Link g4x fuel pressure data not show on realdash

Hi Realdash,

Im having a problem regarding on fuel pressure reading in realdash (android).
On realdash everything is running fine. Just that my Fuel pressure not running.

  • On my LINK ECU side i had double confirm that my fuel pressure its running accurately
  • I had tried select the UNITS & VALUES\INPUT MAPPING to Fuel Pressure its not working
  • I had tried change the UNITS & VALUES\INPUT MAPPING to Link ECU: Fuel Pressure Its same not working
  • I had try ADD NEW INPUT MAPPING at Setting area Fuel Pressure is set from OIL PRESURE (SIMULATED) same its not working
  • I had try ADD NEW INPUT MAPPING at Setting area Link ECU: Fuel Pressure is set from OIL PRESURE (SIMULATED) come out the data its not correct [ Even i on ignition the reading shown 0 that meant its not reading correctly]

All other function is running fine ( OIL PRESS / OIL TEMP / LAMBDA / RPM / WATER TEMP & ETC ) Just that the fuel pressure no mather how i calibrate its not running correctly

  • I had check its not wiring connection issue
  • sensor its running fine due to PCLink is reading actual fuel pressure reading

Can help me above problem?

First, with engine running go to ‘Settings->Application->Debug->Debug Data View’

This view will show every input that is updated in RealDash. See Custom values if you can see actual/real fuel pressure value.

will try it tmr to get the realtime value. thx


Hi Dev,

I checked with the Debug data view - Fuel Pressure got 0 Reading (but on link g4x PClink side fuel pressure is running normal)

In same view, select ‘Custom’ category to see ECU specific values. Is there any analog input value that corresponds to your fuel pressure?


there is no fuel pressure input on custom

It seems like your setup does not send fuel pressure or Analog inputs to RealDash. I’m not an expert on Link ECU configuration so cannot help much on how to configure it.

Are you connected to ECU with CAN adapter?

yes i connect ecu with Can Adapter

On Link DASH2PRO file, there clearly is a CAN frame for the Fuel Pressure. Why your ECU is not sending the value, I do not know. You probably have to check/configure your ECU CAN output with their PCLink software.
