3.3.2. Accurate calibration - achieving accuracy better than 1%
Accurate calibration is based on comparing real distance and fuel consumption values with values displayed on UTCOMP. You will calculate percentage
difference and make correction of constants. Start UTCOMP application, click "Help" and "Measurement Correction" tab.
In order to calibrate speed and distance
readings, you need to enter distance counted by
UTCOMP and real distance traveled by the
vehicle. Type also current VSS constant and click
"Calculate". Rewrite and save fixed VSS constant
to device settings. UTCOMP will recalculate
counted distance displayed in tacho screen.
In order to calibrate fuel consumption readings,
you need to enter average fuel consumption
counted by UTCOMP and real average fuel
consumption (you can calculate it using data
displayed on fuel distributor - measured on the
same distance). Type also current injection
constant and click "Calculate". Rewrite and save
fixed injection constant to device settings.
UTCOMP
will
recalculate
average
fuel
consumption displayed in tacho screen.
