Have you been curious if your new exhaust or intake really made more power? Tired of paying a mechanic to diagnose your check engine light? Want to know how your engine is really performing without spending a lot of money? Force is a vehicle performance and diagnostic tool that allows you to monitor all aspects of your vehicle’s engine. Unlike other applications, Force does not require an OBD-II Bluetooth module to measure torque and power. Force relies on your smartphones internal sensors and highly tuned digital filters to estimate torque and power without the need for external modules. If you would like to check engine diagnostic trouble codes (DTC’s) or log engine sensors, then Force will work with any OBD-II Bluetooth modules.
Without the need for an OBD-II Bluetooth module, Force's dynamometer (dyno) can accurately measure the torque, power and acceleration produced by a vehicle’s engine. In addition to torque and power, Force measures the ambient air temperature and atmospheric pressure which are two key factors in an engine’s performance. This allows you to compare different engine modifications (such as exhausts, intakes and ECU maps) with consideration for the ambient weather conditions that have a large effect on engine performance.
For those that want to know more about their engine, Force can be paired with any OBD-II Bluetooth module to provide information from key engine parameters (such as mass airflow, timing advance and intake manifold pressure) and the ability to check and clear diagnostic trouble codes/check engine lights (DTC’s/CEL’s). Force can log outputs from multiple engine sensors to an external .CSV file that can be opened in any spreadsheet application for further review. Force can read and clear both stored and pending diagnostic while also supporting over 2000 SAE diagnostic trouble code definitions. Most manufacture defined codes can also be read and cleared.
Far from a gimmick, Force is intended to be a serious performance tool providing results that are similar to expensive chassis dynamometers.
Force works in the same way as a chassis dynamometer (dyno) in that it measures the engines ability to accelerate an object. Where a chassis dynamometer measures the acceleration of a drum rotated by the vehicles wheels to calculate the torque and power, Force measures the vehicles acceleration on the road taking into account the vehicle weight, gearing and wind resistance to calculate torque and power. Force will generate torque and power measurements comparable to a chassis dynamometer (dyno).
Note that Force requires that your device is mounted in a vertical, level position somewhere in your vehicle (probably the windscreen). This means you will need a mount that can facilitate this.
Minor bug fixes to logger.
