MAP TALK

Fired right up first time and idle was spot on. Seems that that flat spot I had around 3700-4000 rpm is gone. Come on spring!!!

Awesome! :mrgreen:

I just woke up my bike, probably too soon, but it's been really warm in the mountains of Utah. Had the ecu reflashed with map 90 over the winter. My bike has the DT pipes but still retains the cats.

Great.
Pretty much my experience as well.
My 961 has Dominator silencers, and SBN decatted X-Pipe.
The #77 map helped surging and flat spot issues, but did not do much for the cold starting, and idling problems.
The #90 map fixed everything.
The bike now cold starts, idles, and performs like a modern EFI bike.

I have a feeling I'm gonna be jealous. I need to be sensible about it, however. I have to determine whether my warranty is going to be necessary before I go and void it. :roll:
 
I would suggest that you do not void your warranty.
If the #77 map is acceptable to you, and it does help with some issues, then stick with it.
You will preserve your warranty coverage.

My dealer advised me that the #90/91 maps were only supposed to be used for the Dominator/Dominator SS models utilizing their special exhausts.
The claim is that the rich mixture in these maps would cause a breakdown of cylinder lubrication on other models like Sport/SF/CR because of their more restrictive exhaust systems. The unburned fuel would wash the oil film from the cylinder walls.
I don't disagree with this logic, because it is essentially correct.
An overly rich fuel mixture will have this effect on an engine.

However, my bike has a totally unrestrictive exhaust like the Norton Dominator model.
SBN Dominator silencers, and SBN de-catted X-Pipe.
Because of this. my 961 suffered from the effects of a very lean condition from day 1.
Using the original (Stock) map the bike surged badly at some map transition points.
So bad sometimes that I was concerned it could have resulted in detonation.
The #77 map thankfully, fixed the surging.
As I indicated earlier, installing the #90 map resolved all of the other performance issues with the bike.

FWIW, I'm not suggesting that others should do what I have done, only offering my experiences on the map/tuning subject.
 
The Dominator SS has the same stock exhaust as the Commando. The regular Dominator has the short sports exhaust same as available for the Commando. Only the Megaphone is specific to the Dominator SS/Domiracer. Would be interested in knowing what the differences are between the Dominator specific and Commando maps since the engine and exhausts are the same.
 
We have been told that the 90 maps are for the Domiracer not the Dominator and Dominator SS. Fred check your earlier posts, are you confusing the Domiracer and Dominator. Van Epps, Simon and SBN have all said the 90 maps were for the Domiracer which has the trumphet pipes as an option!

Bob,
I looked back to a thread from last year: Remap #90 experience
Simon does make reference to "models not yet available in the US" and says maps #90, 91, and 92 are for use on those machines.
I'm sure that wide open megaphones will flow a lot more gas than my SBN Dominator silencers, but the performance improvements I've seen from switching to the #90 map are undeniable to me.
Everything is vastly improved to the point where the 961 seems like a normal EFI bike now.
Easy starting, idling, great throttle response.
The exhaust has no hint of unburned fuel from an overly rich charge.
When the weather/temp improves I intend to run through a few tanks of gas to check the fuel mileage as well.

I plan to tolerate whatever issues are not addessed ... for a while.

The de-catted Motad pipes would be similar, no?

I will look out for this once I start riding in a couple of months.

Am I mistaken or wouldn't the Dyno break-in I paid for flush out issues like this from the start? And wouldn't the folks at MCC be able to adjust the injectors, if not the map? I remember reading somewhere here that the ECU data can be collected and observed, but not modified the way I can with the maps available for my Daytona 955i, for instance. It seems to me that an overly lean set up should be something one can change to some extent.

I have never done a Dyno break-in so not sure what that involves.
There is an app that allows you to see the engine senor data, but I don't think it allows any ECU modifications.
Until someone is able to get a Power Commander to work with the 961, the only way to adjust the injection mixture is by swapping factory EFI maps.
 
Sorry, I should have made it more clear to what I was responding to. The 961 engine is shared on all models of motorcycles made by Norton; so far.

So there are three maps for the commando line up and all models of commando have the same volume airbox and they are the stock map and the two performance maps that match the exhaust you are using.

Then there are three maps for the domi models that are tuned for the volume of the domi airbox regardless if its a dominator or domiracer. Same scenario. A map that would cover the very quiet exaust and then the shortie exahust and then the race open exhaust.

Hope this helps.
 
I'm looking to clear this up. There are three maps for each model as we all know. But some say they have 090 and others 091

But for the topic of conversation here lets talk about domi maps on a commando.

Who has what map installed in their commando?
Domi stock is 090
Domi aftermarket pipes is 091
Domi mega phones is 092

Is 090 or 091 better for performance on a commando with shortie exahust?? Of course this would never be used on the street only on those special track days.
 
Its clear norton uk does not support domi maps on the commando. They have a few maps for the commando and I am happy with 77 on my commando. I just wanted to clear up this 90 vs 91 issue. If you are running any of these maps, against the rules, which one are you running?
 
I run 91 on my track days with no cats and either the SBN Dominator Sport exhaust or my homemade pipes which have similar backpressure! The bike runs great as a modern EFI bike should on cold starts, plug runs, etc, with no surging, popping , pinging, lagging, flat spots or any other issue. The plug runs and my exhaust analyzer and scans show the bike is fueling very close to ideal and much, much better then the stock map and much better then the 70 series maps! :D

Hello Contours , Just speak to Bob in service. They probably broke it in on the stock pipes and Map. Then they set you up with your new exhaust and map. This will also come with a dyno report just like mine. Don't worry just call BOB.. Tony
 
Alright, Tony. Bob and I have exchanged a couple of e-mails at this point. If you trust their judgement over there that's good enough for me.

The only question remaining is the Oil-in-the-airbox fix. I would prefer not to worry about that when i pick 'er up. :)
 
Hello Contours , The oil in air box fix is another matter. I don't know anyone in North America who has this done yet. There is a method for getting on the list and this will involve getting the actual discharge rate over a period of time and filing with the factory. They probably won't do it new in the box like your bike. However it can't hurt to try . You better ask Bob. Also, lets ask Richard maybe Canada has done this already. But like everything Norton this will take time so please be patient .. Tony
