If you want a good bang bang it 1s easier to have some monitored device for bringing in some air when the throttle is closing the motorised throttle or the proportional solenoid valve Bang bang quality is generated by three maps the motorised throttle or solenoid valve target map the injection map and the ignition advance map Refer to the Tuning RPM pressure map section for the description of injection and ignition map operation MOTORISED THROTTLE When using motorised throttle you have a target map showing the position of the throttle depending on the position of the pedal So you can manage the amount of air brought in at bang bang If you want to use the bang bang the map has to be wear a 0 load column The ECU will systematically look for the data in the 0 load column during the bang bang phase Normal working only starts with the next load column the ECU will never go to the 0 column in the normal mode Motorised throttle position target LINE SCALE COLUMN SCALE O E 100 200 F i 20 1000 10 1000 This map shows that the bang bang will open the throttle to the 200 value at 4 000 revs but normal lifted foot value at this point will be 10 TICK OVER SOLENOID VALVE With the proportional solenoid valve you have a target map that shows the position of the solenoid valve depending on the position of the throttle This permits to manage the amount of air brought in at bang bang If you want to

RPM has to be high enough and throttle opening or pedal in case of motorised throttle has to be light close to cut off in deceleration With RPM min for bang bang activation you don t activate the bang bang too low in revs you might not be able to control the vehicle any more The two last settings min pedal position and pedal hysteresis gives the opportunity to define when it is best to activate the bang bang depending on the position of the foot To get into the bang bang the pedal or throttle has to be below the limit in this particular case 100 To get out of the bang bang when re accelerating pedal or throttle position has to be higher than the limit plus hysteresis in this particular case 100 50 150 Never cancel hysteresis or you ll get into or out of the bang bang a lot of times and very fast when getting over the limit Don t forget the bang bang needs three conditions at the same time to be fulfilled a race configuration is required by the grounding earthing of pin 25 in the Challenger4 loom b max bang bang duration greater than 0 c one of the two auxiliary outputs 3 or 4 is configured in turbo management Page 45 55 Challenger 4 Tuning Pack In the bang bang mode injection cut off is systematically cancelled even if permitted by the software switch Cut off permission Injection cut off permission YES Cutting off is used if not in the bang bang mode Hil BANG BANG AIR SUPPLY

14. 0 millivolts the line input is never used in the conversion and so only one line is allowed for the conversion calculation the interpolation types are selectable STANDARD FAULTS STRATEGIES When a sensor input is seen as faulty by the Challenger le conversion value is simply replaced by a value which normally neutralises corresponding corrections to this sensor 1 Engine temperature takes the value 80 C 2 Intake temperature takes the value 20 C 3 Richness takes the value 1000 richness 1 4 Altim tric pressure in throttle RPM takes the value 1013 mbars 5 Intake pressure in vacuum RPM takes the maximum value allowed by the pressure sensor conversion map as if the sensor would deliver 5000 millivolts to give the maximum enrichment to the engine Page 50 55 Challenger 4 Tuning Pack ID SPECIFIC FAULT STRATEGIES TUNING A fault strategy can be implemented by adding a second line to the map on which the three first columns define the minimum tension below which the sensor is faulty the maximum tension above which the sensor is also faulty and the converted value to give in case of error The faults will appear when the user diagnostic is asked PRESSURE SENSORS This is an example of atmospheric pressure sensor conversion with a specific fault strategy tuning Atmospheric pressure sensor Pressure sensor analog input tension 0 Atmospheric pressure bars Absolute pressure conversio
