Engine Control for Ducati superbikes

Replacement Ducati ECU - Nemesis-2 (updated Feb 2009) 

For 749 / 999 /  1098 / 848 Superbike, and now available for  Sport 1000 / GT 1000 / Hypermotard / 996R / 998 / Supersport DS and all Monster applications including S2R and S4R. See the downloads page for a list of currently available maps.

The original Nemesis has been replaced by the Nemesis-2 , and is still the worlds foremost 'plug in' replacement ECU for Ducati, offering unrivalled levels of user programmability. No more messy wiring alterations with 'piggy back' systems or putting up with emission controls that interfere with outright engine performance.

Nemesis-2 offers 'plug N play' replacement of the standard IAW5.9 ECU that is fitted to a great many Ducati motorcycles. We even offer a host of different maps to suit many different engine / exhaust combinations with many more under development. For those with a special project in mind of even if you want the ultimate map developing to suit your engine, every one of our Tuning Centre dealers are equipped with dyno facilities and lambda equipment to take advantage of the mapping capabilities.

You can even develop your own maps using the map editor software or by linking up your own wide band lambda equipment and taking to the track. Nemesis-2 is able to learn and correct itself for each cylinder.

If your still not sure about the Nemesis, here are a few comments from our dealers after their first taste of Nemesis

• The bike runs smooth and fuel consumption is lower now compared with Ducati Performance even if I have 9 hp more now. So hats off to you for making a good product. Just hoping you will make it for the whole Ducati range in the future… Patrik Holmberg - Biscaya Motor Racing AB (we now do)

• It's easy for me to sing the praises because the system works extremely well. - Doug Lofgren

• I was very happy, the Nemesis is working so beautifully . I love systems like this. - Ralf Mueller  - Be Faster

• Very good set up-thank you - Travis Schultze - Corse Superbikes

• We got a pole position. The Nemesis ecu is working very well for us. - Rudolf von Lignau - Ducati Miami

• I think you have a great product - Mark Sutton - Ducshop

• Thanks again for the support and wonderful product, the more parameters we have access to the more problems can be solved, it really is a fine product. - Fred Snyder - Silverback Performance 

Nemesis - Dictionary meaning

• An opponent that cannot be beaten or overcome.

• One that inflicts retribution or vengeance.

• A source of harm or ruin

• Greek Mythology : The goddess of retributive justice or vengeance.

Principal features :

• 100% compatible with the standard bike dash, all CAN communications are supported.

• Air pressure and air temperature received via CAN from the standard dash (type 1 ECU) or direct from a wired sensor (type 2 & 3 ECUs)

• Programmable quick shift input direct to the ECU

• Tilt switch input for race bikes

• All standard switch inputs for clutch, side stand, neutral supported

• Fan controls for overheat, same as standard (where fitted)

• 2 maps for race & road, toggled by pressing the start button after the engine is running – Dash will indicate the map change. (note: This function removes the possibility of triggering the lap time by pressing the starter button, this feature can be re-instated by fitting either a push button switch or an external infra red system to the existing bike connector) (not 996R or 998)

• Option to change tyre circumference

• 2 programmable shift lights (Superbikes & Hypermotard only)

• Programmable rev limiter, with dash warning to indicate ‘rev limiter activated’ (Superbikes & Hypermotard only)

• Fuel & spark advance correction against speed to adjust for air box pressure. (not 996R or 998)

• Closed loop fuelling correction to make mapping extremely quick, simply plug in and calibrate your external wide band lambda then define a ‘target’ AFR value, when ‘on-cell’ the ECU will self adjust.

• Stored diagnostics on inputs

• High speed 1mbps CAN link to an external logger.  

• Idle air valve control (where fitted)

Your Nemesis ECU is able to adjust all of the following parameters.

• Injector ‘dead time’ table (time to open the injector at differing battery voltages) This allows you to change injectors

• Coil dwell table for users who wish to change coils

• On/off selection for the ‘tilt switch’ input

• Full access to the throttle calibration and breakpoint selection

• RPM breakpoint selection

• Full access to the wide band lambda calibration and breakpoint selection (16 points)

• Pre-injection time – mSec of injector open duration at power on to prime the cylinders

• Fuel pump timer strategy

• Tilt switch strategy

• Over run fuel / spark strategy

• Temperature activation threshold for left and right cooling fan

• Professional ‘quick shift’ strategy

• Tyre circumference & trigger teeth calibration

• Rev limiters for spark and fuel (no limitations)

• Advanced transient strategy for fuel and spark advance with full user control

• Advance correction tables for air temp / water temp / horizontal and vertical cylinder / air pressure

• Injection correction for tables for air temp / water temp / air pressure

• Injection phase angle table plotted against RPM

• Horizontal cylinder injection table in mSec with 32 x RPM and 20 x Throttle breakpoints

• Vertical cylinder injection table in mSec with 32 x RPM and 20 x Throttle breakpoints

• Spark advance table in degrees with 32 x RPM and 20 x Throttle breakpoints

• Injection correction table as a function of speed with 32 x speed and 20 x Throttle breakpoints

• Advance correction table as a function of speed with 32 x speed and 20 x Throttle breakpoints

• Cranking correction (cold start map) with 32 x engine rotation and 20 x temperature breakpoints

• Your map may be loaded into map 1 or map 2 positions when you upload to the ECU, so the entire map may be different not just a trim.

• Target RPM value for cold start and normal running

Engine builder features:

• Accumulated mileage calculated from the speed input

• Total engine running minutes

• Total engine hours/minutes above 70% throttle

• Total engine hours/minutes above 9000rpm

• Maximum RPM

• Total number of times the engine exceeds your chosen speed limit

• Password locking of your maps within the ECU so that customers cannot see or make changes to your settings. They can however connect to the ECU to monitor any diagnostics.
