How many vehicles does Protunes provide ECU and TCU files for?

Protunes provides ECU files and TCU files for 1828 vehicle models across 180 makes. The B2B file service covers petrol and diesel cars, 4WDs, utes, performance vehicles, motorcycles, marine and agricultural engines.

What power gain can I expect from an ECU tune?

Typical power gains range from 15-50 kW for Stage 1 tunes on stock hardware, 30-80 kW for Stage 2 with supporting modifications (intake, intercooler, exhaust), and 80+ kW for Stage 3 custom builds with upgraded turbo and fuelling. Each vehicle in the database shows its typical gain figure.

Are the gain figures measured at the wheels or at the engine?

The figures shown in the Vehicle Database are typical engine-level gain estimates aggregated from our calibration library — they represent expected improvements at the engine. For dyno-verified results measured at the wheels, hubs or flywheel — depending on the dyno type used — see the Tune Archive. Real-world delivered wheel/hub gains are typically 80-90% of the engine figure due to drivetrain loss.

How long has Protunes been in the ECU tuning industry?

Protunes brings 17+ years of professional ECU calibration experience to every file delivered. We've developed calibration files across petrol, diesel, performance, 4WD, motorcycle, marine and agricultural applications.

Who can purchase ECU files and TCU files from Protunes?

Protunes is a strictly B2B ECU and TCU file service. Tuning files are available exclusively to approved professional tuning workshops, performance workshops, ECU tuners, ECU calibrators, dyno tuners, flash tuners, chiptuners, diesel tuners, 4WD performance specialists, remote tuning professionals, race teams and independent automotive workshops across Australia. Files are not sold to retail customers. Workshop accounts can be applied for through the portal.
