Hello to all of you fellow Ducati enthusiasts. My name is Daniel and I have been involved with Ducatis since about 2003. My passion and also my occupation is related to combustion engines with the focus on the electronics and controls, also known as engine management system. Since 2010 my company Deussen Engines served the European Ducati community with dyno tuning and ECU remapping. I have a lot of technical insight to all the Siemens/Continental/Vitesco (M3C, M3D, M4C, M4D) ECU's used by Ducati and can offer customization of my tunes to a very detailed level.

If anyone is in need of technical advice related to the engine ECU's, feel free to ask.

Cheers,

Daniel

Hello Daniel and welcome. I'm very interested in your profession.

Although I've never attempted to tune an engine properly I have done a lot of reading on the topic and taken have taken a course on it.

My question is regarding open loop O2 control and how optimally this strategy deals with variations in atmospheric conditions. I know it's not ideal and to be honest feels quite risky to me. So is it a risk to use this strategy on a bike that gets raced in mixed conditions throughout the year?

Closed loop O2 control is mainly there to keep the 3-way catalytic converter at the optimal conversion rate. The base fuelling is always corrected by ambient conditions (ambient pressure, intake air temperature and coolant temperature) so O2 control just does the fine tuning in the end. O2 control is typically limited to the rpm and load area of the emissions drive cycle. In racing conditions you will be outside this area for most of the time so the control loop will not effect the fuelling there. Does this answer your question?
 
Yes it certainly does... Thanks!

Am I correct in guessing that these bikes don't use a MAP or pressure sensor?

All current Ducati Models use MAP sensors for both manifold pressure measurement as well as ambient pressure adaptation.
 
That’s excellent!

A tune can be very all rounded with the correction parameters you mentioned if done thoroughly.

I’d like to mention that I read a lot of your Facebook posts and I’m interested in acquiring a tune by you in the future.

Do you have any experience with woolich? As far as I know they haven’t included shifter/ignition cut tuning to the V4 platform yet but does have a few benefits over the competition.

Thanks for you feedback.

Yes, I have a bit of experience with Woolich and I am using it for tuning and adding Blipper Systems to Yamahas. On the Ducati V4 side their knowledge is quite limited and a lot of the tables available in their software are not really what they name them. I know that quite a few shops work with it and I believe they pretty much just globally trim the fuelling.

All my Ducati tunes are always mapped cylinder individually with four wideband sensors. One ich in each header pipe. It is the only way to make sure all cylinders run balanced AFR and none of them gets damaged due to ruining to lean and und result too hot.

The shifter cut on the V4 is not a simple cut feature. It is actually a closed loop system based the the gear position sensor.

This confirms my preliminary thoughts on Woolich… I do like the file sharing aspect of that platform but I think I’ll hold off on them for now.

How about alien tech vs dimsport? Any real differences there aside from software interface? Do they differ in functionality for the end user of the tune?

Dimsport or Alientech are at the same level. I have ECU flashing tools from both companies. Both work fine and both companies provide very good support in case of issue. The handheld flasher I sell is from Dimsport. It is quite and old device and has been unchanged on the market for many years. But this is actually a good thing as the device software and hardware is very robust.
 
It’s good to know that you have experience with the various tools.

I’ll be glad to do business with you in the near future 😊

Perhaps a price list for your services would be of interest to many on this forum.

As I am not a forum sponsor or anything like that I do not want to create an advertisement with a price tag on here. Of course I am sure customer feedback and pricing information posted by other members are fine.
 
Where in the states can I eventually send a 1299 engine to get refreshed? I won't trust the dealer with setting bearing tolerances.
