ANALOG #1 MODIFICATION (F3)

The SMT8-FT ANA1 feature can modify one analog signal, namely AIN and output the mapped signal on AOUT.

USAGE

 

An analog signal is a DC voltage generated from a number of different types of sensors; examples of these are the air flow meter, mass air flow meter (MAF) and pressure transducer (MAP) or temperature transducer.

 

 

ASSOCIATED PINS

 

AIN
Pin 4 of the 12-pin connector

AOUT
Pin 10 of the 12-pin connector

 

 

REQUIREMENTS

 

ANALOG #1 Lower Limit (Volts)
This voltage setting prohibits the analog output to go BELOW the limit.

 

ANALOG #1 High Limit (Volts)
This voltage setting prohibits the analog output to go ABOVE the limit

 

Set the analog zero offset compensation

 

 

MAIN (RPM/THROTTLE) MAP

 

For the RPM to work : Connect CRANK
For the Throttle (deflection) to work : Connect pin 11 of the 12-pin connector to the analog deflection signal (normally the throttle position sensor).
All map entries are in counts (without a decimal point) 100 counts entry equals 1.00 Volts.

 

 

COMPLETE CALCULATION

 

ANA1OUT =

ANA1IN
+- ANA1 MAP
+- AN1 ENGT

The ANA1OUT signal is limited to the lwo and high limits that are set in the Parameters Map (Shift F1)
