Custom car profile

When the app launches for the first time, it loads default car profile. First step you need to do is creating a custom car profile for your car.






  • Navigate to "Settings" → "Car" and tap "Car profile manager"




  • Select one of the predefined base profiles, type in custom profile name and tap the button with the icon "plus"
  • You can create as many car profiles as you wish






  • Navigate to previous preference screen and activate your created profile to enable parameter editing

  • If there's no predefined car profile for your vehicle, you have to edit all necessary parameters to match your car specs. All engine and gearbox parameters can be found in service manual or you can simply google it.

    Engine

    In engine preference screen, edit the rev limit, red line start, injector count to match your car specs. The Fuel correction factor can be determined automatically via Fuel consumption calibration procedure.


  • Injector flow rate - (injector size [cc/min]) influences accuracy of fuel consumption calculations, define the exact injector size found in your engine

  • Fuel pressure values - same as above, however to find these parameters is not exactly an easy task, the only reliable source of information is the Honda service manual.
  • Guide on how to find the Fuel pressure values in the service manual:
    • download Honda service manual for your car model (use google)
    • find the section "Fuel System Supply" → "Fuel Pressure", in this example it's 11-118/119
    • there will be a section describing a fuel pressure testing procedure similar to this excerpt:

    • you'll find two ranges for fuel pressure, one at low engine load (vacuum hose connected), and one at high engine load (vacuum hose disconnected). In this example using B18C5, it's 260-310kPa for min fuel pressure, and 320-370kPa for max fuel pressure.
    • because the range is very wide we need to take average values, in this instance it would be 285kPa (2850mBar) for min fuel pressure and 345kPa (3450mBar) for max fuel pressure

    Gearbox

    In gearbox preference screen modify all gearbox parameters and wheel size accordingly. The VSS (Vehicle Speed Sensor) correction factor can be determined via Speed calibration tool, available in App toolbox.

  • D engine gearbox database:


  • ECU

    On ECU preference screen, select the appropriate interpretation method for engine revs and ignition advance calculations. Change the rev interpreting method only if you're getting strange readings, e.g. rev needle moving backwards etc. For the ignition advance interpretation, select a method that shows approx. 16 degrees at idle.

    Profile export

    You can submit a fully configured profile to developers so it can be added to the profile database. Only profiles for factory stock cars will be accepted.
