Bosch MS 6 - Throttle Calibration Procedure and Vehicle Test Setup

4 | Prepare Data Base
44/76 Engine_Control_Unit_MS_6.x_Manual Bosch Motorsport
Calibration:
CWTHRADJ Codeword for throttle adjust:
1 = automatical calibration process
2 = calibrate lower mechanical stop
3 = calibrate upper mechanical stop
4 = calibrate limp home position
Manual Procedure:
– Close throttle and set CWTHRADJ to 2.
– Open throttle fully and set CWTHRADJ to 3.
– Adjust the throttle to idle point.
– Do not forget to set CWTHRADJ back to 0. Check calibration by moving throttle.
4.4 Vehicle Test
Before starting with your vehicle test, some initial data should be set:
Speed & distance measurements The signals for speed calculation may be
available from different sources, like MS 6
own measurement, GPS data or via CAN re-
ceived information from ABS calculation. For
MS 6 own calculation, mechanical influ-
enced data like number of available sensors,
front wheel drive, number of detected incre-
ments, wheel circumferences and dynamic
corrections like corner speed application a
lot of functional options assist the calcula-
tion of the effective vehicle speed. Distance
measure channels may be derived from
speed information. For detailed information
see function description >CARSPEED<
CWWHEELCAN Selection for car speed from CAN signal
CWWHEEL Connected number of wheel speed sensors
or -signals
CWFWD Selection of front driven vehicle
CWSPEEDDYN Release of dynamic speed calculation
INC_FRONT Number of pulses per revolution of the
front speed signal
INC_REAR Number of pulses per revolution of the rear
speed signal
CIRCWHEEL_F Wheel circumference of the front wheels
Consider dynamic increase of the tire
CIRCWHEEL_R Wheel circumference of the rear wheels.
Consider dynamic increase of the tire.
Vwheel_xx Measure channel of the individual wheel
speeds
