I'll freely confess ignorance - but that doesn't mean I like doing it! :sneaky:

I'm looking for the ECM on my 2006 ST3 S so I can attach a Dobeck injection cheater on it and don't find a black box that looks to me like an ECM.

Is this it? I ask because what's pictured is nothing like what I find on line when I go looking for one to see what it should look like.

Whatever this is, is a Korean-manufactured item - and their corporate website does not show that they make products for Ducatis, at least not nowadays. 2006? Don't know.

The last owner of the bike had an aftermarket exhaust on it (Termis, I think) that he took off and gave away. I'm wondering if this should have gone with the pipes.

And if it's not the ECU, where would I find it?

Hmmm . . . further examination leads me to believe this is just the coil (Ihope) with a lead coming in to it from a tape-wrapped harness that disappears to nether regions where and ECM might be found. Where might that be?

The object in question is definitely a coil - and further exploration revealed another one, identical, at another location. Each coil has two high-tension leads, which led me to explore the wiring and engine further - which brought to light the fact that this engine is dual-plugged. Nowhere, in all the reading I've done, have I come across this crucial fact. Very interesting, and it helps explain how the engine manages to handle the high compression it generates.

But I still can't find the ECM! Aussie Bob, I looked down by the battery. There's a couple of gang plugs down there and a 40A fuse on the other end of it, but nothing that I recognize as the ECM.

The gang plugs are plugged into the ecu which should be bolted to the upright of the battery tray.

Sounds like you need to source some manuals.

Thank you, Ausie_Bob. You're right about further manuals, of course. I have LT Snyder's book, neatly trimmed of its binding and put into a 3-ring binder, but wasn't finding what I needed there. That schematic provides just what I was looking for.

Where's the emoji for, "dumbass?"

I have been searching for the ECM, (found it; thank you, Ausie-Bob) thinking that the Dobeck EJK connects to it. WRONG! That's an old guy memory at nonwork. (I used a Dobeck on a Harley 20+ years ago.) I had found the injectors and ID'ed the Dobeck connectors to them, but was baffled trying to find the ECM. I finally called Dobeck - they actually will talk to you, unlike some companies.

Anyway, my memory said the connectors on the Dobeck unit went to the ECM. Not so. They go in series to the O2 sensor cable; no connex at all to the ECM. I like Dobeck's product but their lack of instruction for those two leads assumes that the user is smart enough to figure out where they go; there is no mention of that in the installation instructions. I offer myself, a previous user, as proof that that is not a reasonable assumption.

However, I have it properly installed and the supplied map fixed the problems brought on the the stock Euro emissions map, coupled with the exhaust I opened up. Before Dobeck, the engine was erratically responsive and spat badly on decel throttle. Now it is adequately responsive to throttle and the backfire baby farts are gone. The system needs further tuning, which I can do; the tuning instructions are not great, but okay. Now, if I can just get enough fair weather up here in the Puget Sound area to so some tuning rides.
