Tritune turns your real logged data and actual engine build into safe, data-backed fuel and ignition baselines — for cars, motorcycles, and marine applications.
Data-driven tuning you can trust — built around your specific build, not a generic guess.
Enter injectors, cams, compression, boost, and fuel — Tritune computes target AFR, ignition advance, VE, and max safe horsepower.
Import real logs and telemetry to calculate true volumetric efficiency with thermal correction and transient enrichment.
Full read/write for Speeduino, MegaSquirt, RusEFI (Proteus, microRusEFI, Hellen One, Frankenso) and FreeEMS.
Every map write is guarded. Dangerous values — lean AFR, over-advance, bad data — are blocked with a clear reason.
Generate Power Commander and Bazzaz fuel maps, Speeduino/MegaSquirt tables, and piggyback CSVs.
Desktop workstation, mobile dashboard, and a portable USB product that drops onto any machine.
From build to baseline in four simple steps.
Tell Tritune your engine — injectors, cams, compression, boost, fuel type, ignition. The more detail, the better the baseline.
Import real logs or connect read-only telemetry (ELM327/OBD-II, HP Tuners, CSV). Tritune calculates true volumetric efficiency.
See your target AFR, ignition advance, VE, and safe horsepower — safety-gated so nothing dangerous can reach your engine.
Generate Power Commander/Bazzaz maps or Speeduino/MegaSquirt tables and stage them — bench-validated before any vehicle write.
Honest capability mapping across cars, motorcycles, and marine — no over-promising.
