What we do

One partner for every software solution on the machine

Developed individually for engine, ECU and software version – never generic maps. Checksum corrected, dyno and field tested, backed by direct engineer support.

Stage 1 performance

Up to +30% power and torque with original hardware – safe limits for engine, transmission and drivetrain.

Eco / fuel economy

Up to –15% diesel for machines that live under partial load: transport, mowing, field work.

Emission solutions*

DPF, EGR and AdBlue/SCR software solutions with all related sensors and fault codes handled. Off-road and export use.

DTC, limiters & extras

Fault code logic, speed and RPM limiters, start-stop, hot-start fixes and combined packages.

* Emission-related solutions are intended for off-road, agricultural, export and motorsport use only, where permitted by local law.

Brands & machines

From the tractor to the excavator to the truck – we know the ECUs

Our database is deepest where others are thin: agricultural and construction machinery. Trucks, cars and marine engines are covered as well.

Why dealers work with us

Files from people who have stood next to the machine

We are not a file portal with a ticket queue. Every file is developed by engineers with 20+ years of workshop, motorsport and ECU experience – and you talk to them directly.

Direct engineer contact

Questions about a stubborn DTC or an unusual ECU? You reach the person who writes the file – by phone or e-mail, in English or German.

Real machine experience

From mechanic to technician to rally sport to ECU development: our files are tested on the dyno and in the field – towing, PTO load, long hours.

Works with your tool

No proprietary hardware. KESS3, K-TAG, New Genius, TheGenius, New Trasdata, Autotuner, CMD, Flex, bFlash, PCMflash – send the read, get the file back ready to flash.

How it works

1

Read the original

Read the ECU with your tool (OBD, bench or boot) and keep a backup.

2

Send machine details

Brand, model, engine, ECU, current software and the solution you need.

3

Flash & hand over

Your file comes back checksum-corrected, usually the same day. Flash, clear DTCs, test drive – done.

Who we are

20+ years from the workshop floor to ECU development

Byte Performance is run by engineers, not resellers. Our founder has been in the business since 2002 – starting as a mechanic, then technician, through rally sport into professional chiptuning at TuneLine Fahrzeugtechnik, Allcartuning and tuning24.org, before founding his own company in Graz, Austria.

Over two decades this has grown into one of the largest WinOLS project databases for agricultural and construction machinery – and a genuine passion for the hard part: reverse engineering ECU logic, developing DTC strategies and building deactivation solutions that work reliably in the field, not just on the bench.

Today Byte Performance is an independent tuning file brand for professional workshops and machinery dealers worldwide – with a dedicated dealer portal on the way.
