B2B ECU & TCU Tuning Files
Professional ECU Tuning
- Australia-wide, remote
- Stock file in, tuned file out
- Dyno-verified results
Recent results, from the dyno sheet
Every figure below is digitised from a dynamometer report supplied by the tuning workshop. Dyno type varies, so the numbers are measured at the wheels, hubs or flywheel depending on the equipment used.
What to expect
What it costs
Quoted per job, before any work starts. You upload the stock read and the vehicle details; you get a price in the portal and nothing is charged until you accept it.
How the file service worksHow long it takes
Enquiries are answered by email, usually within one business day. Turnaround on a file depends on the platform and what the job needs — the quote tells you before you commit, so the car is never on your hoist waiting on an unknown.
What a session needsIf it needs changing
Work runs in revisions, not in one shot. Each round is kept with the datalogs, dyno pulls and photographs that verify it, so a change is a next round on a documented job rather than starting again with a stranger.

From the workshop floor
Years of hands-on calibration in the workshop, 2015–2025, before the service moved to files and remote support. Protunes today is a file-only, remote calibration service — this is where its experience comes from, not how it runs now.

Frequently Asked Questions
Common questions about our B2B ECU & TCU file service.
Who can buy ECU and TCU tuning files from Protunes?
Protunes is a B2B file service for approved automotive businesses only — tuning workshops, dyno operators, flash tuners, chiptuners, and remote tuning professionals. Every account is manually reviewed and approved before access is granted. We do not sell to retail or private vehicle owners.
Which tuning platforms and tools do you support?
We provide custom ECU and TCU remap files across OEM platforms plus the major flash and standalone systems — including ECUtek, MHD, Bootmod3, HP Tuners, VersaTuner and PCMTec, and standalone ECUs such as Syvecs, Motec, Haltech, Link and Emtron. We cover petrol and diesel cars, 4WDs and utes, and performance applications.
How does the tuning file service work?
Approved workshops upload the vehicle's stock ECU read and select the make, model, ECU type and tuning options. We review the file and send a quote through the portal. Once the quote is accepted and paid, the file is hand-tuned to that specific vehicle — no generic maps — and delivered to your dashboard to download and flash.
Do you offer remote tuning?
Yes. Remote ECU calibration is available nationally for approved workshops and dealers across Australia, so you can receive professional tuned files without a physical dyno visit.
Where does Protunes operate?
Protunes is an Australian business and a national service. ECU and TCU files are delivered remotely through the dealer portal to approved tuning workshops in every state and territory, so you don't need to be local to work with us.
Are the tuned files road legal?
Files are supplied for off-road and motorsport / competition use only. It is the responsibility of the purchasing workshop to ensure any modifications comply with the regulations applicable to the vehicle's intended use.
Do you supply ECU and TCU tuning files Australia-wide?
Yes. Protunes is a national service — tuned ECU and TCU files are delivered remotely through the dealer portal to approved workshops in every Australian state and territory, with no in-person visit required.
Are your tuning files custom or generic off-the-shelf maps?
Every file is hand-tuned to the specific vehicle and its hardware — we do not supply generic, one-size-fits-all maps. The calibration is built around the stock read, the declared modifications and the intended application.
What do I need to provide to get a tuning file?
An approved workshop uploads the vehicle's original (stock) ECU or TCU read and selects the make, model and ECU type, then supplies a complete and accurate modification list — injectors, turbo, fuel system, intake, exhaust and intended use. Accurate hardware information is essential for a safe calibration.
Do you offer datalog review?
Yes. We review the data logs captured after a file is flashed — air-fuel ratio, boost, ignition timing, knock activity and injector duty cycle — and revise the calibration based on the logged data until it is confirmed stable.
Can you tune diesel 4WDs and utes?
Yes. We provide diesel ECU calibration files for common-rail platforms, including 4WD, ute, tow and performance applications, supplied for off-road and competition use.
Which vehicle makes and models do you support?
We provide ECU and TCU files for a wide range of petrol and diesel makes and models across the major manufacturers. You can browse the supported vehicles, with typical power gains for each platform, in the vehicle database, and see dyno-verified results in the tune archive.
