Data

Data Capture

Mandated since 2001, European On-Board Diagnostics (EOBD) data varies from vehicle to vehicle depending on the manufacturer, make and model and also year of production, even though there is supposedly a common standard. In reality only the EOBD access point is common, but even these vary. The data recovery via the Airmax Remote system is only as good as the vehicle host systems, where even identical models may vary, therefore expectations must be modified and adjusted so that realistic service levels can be achieved. This doesn't mean that service delivery or data recovery issues can't be solved. Often all it takes to rectify or modify the system is access to an offending vehicle. Engineers then adjust or create a 'work around' to the software to ensure vehicle compatibility. There are rarely hardware issues. Airmax Remote currently achieves compatible software for 95% plus of poplar models with an ongoing development programme encompassing all new vehicle types.

A word of warning, the data that can be recovered is rich in content but still may vary in accuracy and availability. Recovered data is not altered but mirrored back to your PC as a web application. For example, mileage data is usually within 1% but this variation could be greater if the vehicle itself is inaccurate. The reports are designed to be as accurate, or for the purist, as inaccurate as the vehicle, to avoid confusion.

Post-report calibration can be added if the data reports are proven to be inaccurate. This often occurs when the vehicle’s own management system also allows a discrepancy by as much as 7%. In effect the engine's own data maybe accurate but the dashboard may display inaccuracies. Newer models are however improving. There is no legal requirement for vehicles to record accurate mileage.

If the system is fitted with optional GPS then mileage calculations can be verified or give you the choice of two figures.

For safety reasons the Airmax Remote RTU will not report with the first 500 metres of travel in case it's within a fuel station. Mini trips are not logged in their own right but are added to next journey exceeding 500 meters.

To help verify this Airmax Remote has completed a number of test track calibrations to compare received data against known and proven conditions using a ‘5th wheel’ and also GPS verification.
