▚ Service · ECU Security
Modern control units ship sealed — encrypted, checksum-protected and closed to tuning. We open them. Full read/write access on the platforms that shut most tuners out, done at the bench and verified before it goes back in the car.
▚ What we unlock
The units below arrive from the factory with write-protection and security that blocks conventional tuning. We handle the read, the unlock and the checksum-correct write-back.
Full firmware access on the locked next-gen Type R ECU — read, calibrate and write with write-protection bypass and correct checksums.
Same platform, same lock — opened. Read/write access for calibration on the DE5 Integra Type S control unit.
Full read/write and calibration access on the FK8 Type R ECU — the platform that put us on the map before the FL5 arrived.
▚ What's included
Original firmware pulled and archived before anything is changed — a clean factory image to fall back on.
Factory TPROT and security defeated so the ECU accepts a modified, tunable file.
All checksums recalculated and corrected so the unit boots and runs the new calibration cleanly.
Work done on the bench where OBD access is blocked — including boot-mode reads on sealed units.
Full ECU cloning and recovery of bricked or corrupted units back to a running state.
An unlocked file hands straight to our calibration side — one shop, unlock to finished map.
▚ How an unlock runs
Confirm the platform, security type and whether OBD or bench access is needed.
Factory firmware pulled and backed up — the original image is never lost.
Write-protection and security bypassed so the ECU accepts modified files.
Checksum-correct write-back and a bench verification that the unit boots.
Hand off to calibration, or return unlocked for your own tuner to work with.
Intended use. ECU unlocking and modified calibrations are provided for off-road, track and competition use. Modifying emissions systems or running a modified tune on public roads may not be permitted in your jurisdiction. It's the owner's responsibility to ensure any vehicle is used lawfully. We always retain your original factory file so the ECU can be returned to stock.
▚ Get started
Send the platform, the ECU part number if you have it, and whether you want a tune to follow. We'll confirm the unlock path and turnaround.
