (fan or twit) has had similar issues when the bolts were only very slightly loose.

Thanks for the suggestion. Although one of the IAM bolts was loose in the past, after tightening, it has not moved.

Britfan60 had the "crazy/wild" idle problem that he traced back to loose IAM bolts.

Surging at partial throttle openings could be an issue with the throttle position sensor.
Check the TPS connections.

If the surging is that bad, you know the ecu is having trouble, and is issuing fault codes.
Best thing to do is get an OBD reader to check for ecu fault codes.
Readers are inexpensive, and the codes will help you to narrow down the potential problem(s).

The TPS and the connections were checked earlier this month. Everything still looks good and clean. Thanks!

Thanks for the photo and recommendation. $21.49 + free ship on Amazon. Sounds cheap enough but has this tool actually resulted in solving a problem for you with the 961?

Yes. Helped me find I had a cylinder head temp sensor issue.
It's not a perfect solution though, it just helps to reduce your search for the actual problem.
But it beats the usual; try this, then that, then something else, so on, and so forth....

My ecu keeps raising the crankshaft senor error, I clear it, go for a ride, and ecu reports it again, and again.
Bike runs fine, so don't know what is causing the fault code.

Sounds good. I'll give it a shot. Thanks again!

As BritTwit says, the issue is probably the ECU. Mine had similar issues and after 4 weeks of testing sensors etc at Norton HQ they replaced the ECU which “seemed” to solve the problem.
Was just hoping it might be something simple for you first.

Pretty sure they all do it. It's nothing to worry about it's probably just a ECU configuration issue. Mine showed the same errors. https://www.accessnorton.com/NortonCommando/dominator-ss-owners-journey.20224/page-4#post-301538

It may simply be a bad sensor feeding erroneous data to the ECU.
The OBD reader will see any fault codes that the ECU has raised.
A sensor could be bad, or possibly the connection between the sensor and the wiring harness could be corroded resulting in a connection.
The fault code will tell you where to start your search.
 
You probably have the SC ECU so at least you can use a ODBII code reader . If you had the OMEX ECU you would need computer , software and cable .

Tony,
Didn't realize that.
The OMEX module doesn't have an OBD2 connector?
Bummer!
 
Upon finishing the SC to Omex ECU upgrade , your ODBII connector becomes unused . There is a 9 Pin serial connector on the Omex that now becomes your access port. I have never looked CLOSELY at the 2016 and newer machines , I think the ODBII connector may be gone entirely from the harness ! This would not be an issue if we all had the computer/software /cable to do this. It was nice to be able to use the inexpensive ODBII scanner to read and reset codes. Maybe Richard-7 or iwilson could fill us in on this.

There are OBD2-Serial connector cables available on the market.

I wonder if the OMEX unit is compatible with OBD interface.
Should be, since OBD is a worldwide standard.

Hello Richard-7 , Are you still getting the backfiring ? Is this since the change to New Omex and Omex Map ?
Click to expand...

oh no. All great now. I have a new custom map. Next time you’re up my way I’ll load you up.
 
Thats great , But I have the original SC ECU . I need to get an OMEX and have it on hand . Then we can install the new Omex single seat bracket , OMEX ecu and then load up ??

The continuing saga...hooked up the OBD and got 2 fault codes, 0335-Crankshaft Position Sensor A Circuit Malfunction and 0340-Camshaft Position Sensor A-Bank 1 Circuit Malfunction. Are these the same thing? Anyway, I re-installed the "original no-name" Cam Sensor that the bike came with. I had replaced that sensor with the Made in Germany Bosch version when I first bought the bike. I hooked up the OBD again and NO FAULT CODES! Whoopee!! Not so fast, this is a Norton 961 after all. I started the bike, it cranked right up and idled just fine. I shut it off, hooked up the OBD again and, lo and behold, Fault Code 0340 comes up again (no more 0335) Unfortunately, I can't take the bike out for a spin as it is dumping rain outside at this time. Any ideas out there?
 
I'm still wrestling with the same codes 0335, and 0340 on my bike.
Bike runs fine, I clear the codes then go for a ride, come back, and find the same codes again.
I'm thinking that this state may just be a peculiarity of the SCS Delta ECU or how can the bike run so well with the ECU receiving faulty sensor data?
Forum member lcrken has had similar experiences.

I would take your bike out for a short bike and see what happens.
Not farther than you're willing to push the bike back home.;)

They all do this it's nothing to worry about. Just a configuration issue with the ECU. Has no effect on performance etc.

Here's mine.

OBD configuration page - as you can see the error reporting for those two codes is turned on for 'reasons'... Maybe drop an email to SCS Delta.
