Ducati Monster Forum

If anyone could help me this would be great!
I bought an 05 monster s2r 800 from a guy.  Originally I wasn't going to purchase the bike because he only had one black key for the system.  I told him I'd buy it if he replaced the ECU.  So he did.  I road it and checked it out.  The ECU seemed to have no problems as far as I knew.  It did stall frequently and didn't ride smoothly so at the time of purchase he took another $300 off.
I bought it...took it home...and it still continued to stall and not run great.  When I took it to the dealership they informed me that the ECU was not for a monster at all but for a multistrada.  They suggested I replace the ECU...but I really don't have the money to do that.
Will the multistrada ECU be a problem for this bike?  Any insight would be great.

I'm pretty sure the multi was never an 800. Def cause for a lot of problems.

You could bandaid fix the situation w/ a custom dyno-tuned pc3, starting w/ a map from a multi.. It would end up costing you  around $500-600 all said and done.

perhaps it's time for a DP ECU specific to the S2R 800.

good luck

Q

Thanks.  I'm trying to figure out what to do while spending as little money as possible.  I just want to be able to ride the bike without problems...and I obviously don't want to do damage to the bike.

Can you post up what markings are on the ECU?

Do you have a red key?

I do have the red key.
The ECU says "MTS 1000"

Very good that you've got the red key.  :)

If that really is an MTS1k ECU, yeah, it won't run well.
Ducati isn't particularly diligent about properly marking the ECUs, but likely that's what it is.

Options:
You could buy the DP ECU, if there is one made for the S2R800, has to be a virgin unit.
Or, an aftermarket Ultimap/FIM U59, those are fully adjustable and very nice. Not a lot of folks around that can tune it.
The *proper* S2R800 ECU, but it has to be a virgin unit as well.
Maybe another option or two, but I think that's it.

Could you get the original ECU back from the guy who sold you the bike?

thanks.  what is a DP ECU? 

Sorry, it's a Ducati Performance ECU.  :)

oh, do you know how much they sell for?  would i need to go through the dealer?
thanks for your help.

I don't know how much they are, usually the 'kit' where they come with the cans is a good deal.

Check with your local dealer first for price and availability.

I unfortuntly know how much they are.
The ECU fried out on my m1000. The DP ECU alone was $1300.
I refused to be raped by Ducati like that so I opted for the U59 and mapper software.
So for less $$ I now have a fully mapabale ECU.

Lucky you. :( non OEM ECUs not good for Stepper motor bikes.
If you can go this route, i would do it in a heart beat. its like a DP ECU and PCIII in one. you loose your immbolizer though. and you can get whatever custom gauges you want, if you want. =D Plus its tuneable by almost anyone.

One check to see if you do have a mts1000 ecu will be to see at what rpm the limiter kicks in at. the 1000 (and 1100) motors are lower than the 800 motors.

I cannot remember the actual numbers but I bet you can get a few .... dozen DMF'rs to test theirs out for you. [clap]

You might see if you can sell the MTS ECU and put the proceeds of the sale towards a new, correct, ECU.

+1  He Man's right...more everyday, I'm starting to believe DP ECU is the only flawless way to go for the newer mills.
