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 secure remote access from any browser via tri-tune.com — plus a portable USB product.
Read and decode diagnostic trouble codes with a built-in searchable database — plain-English causes and fixes for every code.
Snapshot any gauge cluster, dyno chart, or log screenshot and let the built-in AI vision engine read and interpret it for you.
A curated directory of OEM service portals, subscription costs, and J2534 pass-thru device requirements by manufacturer.
Every customer tune is tracked as a job — from intake through data capture, baseline, review, and delivery, with artifacts attached.
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.
Tritune is in its beta phase — and that's an invitation. Bring your car, bike, boat, or bench project and help prove the platform on real hardware.
Got a Speeduino, MegaSquirt, or RusEFI project? A bike with a Power Commander? Beta testers get hands-on tuning support in exchange for real-world feedback and logs.
Join the BetaThe full Tritune workstation on a USB drive — drop it on any Windows machine, no install required. Beta testers get early builds first.
