Drive By Wire Advantages<\/span><\/p>\n

Please check your ECU features to see if it is capable of these functions.<\/span><\/p>\n

1-Very Fast:\u00a0 Generally capable of opening faster than cable or mechanical linkage setups.\u00a0 For example when a throttle blip is required for downshifts the ECU can command an instantaneous open throttle position (say directly to 25 percent throttle).\u00a0 If you were going to accomplish this with a cable setup the driver must move their foot from stationary position and sweep to the desired position. \u00a0This sweeping motion takes time.<\/span><\/p>\n

2-Cruise Control Function: \u00a0Drive By Wire offers the ability to target a drivers desired vehicle speed.<\/span><\/p>\n

3-Speed limit function: \u00a0Ability to override a driver\u2019s throttle command and limit maximum vehicle speed. \u00a0Helpful to avoid pit lane speed penalties.<\/span><\/p>\n

4-Traction Control: \u00a0\u00a0Controlled torque delivery by using the throttle position. \u00a0The ability to control torque delivery by gear to control wheel slip.<\/span><\/p>\n

5-Launch Control: \u00a0Able to have different ECU configurations for tire compound, track temperatures, wet or dry conditions, and other variables impacting traction.<\/span><\/p>\n

6-Blip Shifting: \u00a0ECU automatically opens throttles for rev matching downshifts.<\/span><\/p>\n

7-Throttle response curve can be manipulated to the driver’s liking:\u00a0 \u00a0This is often referred to as tip in. Some drivers like a snappy throttle and others prefer a more lethargic feel. For instance if first gear overpowers the car, it can be done such that torque is limited and finer torque resolution is achieved.\u00a0<\/span><\/p>\n

8-Idle Control: \u00a0Able to use the Drive By Wire actuator to automatically adjust and maintain a target idle speed even if engine load and conditions change (example: air conditioning turns on thus engine load increases).\u00a0 Can also be used in combination with ignition control to achieve a fine adjustment range.\u00a0<\/span><\/p>\n

9-Stall Recovery: \u00a0Able to use the ECU to automatically assist keeping the engine running by opening throttles if a stall condition occurs.<\/span><\/p>\n

10-Possibility of increased safety: There is no mechanical linkage between the pedal and the throttle system.\u00a0 This reduces the possibility of mechanical failures or binding.<\/span><\/p>\n

Both the pedal and throttle position sensors utilized in a drive by wire system should each have dual outputs (two separate sensors or a single sensor with dual outputs) for safety. \u00a0If the throttle position does not match the requested target, the ECU can immediately take corrective action.<\/span><\/p>\n

11-Calibration Aid:\u00a0 The ability to control throttle angle allows easy rpm sweeps (either dyno or in vehicle) at exact throttle positions allowing fueling or ignition mapping to be done much more efficiently.\u00a0<\/span><\/p>\n

12-Rev Limiter:\u00a0 The throttle can be used as an engine speed limiter with smoother action than cutting cylinders.\u00a0\u00a0<\/span><\/p>\n<\/div><\/div><\/div><\/div><\/div>
