ECU Programming!?

[jim shea]

I have just learned that if you want to put a used set of Termis from one bike to another the ecu is coded to a specific bike and can not be used on another bike!!! I have seen a lot of posts about fitting Termis, but this issue has never been mentioned! Apparently the ecu can not be reprogrammed! and in my case, taking a set of pipes and ecu from a M/strad 1000 to a M/strada 1100 can not be done? even if you remap the fuel using the std 1100 ecu, it may be that the engine will run too lean!
Any comment splease?
Cheers,

Yes the ECU is coded. Once it has been fitted and used on a bike it cannot be reused on another bike. This is the same on all the Ducati range not just the MS. It gets discussed plenty on the Monster forum. The reason they do it is to reduce theft of the bikes. If someone nicks your bike then they not only need a new ECU and keys but new clocks and locks too. Fine in theory but a pain in practice.
One option, if the cans from the 1000 fit the 1100 is to swap them over but sort the fuelling using a Power Commander. This is what I did when I fitted the second hand Termis from a Monster S4R on to my S2R. I junked the used ECU and fitted a PC. Total cost of the PC, fitting, and dyno set up was about £400. FWIW, I think fitting a PC to a bike is a good move anyway if you can stretch to it as it remaps the fuelling specifically for your bike and can often sort out flatspots etc. With open cans, open airbox, cat removed, and a PC fitted I now get a much better throttle response, more mid randge power, and another 10 miles out of the tank too.

Interesting

whats the deal with the ECU. can anyone explain exactly what happens to the bike performance by changing the mufflers to termignonis? why does the ecu have to be altered?

thanks for the insight

You can buy a power commander to overcome this. Plenty of people buy Termi's and then run a standard ECU and a power commander.
Apologies i had'nt read the post by Gilps :[

Gilps,
Thanks for that, the PC may be the only way to go.... or, decat altogehther.. see the link below.

Vasco,
My simple understanding is... when you change the cans, air filter etc to allow more free flowing pipes,for noise or performance you will make the mixture run leaner, therefore you need to remap/refuel to allow for that...otherwise a lean running bike can do damage to the engine!
Hopefully,a much more technical person will respond with more on this subject?

I don't know if this company can do any work on ecu's but might be worth giving them a call.

That's exactly it. The standard ECU is set up at the factory with a fuel map to match the standard set up. If you then change the exhaust or open the air box then the fuel mixture will need adjusting. The replacement ECU is supposed to address this as it has a revised map on it. However, where the standard map is a one-map-fits-all solution for all stock set up, so the new ECU map is also a one-size-fits-all map for open cans etc. It is far better to set up something like a PC as it will be set up excatly for your bike, not some generic map with is roughly about right for your bike.

This will fix the reverse of this problem. If you have a stock ECU programmed to your bike, and you've got the keys, but your clocks fail/break, then you are stuffed as the key/clocks/ECU all work together. No clocks equals no go as the ECU will not recognise them. You now need to buy brand new clocks and ECU. This is the idea behind stopping bikes being nicked as it is about £800 to replace everything. At least that was the case until David found the company mentioned in that link. They can morph your existing clock's ID on to a replacement set, perhaps from ebay or a breakers.

So when you fit the Termis 'kit'; cans, air filter and a new 'race' ecu, how do they make sure that the clocks etc work; and what about diagnostics and so on.. is this the 'coding' of the ecu specifically to the bike that I have read about(and the red key)??

[Psychlist]

You can run race pipes on a std ecu so long as you still restrict the airflow by keeping the std air filter, you get the extra noise but "no" increase in performance. If you fit a K&N or DP air filter as well as a cat bypass with the race pipes then you can run a std ECU with a Power Commander and someone like W.M.Snell's can set that up for you no problem.
The pipes I had were for an 1100 Multi as my bike had a big-bore kit fitted (I understand the pipes themselves are the same for 1000/1100 DS engines anyway).

Thanks for the clarification. I have posted a new post re how the clocks, immobiliser etc would work with a new ecu.

Yes it is. You get a new ECU which is then programmed/coded/mated to your clocks and key. Once that is done it will not work on another bike.
