Tool comparison
VCM Scanner is the datalogging and diagnostics component of HP Tuners' VCM Suite. Connected through an MPVI2/MPVI3 interface, it streams live OEM parameters and wideband inputs, records channels for tune validation, graphs and overlays logs, and reads and clears diagnostic trouble codes. Tuners use it to watch knock retard, fuel trims, boost, air/fuel ratio, and transmission behavior while dialing in a calibration edited in VCM Editor. It supports high-speed CAN logging and custom math channels, and can integrate external inputs such as EGT and wideband controllers. VCM Scanner is standard equipment in North American performance shops working on GM, Ford, and Dodge platforms, and is often left connected during dyno pulls and road tuning to capture data for revisions.
Cosworth Toolbox is the data-analysis environment used with Cosworth Electronics data loggers, dashes and motorsport ECUs. Engineers import logged channels — engine RPM, throttle, wheel speeds, GPS, suspension, temperatures — overlay laps, build maths channels, and study driver and vehicle behaviour against track position. It descends from the Pi Research toolchain and is common in circuit racing, rallying and single-seater categories where Cosworth hardware records at high sample rates. The software focuses on post-session and near-live telemetry review rather than ECU calibration, giving race engineers the plots, histograms and reports needed to make setup and strategy decisions. It pairs with Cosworth logging hardware over CAN and Ethernet, reading and interpreting recorded data rather than writing to the engine ECU.
HP Tuners VCM Scanner (Data Logging & Analysis, HP Tuners) and Cosworth Toolbox (Data Logging & Analysis, Cosworth) compete in the same space, so the choice comes down to coverage, workflow and price for your specific ECUs.
