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

Please follow this simple guide on how to check if Hondash will work with your ECU.

We encourage our customers to follow the compatibility guidelines prior to the item purchase, because of possible diagnostic connector differences between markets and model years. In case of US market, the compatible 3 pin connector was utilized only on OBD1 models ('92-'95), whereas the rest of the world (Europe, Japan, Australia, Russia, etc...) saw mixed usage of 3 pin / 5 pin on OBD1/2A/2B models ('91-'03).

Car models that use a 16 pin diagnostic connector version are not supported at this moment.

Yes, it does work, however the hardware and ROM setup must comply with the compatibility guidelines.

Yes you can. Communication with the ECU is not dependent on the profile. A profile only provides parameter definitions to increase accuracy of calculations e.g. fuel consumption, selected gear, engine revs etc. You can still create and customize your own profile based on one of the predefined profiles.

Connect the DLC connector to Hondash Scanner. The LED will start flashing. Open the Hondash app and follow instructions to pair Hondash scanner. Additionally you may configure custom car profile for more accurate readings.

DLC connector can be found in various locations under the dashboard.

Try to change the engine speed (revs) interpretation method in Settings → Car → Ecu.

Some OBD1 cars ('92-'95) don't have the power wire in the DLC connector (3 pin connector with only two wires, missing middle pin and wire). In this case you have to wire the scanner to a custom power source.

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 scanner to prevent possible car battery drain, when you power the scanner 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 scanner.

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
Fuel levelNo, the fuel level sending unit is not connected to the ECU

Please follow the guide on Fuel consumption calibration.

Currently no, but the app will receive an update to support it in later development stage. However this will not be a replacement for Hondash scanner as the ELM327 supports only newer vehicles.

The compatibility with OBD2 ISO 16 pin ECUs is being investigated, more information will be released in Q1 2020.

Android 4.0, Bluetooth 2.1, GPU graphics OpenGL ES 2.0

Yes you can, however we don't guarantee that it will 100% work. Very small percentage of models and manufacturers, usually the Chinese ones, have strict policies and allow only very specific devices to pair with their head units, or their Bluetooth communication implementation does not comply with the established Android SDK standards. Because our primary development platform is the smartphone we don't offer any assistance regarding head units (brands inquiry, etc.).

Hondash UID is a Unique Identification number of bluetooth scanner. 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 scanner and Hondash app with multiple devices at the same time, on any compatible vehicle. The number is sent via email on the day of order shipping.

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.
