FAQ


All Honda models (1992-2001 - gasoline engines - OBD1/2A/2B) that use the proprietary 3 pin or 5 pin DLC diagnostics connector are fully compatible and supported.


Yes, it does work with some of them, for more details on this topic please read the post Aftermarket / chipped ECU.

Yes you can, the profiles do not affect the functionality of communication with the ECU, they only provide values to increase accuracy of calculations for fuel consumption, selected gear, engine revs etc. You can edit the available profiles to make your own custom profile.

You can find the information here.

You can read about features of Hondash here.

Connect the DLC connector to Hondash Interface. The LED will start flashing. Open the Hondash app and follow instructions to pair Hondash interface. More information on pairing here. Additionally you may configure custom car profile for more accurate readings, more info here.

DLC connector can be found in various locations described here.

Try to change the rev interpretation method in Settings → Car → Ecu. There are 3 possible methods to calculate engine rev value, depending on the car's Ecu, usually OBD2A method 0, OBD1 method 1 (e.g. Ecu P28 requires method 1 to display engine rpm correctly).

Some OBD1 cars ('92-'95) don't have the power wire in the DLC connector. In this case you have to wire the interface as described here.

No, you can leave it connected. However if you're not going to drive for a longer period it's highly recommended to disconnect the interface to prevent possible car battery drain, when you power the interface directly from DLC port, which is hot at all times.
For permanent installation it's recommended to use an ignition switched power source to power up the interface.

Oil TemperatureNo, Honda engine does not have an oil temperature sensor
Oil PressureNo, Honda engine does not have an oil pressure sensor, only a pressure switch
AFR - Air to Fuel RatioNo, the majority of Honda engines use a narrow band oxygen sensor which can't read AFR values, the minority that can read AFR, is not supported currently
Fuel levelNo, the fuel level sending unit is not connected to the ECU

Please follow this guide on Fuel consumption calibration.

Currently no, but the app will receive an update to support it in Q1 2019.

Compatibility with standard ISO 16 pin OBD2 ECUs will be incorporated using ELM327 interface in Q1 2019.

Android 4.0, Bluetooth 2.1, GPU graphics OpenGL ES 2.0

Hondash UID is a Unique Identification number of bluetooth interface. One of the purposes of this number is to identify the Hondash in device list thus avoiding using other devices with identical name. It doesn't restrict the user in any way. You can use your Hondash bluetooth interface and Hondash app with multiple devices at the same time, on any compatible vehicle.

No, however the support is being considered. No further details available at this moment.
Since Hondash works with Android versions as old as 4.0 (2011) we suggest to buy a cheap used device (~€30) to work around this issue and use it as a dedicated device for Hondash.
