What we build

Every file below is custom-made on your original read — software only, no hardware changes. Pricing lives on the Pricing page — here, request exactly what you need.

Stage 1 performance

Petrol & diesel. A reworked file that unlocks more torque, throttle response and power — dyno-validated, no hardware changes.

TCU / gearbox tuning

DSG, ZF, PDK, Powershift, Tiptronic. A gearbox file with faster shifts and higher torque limits, calibrated per transmission.

E85 / FlexFuel

Ethanol compatibility for petrol engines — ignition and injection recalibrated in the file for E85.

Pop & bang / crackle

Overrun pops and crackle on deceleration. Off-road / track use, petrol engines.

Launch control

Optimized RPM hold for consistent, repeatable performance starts where supported.

No-lift shift & hard cut

Full-throttle upshifts and aggressive rev-cut for faster gear changes.

Exhaust flap control

Keep the exhaust valve open for a fuller sound, independent of drive mode.

Limiter adjustments

Speed limiter (Vmax) and rev-limiter adjustments for motorsport applications.

We perfect Stage 1 — we don't chase Stage 2/3

Stage 2/3 need hardware changes and dyno calibration on the car. We deliberately stay where we're excellent: safe, reliable, software-only files for factory hardware — calibrated by hand, never auto-generated.

Tools & expertise

We work with the full professional toolchain — bench, boot, OBD and BDM — across all major ECU families.

ECU coverage: Bosch (EDC16/17, MED17, MG1, MD1) · Continental (SID, Simos, PCR) · Delphi · Magneti Marelli · Denso · Siemens · Keihin · Visteon

Performance work, the way it should be done

Custom engine and gearbox files, hand-built on your original read and checksum-verified before delivery — software only, no hardware changes.

Stage 1 done right

Software only

A reworked file that unlocks the torque and power your engine already has — no hardware changes, dyno-validated, usable every day.

Gearbox & TCU

DSG · ZF · PDK

A gearbox file with faster shifts and higher torque limits, calibrated per transmission — never a generic copy-paste.

Motorsport extras

Track & off-road

Pop & bang, launch control, no-lift shift, exhaust flap and limiter work — added cleanly on request.

Built for your car

Send your file

Send your original read with the model year, engine and gearbox type. Every map is matched to your exact ECU and hand-tuned by an engineer.

Off-road / track use only where applicable. Compliance with local regulations is the buyer's responsibility.

GTBackup Stage 1 files — custom ECU remapping, hand-written by engineers, checksum-verified, fully reversible.

More torque & power

Stage 1 remap
A custom Stage 1 ECU file unlocks stronger mid-range torque and horsepower on turbocharged petrol and diesel engines — dyno-validated, no hardware changes.

Sharper response

Throttle & boost
Optimized fuel mapping, ignition timing and boost control remove flat spots for instant, linear throttle response.

Better economy

Everyday & fleets
More efficient combustion means the engine works less at cruising speed — many drivers and fleets see lower fuel consumption after a remap.

Safe & reversible

Original kept
Hand-calibrated within safe limits and checksum-verified, with your original ECU file (ORI) always included so every change is reversible.
Every Stage 1 file is hand-written from your original read, checksum-corrected and test-checked before delivery — never a generic database dump.
GTBackup performance build standard
Our build standard
On every performance file
Your original ECU file is always included, so any change is fully reversible — and gearbox (TCU) tuning is available to match the extra torque.
