961 ECU

Hi all,

Looking for a bit of advice... maybe Simon Marshall if you're still around?

When my 961SE recently went in for its service, it was discovered that my particular model (2010/2011) turned out to be un-mappable. Apparently, it was the models *after* mine that were adjusted/updated for mapping capability. Another problem encountered was that the 'tick-over' was unfixable. My particular 961SE has to be warmed up a fair bit before the throttle can be left with it happily ticking over by itself.

It occurred to me...

Supposing I have the ECU changed to that of a later model...?
Can it be changed?
Would this fix it to become 'mappable' AND sort out the tick-over problem...?

Regards

Very good question. I want to say "yes", but why hasn't it been offered to you by now?

From my experience with my Daytona I discovered there are two different versions of the ECU over the span of 10 years and they are not interchangeable at all.

I had a 2011 SVA (single vehicle approval) pre euro 3 bike with an Omex Ecu that was remapped by the factory. It may be that your dealer wherever you are does not have the equipment nor the maps for that type of Ecu rather than the bike is not remapable. I would have thought that it would be a lot of work to fit a later ECU as I guess you would also need the later exhaust with Lambda sensors and other bits and pieces to work with it. Hopefully someone who knows more will chime in.

The engine has basically stayed the same. It is possible but I doubt it will be for free. Perhaps a phone conversation to the factory would get you the parts and you would have to do the work. Let us know how you make out.

If you change the ECU you will also have to update the sensors. Things like the cylinder head temp sensors, crank position sensor, throttle position sensor, and don't forget the latter models are closed loop so you will have to modify your headers or get new ones to fit the o2 sensors! Can you change the ECU , probably ! Will it be cost prohibitive, absolutely!

Thanks for all the useful responses.
Re BPHORSEGUY''s reply... well, that settles it. I think I'll stick with things as they are. :?

Hello Dan , Certainly get the Norton people to give you the last word on it though .. They may have something for the older bikes. Ask Simon Marshall.

Are you speaking from experience or guesstimating? I'm only guessing, but based on engine conversions I've performed in many cases the sensors are generic - not always but they are generally low cost items anyway. In my mind the hard bit is getting the wiring sorted together with the right plugs for the ECU. This can cost a lot if someone has to do it for you. The o2 sensors are nothing - it's very easy to weld on the correct bungs. I'd be surprised if Norton changed many if any of the sensors just because they switched ECU manufacturers.

I was talking about the wiring harnesses or looms also.
