DTC COMMUNICATION It’ss not enough to just say “…and It and the bike has Ducati Traction Control... Control ” Understanding 2009 Ducati Traction Control… XXXX …what what the system is is. …how it works. …the benefits. This incredible piece of electronic genius sets new standards in sport bike performance and safety and represents an important ‘feature’ for Ducati range. Our constant sport bike quest for more power and less weight now runs parallel with an ongoing program to enhance control and safety. DTC is a highly intelligent system that acts as a ‘filter’ between the rider’s right hand and the rear tyre. In milliseconds, DTC is able detect and subsequently control wheel-spin, considerably reducing the risk of incident. However, DTC is intended as a ‘rider aid’ and does not remove the risk of incident. Use this document to learn about the system and take some time to navigate your way through a DTC display. display

DTC CONTINUOUS DEVELOPMENT
Since its early 2008 introduction on the 1098 R, when the system could onlyy be used on the track,, Ducati Traction Control (DTC) ( ) has undergone continuous development to make it suitable for the road. This has been achieved on the 2009 1098 R Bayliss, 1198 S and the Streetfighter g S,, byy controlling g wheel-spin p with a combination of ignition retardation and a pattern of fuel injection cuts. The 2008 system y cut the ignition g spark p and therefore,, released unburnt fuel into the exhaust system which would have compromised the efficiency of a catalyser if fitted. For this reason the 2008 system y could only y be used with non-catalysed race mufflers which restricted the system to track use only. g the case. From 2009 this is no longer

DTC WHEEL SPEEDS
When the profile that best suits the combination of road or track conditions and riding style has been selected and the DTC system activated, activated front and rear wheel sensors compare speed differential to sense the amount of wheel-spin.
DTC ECU
If the system recognises wheel-spin wheel spin above a certain threshold, the DTC ECU administers two types of interaction in varying amounts, amounts calculated with values supplied from multiple channels of data.

DTC STAGE 1 INTERACTION The first ‘soft’ stage of system interaction is executed by high speed software that instantly makes electronic adjustment to the ignition timing by administering varying amounts of ignition retardation to reduce the engine’s torque output. DTC ECU Ignition spark retardation

DTC DATA CHANNELS With so many possible wheel-spin scenarios, DTC calculates instant data sent from multiple sources before deciding how best to interact with the power delivery. From slow mid-corner acceleration with considerable vehicle inclination to high speed corner exits while almost upright, DTC instantly processes a mass of data input to react according to the motorcycle’s exact ‘dynamic situation’.

DTC FULL POWER Smooth and carefully programmed return to full power After either Stage 1 (ignition retardation) and/or stage 2 (pattern of injection cuts or full cut), the system will incrementally return to the original ignition and/or injection mapping as the wheel speeds approach equalisation. As traction control is required during extreme riding situations, this smooth and carefully programmed p og a ed return etu to full u power delivery is the key to efficient operation and a ‘fluid’ riding style.

DTC INNOVATIVE THINKING There is Th i a generall misconception i ti about b t wheel h l speeds d when h cornering on different rolling-diameters of tyre section. This has no effect on DTC when comparing wheel speeds. The most important data is the differential in f t and front d rear wheel h l speeds d and d this thi data d t is i ‘re-sampled’ every 10 milliseconds to establish the system base-line. The reall innovative Th i ti thi thinking ki b behind hi d DTC iis how the range of sensitivity levels decide exactly how to react to excessive wheel-spin by understanding the bik ’ ‘dynamic bike’s ‘d i situation’. it ti ’ This ‘system intelligence' is achieved by processing a mass off d data t iin a matter tt off jjustt milliseconds, and it exists thanks to the thousands of laps and hours spent testing, programming i and d earning i race victories.

DTC DATA ACQUISITION Recording the amount of DTC intervention For 2009, an additional channel of information has been added to the Ducati Data Analysis system, dedicated to recording the DTC index (a value that quantifies the amount of traction control used during a data recording session) session). DDA is supplied as standard equipment on the, 1098 R Bayliss, 1198 S and Streetfighter S. Once downloaded a graphic trace can be viewed to reveal just how much DTC interaction has been used to reduce wheel-spin. When viewed alongside channels of data recording throttle opening, vehicle speed, engine rpm and distance travelled or laps and lap times the system provides a times, valuable and fascinating analysis of the performance of both bike and rider when using DTC.

DTC Q&A – SAFETY Is it impossible to lose rear wheel traction with DTC activated? No! Although one of the clear benefits of DTC is increased safety, the system should be regarded first and foremost as a ‘rider aid’ that improves performance and great care should always be taken not to exceed obvious limits limits. Poor motorcycle preparation, incorrect set-up, tyre condition, poor road or track surface or simply ‘excessive cornering speed’ can all potentially contribute to uncontrollable loss of rear wheel traction - even with DTC activated. activated

DTC Q&A – CHANGING DTC LEVEL IN MOTION Is it possible to change DTC level while riding? NO. Both the initial activation of the system and the selection or change of DTC level can only be done when the motorcycle is stationary. While there are obvious benefits in being able to change DTC level while riding, riding there are also a number of safety considerations that have been factored into the design. Firstly, and most obviously, ‘due care and attention’ to other road or track users would be seriouslyy compromised if the rider was navigating the set-up menus and selecting a DTC level while riding. Secondly, adjusting the DTC level in the wrong direction during a road or track session because the rider’s attention is reduced, risks the DTC system being less sensitive than expected. For these reasons, it is important that the rider leaves the road or track and parks the motorcycle before entering the system set-up and calmly deciding which level best suits their riding style and/or environment.

DTC Q&A – CHANGING ORIGINAL GEARING Does changing the original final drive gearing effect DTC? NO. There is no part of the DTC system effected by the final drive gearing.

24
DTC Q&A – STREET TYRES Is it ok to change from the original equipment tyres? NO. The 8 levels of sensitivity offered by the DTC system operate in a range dictated by the diameter, profile and rolling-circumference of the the original equipment tyres. tyres Changing the type of tyre for street use could seriously effect the performance of DTC and so must be avoided and discouraged. .
DUCATI TRACTION CONTROL
25
DTC Q&A – TRACK TYRES Is it ok to change from the original equipment tyres for the track? YES BUT... Consider that if you change tyre type, it is highly likely that only DTC levels 1-3 (intended for highly competent track riders) will function within the software's pre-set margins. The remaining levels are likely to be outside of the calculation tolerances.
DUCATI TRACTION CONTROL
26
DTC Q&A – TRACK BODYWORK When changing bodywork can the DTC ECU be repositioned anywhere? NO. If after-market bodywork is fitted, it is vitally important that the DTC ECU, located in the tail fairing, is positioned (and angled) exactly as it is in the original bodywork. Failure to do so, will seriously effect the performance of the DTC system.
DUCATI TRACTION CONTROL
27
DTC Q&A – SOFTWARE DIFFERENCES Are all 8 DTC levels the same for the 1098 R Bayliss and 1198 S? YES. For 2009, all three models share the same software and intervention profile programming because they have similar power outputs, outputs transmissions and chassis configurations.
DUCATI TRACTION CONTROL
28
DTC Q&A – WHEELIES Is it still possible to ‘wheelie’ wheelie with DTC activated? YES. As DTC’s intelligent ECU reads all data channels to understand the motorcycle’s exact ‘dynamic situation’, electronic considerations are made to distinguish front and rear wheel speed differential during ‘wheelies’ and so avoid system intervention.
DUCATI TRACTION CONTROL
29
DTC Q&A – BURNOUTS Is it still possible to do a ‘burnout’ burnout with DTC activated? YES. DTC does not activate at (front wheel) speeds less than 30km/h (19mph) for the 1098 R and 20km/h (12mph) for the 1198 S, so burnouts performed below these speeds are permitted by the system system.
