Stock ECU?

[michael holmes]

Hello,
After searching this forum and the www i'm still not clear about my ECU.
I got a new bike recently and i want to get to grips with it.
Its a 2004 620 monster capirex with ducati performance exhaust.

The ECU codes are -m620DUCATI027
                           -1211DG12
                           -45+-BD93E

I don't know if it's stock or some upgraded version, sometimes the DP exhaust came with
a modified ECU, it's not mentioned in the service papers of the bike.

Thanks for your time.

If I'm not mistaken they didn't sell slip ons with ECUs back then. The 2004 is EURO 2 (less lean) and more forgiving. Someone else might be sure. I'm better at my own bike and year(s).

Thanks,

On the airbox is a silver e3 sticker does that mean something?
When i checked the sparks they look a little white so i think the bike
is running a bit to lean, there's also a BMC airfiter used in my new bike.

At a constant speed with 3000-4000 rpm the bike is a litle raw like a
bit hesitating or stottering not to much but enough to notice it doesnt
run nice and smooth.

At higher rpm when pulling its runs just fine.

I just looked under the sticker with m620DUCATI027 there i found
another code that goes like this  
                                                61601.058.02
                                                MTS 1000
                                                DUCATI031

Could that mean multistrada 1000, i'm confused now that means it isnt stock but
an ecu from a 1000cc engine on a 620cc doesn't make any sense.
Or is it?

61601.058.02 seems to be a Magneti Marelli IAW5AMA0, but stock used to be 5.9M with the monster 620???

Happy easter, MH

I believe the only way you can tell if it is a Ducati Performance computer is have someone with the ability read the program.  If I remember correctly Ducati would just pull a computer, program it and put a sicker on it.  Another option is just have it tune for your bike.  I would choose the later from your symptoms.

ECU could be from many bikes and have been reflashed. Maybe it got the DP flash, maybe they disabled the immobilizer, maybe the previous ECU was faulty. Equally likely Ducati sold it with a different sticker, as many bikes over the years got weird stuff from leftover parts. Hard to tell with second-hand bikes unless you have paperwork or are told. A shop should be able to tell you what's on there (hopefully).

At a minimum, I'd have the TPS reset, throttle bodies synced, and air/fuel ratio adjusted.

[michael holmes]

Thanks for your replies.
So it can be altered many times in the last 14 year's.
Even from factory fitted with 1000mts ecu flashed to
620 monster ecu.

Al numbers or codes on the ecu are after all these years meaningless, very interresting.

Potentially. Just hard to know. Could have come that way from the factory, could have been messed with over the past decade. Only way to know for sure is getting it connected to some diagnostics and confirming.

I had one of the few Monster 620's that didn't have a clutch microswitch leading to some fun debugging when I got the ECU reflashed with a later model year map and it wanted the microswitch active to start.

The e3 sticker is probably euro 3 standard, it's an emission norm from 1999.

I don't think so, but could be mistaken ...

EURO 3 required catalytic converters, among other things. No Monsters pre S4R had them. Some of the S4R/S2R had the cat-ready udder, but it was empty (only in America?).

The E3 air box is pictured in my 2006 work shop manual. 2006. Proven EURO 2 bike. Leads me to think E3 is not meaning EURO 3. If I'm mistaken on that (too?) your bike might have a later model airbox.... which came as part of a larger upgrade job?

[thorn14]

I thought the early monsters had cat's in the slipons themselves.

[Speeddog]

There are DSS OEM cans with cats in them.

Transfer started with M900ie in '00, Across the board MXXXie in '02.

Carbs not a good combo with cats.

IIRC from a recent thread the e3 is an RF frequency interference spec that the bike meets.

I have the same bike, all the info online says 5.9 ecu but when I pulled the info out of my ecu it said 5am.  The monster & multistrada 1000 use a different hardware ecu than the other 5am bikes. You can not reset the TPS on them with out causing issues.  If you don't already have it download guzidiag & get a obd cable & fiat adapter. If you think you have the wrong ecu data, I can send you the ecu bin from my bike. If yours does have the 620 dp programming I would love to have a copy of it as it is very rare.

So, one correct and one wrong 

I checked the Ducati Performance catalog today - it doesn't show a DP ECU on any 620-900 exhaust, but plenty on S4 and S4R kits.

As far as I remember, way back when your 620 was new, you could either get exhaust or a kit including exhaust, DP computer and open air box lid with low restriction filter.  620 did not have cats.  More than likely, if you are not running an open airbox and you are running lean it is not a DP computer.  Someone suggested try a throttle synch and trim adjustment first.  I agree.  Oh, if the timing belts are over two years old, change them.
