ECU Calibration & Development

Real calibration.
Not a canned file.

Remote tuning files over the internet — no ECU shipping required — plus custom operating systems and bench work for performance shops and owners who want the job done properly. Every file is written against your actual read — checksum-corrected, byte-verified, and backed by free revisions for the first year — re-tunes at 50% if nothing major changed.

E90 / E99 unlock — $1,250, OBDX Pro GT included

Locked Global-B controllers unlocked with the cable in the box. Stack it with a next-gen remote on Build, or order the unlock on its own.

What we do

Built on the bench, not bought from a catalogue

We reverse-engineer the calibration and the operating system itself. That means we can change things a file service simply cannot reach.

Remote tuning files

Send us your read, get a finished file back. Stage 1 through fully custom builds, transmission calibration and fuel conversions — mapped to your vehicle's actual hardware, not a generic model match.

Custom operating systems

OS-level work across GM P01/P59, E38/E67 and E90/E99: VE table hooks, flex fuel enable, sparkcut, antilag and security bypass. Every address is resolved against your target OS, then the finished image is byte-verified.

🔒

Unlock & recovery

Locked modules read and written, bricked ECUs recovered at bootloader level, checksums repaired, VIN and immobiliser alignment. The work other shops send away.

📈

Definition & XDF work

Reverse-engineered TunerPro definitions for calibrations nobody has mapped. Addresses, scaling and axis data verified in the disassembler before they reach your definition file.

🔧

Shop & dealer support

Trade pricing, priority queue and a direct line to the engineer. Take on work you'd otherwise turn away, without hiring a calibrator.

💬

Support that answers

Every job carries a ticket thread. Attach datalogs, ask questions, request revisions — all tracked in one place, with a real engineer on the other end.

How it works

Four steps, one portal

No email chains, no lost files, no wondering where your job is. Everything runs through your account.

Create your account

Read the ECU

Pull the original file with your tool of choice — bench, boot or OBD. We work with reads from every mainstream flashing platform.

Send the file online

Upload the read with your vehicle details, hardware list and what you want from it. No ECU shipping — the file travels over the internet.

We finish it on the bench

An engineer builds your file by hand, corrects the checksum, and verifies the image. It does not leave here until it is complete.

Fine · dyno · street

Flash it, then we refine from your logs and feedback — fine-tune, dyno-tune, street-tune. Free revisions for the first year.
