...What firmware , calibration version are you running?

Hi guys,

In an effort to solve hunting/idle problems.
Dealer worked with Norton (apparently) and has put in what I think is newish firmware with older calibration file.

I have a Omex ECU.

File versions:
6500101_R1 V2 Norton Commando Aftermarket Exhaust. OMEX 630.01N31

Starts easy.
Runs rich (you can smell it)
Mid range and power all up has gone backwards.

If you have an Omex and are happy (with Norton long open pipes) what files and version do you have if known?

Best.
 
GK I have an SC ecu so I can't help much. What year is your bike. It appears to me you may have the 2016 Aftermarket map. I cannot help with the firmware numbers. I bave the 91 map andI I am happy!
 
Hello GKryder , Iwilson has recently done the NEW OMEX upgrade to his Domi . I think his bike is a 2015 with SC ecu as original. He said he would report on the power after a dyno run. His feedback was positive and so much so that he wanted to get the dyno readings. I have a SC ecu on a 2014 Sport. It has been given the latest download OS that came out in early 2016 for the SC ecu . I am running the Motad short/loud with de-catted x-pipe. I also have done a dyno run after that and am happy to report a 2 bhp increase across the rev range. And an increase in torque across the range ! So , I am disappointed to hear that you have gone backwards. I have posted the before and after graphs on the site. So do a search if you want to see. Can I ask what the bike was running before the download ? Were you unhappy with it before ? I will try and get the map number but it is for SC ecu so wont help you presumably. I hope Simon reads this and set the matter straight.
 
Hi. I have an omex fitted on my Mk11 and did suffer with the hunting problem. But there is a new mapping that Omex have introduced in conjunction with the Norton Factory and my Bike. They used my bike as a test piece. It now runs perfect.
I am assured that your local dealer can get access to this new mapping software.
Good luck.
 
Hi gents,

BIKE
2015 sport

PREVIOUSLY
Had SC ECU.
Throttle body issue
Hard to start and would idle high when warm (over 2k)
Good power

THEN
Changed to Omex
Easy to start
Hunting
No real high idle but sometimes fluctuates
Good power
Better than before at higher revs

NOW
Newer style throttle bodies again
Easy start
Good idle
Some hunting at part throttle below 2K
Poorer mid range
Poorer top end

Dealer notes.
Norton does not have maps sorted yet for open pipes.
Idle circuit is part of problem.

I would have been happier at the THEN scenario.
But will revisit.
Wish more people/dealers could do this - have access to Omex ECU and help Dyno tune the girl.

Thanks to all the feedback.
Not too far from grace.

Might do some *Italian tuning.

Regards.

*Rev and ride the snot out of it.

Yes I can confirm most of the above. I haven't been back to the dyno yet but it's on my to do list and slowly rising to the top. But I can confirm with 100% accuracy that the bike now starts and idles, hot or cold with the kind of certainly you expect of any modern engine. It has not stalled on me ONCE since the bike was switched to the OMEX and current map. It should make zero difference regardless of your exhaust/airbox combo, unless you're not using O2 sensors (but even then their input is usually ignored on startup until they warm up). If the rest of the map is as good then I expect to see a more consistent graph if there's a couple more hp then all good. But it always had enough for a bit of fun through the twisties without propelling you into the scenery if you sneeze.
 
Hello iwilson , thanks for the feedback.
Hello GkRyder , what is Italian Tuning ?
 
Hi, the bike I just bought has an Omex ECU in it. I've had to pull it out to send it back to the dealer for a new map. When I bought it I had them fit the long open silencers to it but they never updated the map at the same time. The bike runs lean as buggery so it needs a richer map put into it.
When I pick it up I'll find out what version it is and let you know what the bike runs like.
 
Just heard from the dealership- they want to have access to the whole bike as opposed to updating the ECU. Not sure why but it's a pain to deliver it 800Ks to them.
Will keep you posted.
 
Hi Kiwi961

Sounds like they want to hook it up and have Norton checking remotely while running as well.

Which what my dealer did.

Or wish to see if throttle bodies part of any issue or in need of upgrade.
 
Hi All,
Just heard from the shop yesterday. They put in what they thought was the correct map and it ran rough with stutters at take off and again at 3-3500 so they put the old map back in to compare and found it equally as bad. After that they rang the agents in Australia and got sent a different map which they reckon runs okay.
Just waiting to have the bike sent back to see what it's like.
I'll keep you posted
 
I've got the bike back and did a hundred Ks on it over the weekend. It runs a lot smoother at lower revs and can pull away easily from about 2000 revs which makes it a real joy to cruise along on. It seems smoother all round, I don't think there is any increase in horsepower but there is no longer that jitteriness when rolling on a bit of throttle at low revs.
There is still a bit of Jarring at about 3200 in some gears but overall pretty good. It also started easily and idled well straight away except for one moment when the engine stalled as I was coming up to a red light when it was still a bit cold.
The next thing is to get some work done on the pipes. I ordered the long open pipes when I bought it, but they aren't the monad ones - they are a different manufacturer from Aussie which is where the New Zealand bikes come from. They are still pretty quite and not really a straight through design. There is a local guy who does wondrous things with pipes so he's going to cut it open and do some surgery. Let's see how that goes
 
Just bear in mind that you run the risk of ending up with engine characteristics that may mean no map is right. In saying that even the factory maps despite recent improvements are not perfect, although at least the startup and idle are now sorted.
 
The pending new Power Commander for the 961 will be the best tool to adjust fueling for the 961's running modified exhausts.
The factory is simply not going to spend the time and capital to develop better maps for open exhaust systems other than the systems they sell.
My 961 CR with SBN de-catted exhaust currently uses the 090 factory map, and runs well, but could certainly use improved upon.
There is sleeping HP in the 961 that the PC5 can release.
 
Hi - do we know for sure that Power Commander are going to make a unit for the 961s. It would solve a lot of problems that's for sure
 
No, there is no guarantee though it seems a few German users already have one working at some level!

There was a posting on the forum a few months ago by a member who said that the British subsidiary of DynoJet UK was looking for a 961 to conduct tests on.
DynoJet indicated that this was in preparation for the release of a PC for the Norton 961.
I haven't heard anything since, but I'm keeping my fingers crossed.
 
Hi I spoke directly to the research team at a show and was told that they were seriously looking at releasing a PC for the 961. They also spoke about a bike for testing. Despite several emails, including one a recent as last month, to them they have not responded since. Doesn't therefore look like it will happen anytime soon.
 
Hello , I have never used a power commander . Does this unit plug in to the current ECU ? Does it need to be cut and spliced in ? A clean plug in would be great. Is it then adjusted by means of laptop or tablet through a port ? Does it make sense then that the different types of Norton ECU complicate matters for them ? OLD OMEX , SC , NEW OMEX ? And it is only 2017 !!! Does it also make sense that this unit when fitted should be done on a dyno to see what is actually happening ? I suppose that Dynojet will have to do all of that on the donor bike . I just see complications for them with the different ECU's and the low numbers of bikes . But the bright spot here will be for the ones willing to try it , means more performance and better running hopefully. I have been told by a Triumph dealer in my area that they have gotten good gains across the range from the EFI Triumph Bonneville 2008 to 2016 with K&N clamp on air filters and a tune of the ECU. I don't know if this involved a power commander or not though .
