DIGITAL ECU TUNER 3 – User Manual
Corrections on the map should be made if needed (special attention should be paid to the idle revolution).
Additionally, using the air temperature sensor in the intake manifold, it is possible to make correction of the fuel
dose, depending on the intake air temperature ( lower the fuel dose when the temperature of the intake air rises).
Caution !
In some cars, ECU checks the value of the signal from the flow meter just after the
car’s start. DET 3 needs about 6ms for initialization. During this time, on the analog
output, there is the value from the analog input. In our case, it will be 0V. To avoid the
ECU limp mode, in the device’s configuration
Force Startup Output Value
option
should be set
,
and later, in the
Startup Value
set the MAF sensor voltage of non
running engine.
