APR is pleased to present APR Mobile! APR Mobile is a simple yet powerful tool designed to enhance the APR tuning experience. APR Mobile installs on smart phones, tablets and other devices and provides a wireless connection to the vehicle’s engine control unit or ECU. Once connected, the device can be used to access APR’s EMCS program switching features, read and clear fault codes and data log the ECU at high data rates not found on other commercially available tools. The app can also be used to access APR’s latest news articles, locate dealers in APR’s network and review previously saved data logging sessions.

With direct access to the ECU, APR Mobile has the ability to support and interact with any functionality APR codes into the OEM ECU. That which is available today is only the beginning!

Should the need ever arise, where available APR’s existing EMCS program switching features still remain conveniently accessible through the OEM cruise control stalk.

APR Mobile Explorer Data logging Suite

High speed datalogging!

Data logging has proven to be an essential tool in vehicle diagnosis and learning the inner workings of the engine, but commercially available tools are slow and painfully limited. APR’s Mobile ECU Explorer has complete access to the inner workings of the ECU, similar to those available to APR’s calibration experts and OEM engineers alike.


APR Mobile Explorer is capable of wirelessly logging enough variables at once to get a complete overview of the engines current operating state and does so at sample rates fast enough for detailed analysis. For each supported ECU and engine type, APR’s engineers hand select operating values, which they feel are beneficial for your diagnosis needs. Should the need arise for access to more variables on new platforms, APR’s engineers can instantly push more variables to the phone without requiring the user to update the application.

APR Mobile Explorer can graph multiple items in real time and allow the end user to stop and recall the logging sessions to precisely read individual values in greater detail. Each log is automatically saved and can be emailed in a convenient .csv format for later analysis on desktop computers.

APR Fault Code Diagnostic Center

APR’s fault code erase makes diagnos quick and simple. Should the vehicle ever throw a check engine light or fault code, the application will alert the end user with information related to the code. In many cases the code is related to something simple, such as an unplugged sensor, or loose gas cap. In such case, end user diagnosis and repair is simple, potentially prevent a costly and time-consuming trip to the dealership or repair shop. With a simple click of a button, fault codes can be cleared.
