Field notes
The practice flow separates learning, simulation, and investigation: learners can study channels and fundamentals, test changes against synthetic material, then map channels from an exported CSV. The sample uses illustrative combined short- and long-term fuel-trim corrections, and the site cautions that available channels affect what can be evaluated. It lists limited coverage for diesel, direct-injection, boosted, and unknown vehicle profiles.
