Tool comparison
AEMpro is AEM Electronics' Windows data-analysis application, used to review and analyze logs recorded by AEM data loggers and dashes such as the AQ-1 logger and CD-series digital dashes. It lets users plot channels, overlay laps, build math channels, create custom charts and gauges, and correlate engine and vehicle data to support tuning and vehicle-setup decisions. Rather than writing calibrations, AEMpro focuses on turning recorded CAN and analog data into actionable insight, helping spot knock, lean spots, boost fluctuations, temperature trends and driver inputs across a run. It is commonly used alongside AEM's ECUs, wideband controllers and sensors to close the loop between logging hardware and tuning changes made in the ECU software, giving tuners an evidence-based view of each session.
Pi Toolbox is the professional data-analysis software originating with Pi Research and now offered under Cosworth. It is a long-established package in top-level motorsport — used across touring cars, GT, prototypes and single-seaters — for analysing telemetry from Pi/Cosworth loggers and ECUs. Users overlay multiple laps, build complex maths channels, create custom worksheets, and correlate driver inputs with vehicle dynamics and GPS track maps. Toolbox handles very high channel counts and sample rates, supports outing comparison and reporting, and is frequently the reference tool teams standardise on for post-session debriefs. It is an analysis and visualisation platform rather than a calibration tool, so it reads and interprets logged data instead of writing to the ECU.
AEMpro (Data Logging & Analysis, AEM Electronics) and Cosworth Pi Toolbox (Data Logging & Analysis, Cosworth) compete in the same space, so the choice comes down to coverage, workflow and price for your specific ECUs.
