CHIP TUNING VARI-SIGNAL DPF SIM INSTRUCTIONS
REQUIRED FOR SOFTWARE:
- HIGH END SCAN TOOL THAT READS LIVE DATA ON THE VEHICLE IN QUESTION
- WINDOWS COMPUTER
To open, double click the Utility Program that accompanied your DPF Simulator (Sim) or download the software from this link: https://chiptuning.com.au/dpf-simulator-utility/
You will need to unzip the program first.
The DPF Sim you have ordered comes pre-set for most international versions of the vehicle in question however, it may be that your specific vehicle may need some tweaking of the sensor values to make the vehicle’s ECU happy.
The DPF Sim Software is used to increase or decrease values to correctly fool the vehicle’s ECU. Connection of the Sim to the vehicle’s Fuel Rail Sensor will regulate the performance of the Sim whilst under load to provide the variation of signal needed. That part is fully automated.
Ch 1-4 Settings on the Program represents the DPF Temp Sensors on your vehicle. If your vehicle has 2 or 3 DPF Temp Sensors, just leave the remaining Temp Sensor wires from Sim UN-USED (tied or cut back) and insulated.
To make it easier provide tech support, if you have only 2 DPF Temp Sensors, use the Red wire for the front DPF Temp Sensor, the Blue for the rear. ie: Slider No 3 and 4.
TEMP SENSORS: You can adjust the readings of the DPF Temp Sensors hotter or colder by sliding the corresponding coloured slider down or up or by entering values directly under the slider. Typically Down = hotter | Up = cooler. 2x Black wires correspond to 2x Black sliders and so forth.
Check with a Scan Tool that the values at the DPF Temp Sensors are between 700 – 760 Degrees Cel. As you use the corresponding slider you will see the values on the scan tool vary. Adjust, if necessary to read low to mid 700s for ALL DPF sensors. NB: DPF Sensor is NOT a Catalytic or Engine Temp Sensor.
PRESSURE DIFFERENTIAL SENSOR: The Box located at the bottom right hand side of the screen (GROUP BOX) is the Pressure Differential Pressure Sensor (DPS) voltage reference.
Default setting is at 1.2volts. Typically: Slide up, to increase Voltage, Slide down to decrease Voltage.
You need the value on the Scan Tool to read approx. as follows:
@ Idle 0kPa
@ 2000 RPM 2kPa
@ 2600 RPM 4kPa
The Drop Down box will allow the slider to operate after a certain voltage as sensed on the Fuel Sensor Signal Wire between the listed voltage ranges.
If > 1.0v (greater than X) the Sim will give no voltage output until the Sim receives a signal from fuel rail sensor of OVER 1volt. @ 1v the PDS output will commence. Typically leave this at the pre-set value.
Under 1 volt, the output is zero. Zero means Sim will output a SET value without any fluctuating voltages which would normally be the case.
IF > 1.5 it means there will be no voltage output until it receives signal from rail of OVER 1.5v.
@ 1.5v the PDS output will commence.
Same with 2.0, 2.5 and 3.0
