DIGITAL ECU TUNER 3 – User Manual
MAF (0-5V) to MAP conversion
To make the conversion, connect MAF sensor to one of the analog inputs of DET 3.As a load connect map sensor.
In the example bellow, the MAF sensor is connected to the Analog input #1 and the MAP sensor to the
Analog input #4
Configuration of the fuel table and analog output at this stage should look as follows:
Next, choose the Log tab, press the Clear button (to reset the previous log) and then take a ride. The data gathered
during the ride will be used to generate the conversion table, so it is very important to drive with diverse load and
RPM). After the stage of data gathering, on the log window press the right mouse button and choose Convert MAF
to MAP option. Fuel table will be created, which has to be saved in the devices memory (MAKE MAPS
PERMANENT). It is also important to change settings in the tables and analog output configurations (set the
Analog out offset value to 2.490V and the value of Modified to ZERO).
Warning!
During data gathering engine should have the working temperature.
