I see this note , you must have it. You can ask SCS to be sure. Many here have plugged the throttle body passage between the throats. Turn off the Idle air control in the ECU wuth SXTune and set the idle manually with the stop screw . Many here have done this with excellent results , myself included.
 
Thank you for reply.
We recognize that the IAC valve is an important part for stable idling, so
I'm surprised the IAC valve needs to be removed.
I have contacted SCS, so I will wait for SCS to contact me. (New map and response method)
If it still doesn't work, I would like to delete the IAC valve.

Do you know how to deal with Overrun's afterfire (2000rpm)?

After checking "Overrun Fuel Cut-off Variabes",
Upper RPM 2500, Upper RPM 2000, so
I thought this was suspicious, so I set the PRM to 7000~7500, but
There was no change and afterfire occurred at 2000rpm.

I'm waiting for your reply.

Is this decelleration popping (decell-pop) with the throttle closed ? The throttle body throats blocked may solve this also with the over rich condition caused in the other cylinder with mixture robbing and O2 sensors trying to compensate .
 
Thank you for your reply.
yes. Popping of deceleration.

I will check the points you have pointed out.

thank you!

I just purchased 961 and there are many things I don't understand.
This forum is helping me.

I'm sure I'll ask another question, but thank you in advance!

Sorry for the numpty question but is that under Idle Speed Control Variables and set the Stepper Motor to disabled?

Yes , that sounds correct. You can check the function of your TPS in SX Tune . Are you using SX Tune ? You can try setting back all of your changes in the ECU to original. Do not disconnect the TPS . So functions may not be availible in locked SC Typhoon ECU . Is this a SCS Delta 400 ?

Thanks Tony. Yes SXTune with an unlocked SCS Delta 400 (the larger bodied one).
I last posted on this thread in Dec 21 and the bike has been sitting untouched and only half sorted since, life got in the road. Thankful that i had posted on here as it is a good record of where i was at.
 
I purchased an SCS Delta 400 on December 2022 and from that moment on I could say I realized at least 100 different maps with relevant road tests.
My experience with the SCS software is now really huge and I believe any modern Norton owner should enjoy on such modifications.
So far I run a map that is really much better than that I originally received by SCS, mainly targeting smoothness running at low-medium rpm and quite linear curves approaching without excess of engine braking.
The 'hardware' configuration of my bike (SE my 2013) is the well known, substitute whatever shit chinese parts must be substituted, no catalyser, open exhaust, IAC valve elimination, obstruction of the connection channel between the intake valves in the throttle body and others.
I'm so deeply satisfied that I'm thinking about a possible business about.

That is good to hear. Can I ask what is a business about ?
 
Tony indeed I'm just thinking and absolutely not sure. I mean I'm an engineer and spent a lot of my pleasure time to develop and test maps gaining a beautiful result, at least in comparison to what my bike was previously.
So I would target somehow a return of expenses and efforts made. But I perfectly understand that it is difficult, if not impossible, to economically valorise this type of work. However, if anyone is interested in trying one of my most recent mappings, contact me privately with an email address and I will send it to them for free. I am very interested in your opinion as Norton Commando 961 experts.
Obviously it goes without saying that I take no responsibility for how it will work on your bikes, since we all know that they are all different from each other! However, I recommend that those who want to try it have the hardware set of the motorbike that I have described

I like this idea.
 
I sent yesterday to Tony my latest map. His bike is very challenging for my map since it has a full air inlet without airbox and my map is not developed on that conditions. However I'm confident he might appreciate the smoothness at low rpm and small throttle opening. As I said I worked a lot on that.
Whoever is interested to test as well it for free please PM me with an email and I will send it ( a .cal file) to you.
Tech preliminary condition implemented to my 961 SE and important to test the map:
1) having an SCS Delta 400 ECU programmable (only needed to upload the map, one minute work). Essential
2) having eliminated the IAC valve, setting the idle with the small bolt on the right of the throttle body. Essential
3) having closed the port in between the two inlet valves to avoid stealing. Essential
4) having eliminated the lambda sensors with the proper plugs. Not essential since my map eliminates the lambda sensor closed loop control by the software
5) having BMC filter and open exhaust, might be not essential but better condition
6) having replaced all the china OEM shit with good devices, mainly coils, plug wires, injectors, air and coolant temperature sensors, cam sensor etc. Essential

You guys are all over this setup, which is great! Some advice if I may.

I’m delighted with the way my 2015 CR (Omex) is running in ever respect, less tickover when the bike is warm.

Cold she’ll start and tick over like a champion. When warm however, she still starts and ticks over initially, but as the ride continues, the bike will semi-regularly stall as she drops to tickover. Because I never know when it’s gonna happen, I hold the bike on the throttle at junctions etc. I’m used to this but it does detract slightly from the ride.

What would be the minimum required to resolve the tickover issue alone? Can I hope to achieve stable tickover by simply removing the IAC valve and setting tickover as described above? I live in a warm climate.

Advice is gratefully received from those with dirt permanently lodged under their fingernails😁👍!

Hi Stephen , Do you have the locknut on your throttle set screw ? With the omex you probably can't see what your closed flaps voltage is (tps) . Have you tried cleaning the idle motor plunger and cap ? Have you ever replaced the Idle Motor ? Maybe a bit more open on the closed throttle valves with the set screw ? (1/8) turn ,.
 
Maybe another option Stephan is to try a new IAC…? I had good results( although not perfect) after I changed mine. Better idle rpm( when the engine is warmed up).

Apologies - just realised I’ve highjacked the Delta 400 user group thread:rolleyes:!

To be honest Tony the bike’s behaved that way for longer than I can remember. I had it in mind that I would need to go through the process - remove the IAC valve; blank the TB port; possibly remove lambda sensors etc etc. Seemed like a golden opportunity to screw up a bike that was running beautifully, less occasionally unstable tickover (now pretty constant and getting more intrusive).

Easy options first though, as you (and Charlotte) suggest. I’ll clean/replace the IAV assembly and re-assess - posting outcomes on a more appropriate thread. No access to ECU readings. No locknut on the set screw.

Thanks for the advice - as ever.

My next step will be fitting the bike with headers properly equipped with M18 threaded bungs to locate wide band Lambda sensors. Targets are twofolds: on the simplier side I will get from a proper gauge temporarily installed on the handlebar info about the real time Air fuel ratio to implement afterwards modificatins offline in the ECU.
On the more difficult side, since it will need also wirings adaptations, I would need to test the fuel close control loop by wide band sensors working, being it a routine present in the SCS Delta 400 software.
Stay tuned :)
 
I'm finding difficulties to do the above test since surprisingly I have been aware that the gauge+the controller need a 6A power supply, at 12V of course.
And even more an insulated supply (with a specific relay circuit) derived from the battery to avoid EM interference.
Of course this make everything more and more difficult.
