Tool comparison
SCT LiveLink (LiveLink Gen II) is the datalogging application in the SCT ecosystem. Connected through an SCT device such as the X4 or BDX, it records live PIDs and sensor data from the vehicle, then graphs, overlays, and analyzes the logs so tuners can validate and refine a calibration built in SCT Advantage. It supports OEM parameters plus external inputs, for example wideband air/fuel and EGT via analog inputs on supported devices, and lets users create custom gauge layouts and dashboards. LiveLink is used by both tuners and enthusiasts to monitor knock, fuel trims, boost, and air/fuel while road-testing Ford and GM vehicles. Logs are commonly emailed to a remote tuner for tune revisions in the SCT custom-tuning workflow.
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.
SCT LiveLink (Data Logging & Analysis, SCT Performance) 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.
