Car profile

When the app launches for the first time, it loads default car profile. First step you need to do is to navigate to app / car settings and choose a car profile from the profile list in order to increase overal accuracy of calculations and gain access to all features of the app.

If there's no pre-defined car profile for your car, choose one that closely matches and proceed with adjusting and editing the parameters to get it right. Service manual or google are your best friends in this case.

Engine

In category "engine", 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, after finishing the profile configuration.

  • Fuel pressure values - influence accuracy of fuel consumption calculations, you can find these parameters in Honda 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:
    hondash app car engine fuel pressures in manual

    • 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 - 310 kPa (average value 285 kPa = 2850 mBar) for min fuel pressure, and 320 - 370 kPa (average value 345 kPa = 3450 mBar) for max fuel pressure.

  • Gearbox

    In category "gearbox", modify all gearbox parameters accordingly. The VSS (Vehicle Speed Sensor) correction factor can be determined using the Speed calibration tool, available in App toolbox, after finishing the profile configuration.

  • D engine gear ratios list (use google or service manual for other engines):

  • hondash app D series gearbox ratios


    Wheels

    In category "Wheels", modify the parameters to match your wheel and tire specs on the drive axle.

    ECU

    In category "Ecu", select the appropriate interpretation method for engine speed (revs) and ignition advance.
    hondash app ecu settings

  • Engine speed (Revs) interpretation method:
    select the method that calculates approx. 800 ± 50 [rpm] at idle, in case you're getting strange readings such as needle pointer moving backwards, etc.
    There are 3 possible methods to calculate the engine speed (revs) value. Depending on the car's Ecu, usually OBD2A requires method 0, OBD1 method 1 (e.g. Ecu P28 requires method 1 to display engine speed correctly).

  • Ignition advance interpretation method:
    select the method that calculates approx. 16 ± 2 [°] 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.
