Crank Position Sensor this sensor provides input signals to the ECM that indicate engine rpm how fast the engine is running in Revolutions Per Minute The ECM also uses these inputs to determine what stroke the engine is in so it can deliver the fuel and spark at the desired time Introduction 2 2 Manifold Absolute Pressure this sensor provides input signals to the ECM reacts to intake manifold pressure and ambient barometric pressure Intake manifold pressure reflects changes in engine speed and load Ambient barometric pressure reflects changes in atmospheric pressure caused by weather conditions or changes in altitude The ECM uses the inputs from this sensor to help calculate how much air is entering the engine IAT Intake Air Temperature this sensor provides input signals to the ECM as it reacts to the temperature of the air entering the engine For example hot air has less oxygen in it than cool air The ECM uses the inputs from this sensor to help calculate how much oxygen exists in a quantity of air ET Engine Temperature this sensor provides input signals to the ECM as it reacts to the engine temperature of the front cylinder head The ECM uses the signals from this sensor to determine if the engine is at operating temperature or warming up TP Throttle Position this sensor provides input signals to the ECM as it reacts to throttle shaft rotation telling the ECM throttle position if the thrott

Tuning with Advanced Tuning Mode Chassis Dynamometer amp AFR Meter This section is for those professional users who plan on testing the bike on a chassis dynamometer and measuring exhaust gases with an Air fuel meter This is the most efficient method of EFI tuning because the results of combustion can be accurately measured at the exhaust It does however require an in depth understanding of internal combustion engine theory dynamometer operation and AFR meter use Dyno testing a motorcycle is generally preferred over closed course track testing because it s quicker more efficient and safer if the operator follows the dyno manufacturer s instructions With a chassis dyno the tuner can measure view and compare the horsepower and torque of recorded runs and thereby know if their tuning adjustments have accomplished the ultimate goal of producing more power With the AFR meter the tuner can adjust the tuning tables to achieve the AFR desired for maximum power The combination of dyno testing and AFR measurement is particularly important when building high performance race engines with unknown combinations of performance accessories New engine configurations can offer the biggest tuning challenges and the tuner will find the AFR measurement invaluable Overview Tuning With a Chassis Dyno AFR Meter amp the Advanced Tuning Mode Inspect and prepare bike for testing Mount bike on dyno and connect AFR meter probes according to manufacturer s
