IMMO-OFF

Saab Trionic · VW/Audi Bosch ME7 · BMW MS43 — auto-detected from your file

Upload your ECU read, pay, and download the immobiliser-off file in seconds. We auto-detect the ECU, kill the immo, and repair the checksum so it's ready to flash. If we can't do yours cleanly, you're told before paying — and you're not charged.

Version-locked & byte-verified

We only hand back a file we know is clean — every patch is validated against known-good reference files and the checksum is verified before you download. If we can't process yours cleanly — wrong file, unsupported version, or a read we don't recognise — you're told immediately and not charged. No guesswork ever gets written to your ECU.
