Good to knowAbout Immo Off files
Immo off files are modified ECU dumps with the immobilizer function disabled. They let the engine start without the original key, immobilizer box or body control module, which makes them the standard solution after an ECU swap, an engine conversion, a lost-key situation or a faulty immobilizer system. Each file is prepared for a specific ECU model, hardware number and software number, so the modification is done on the correct base and the rest of the calibration stays untouched. Files are ready to write with tools such as KESS, KTAG, FLEX, PCM Flash or a bench/BDM programmer. Always match the hardware and software numbers on your ECU label before flashing. Buy securely, download instantly, and request any immo off solution you cannot find in the list.

Good to knowImmo Off files: frequently asked questions
Is an immo off file safe for the engine?
Yes. Only the immobilizer check is disabled; ignition, fuel and boost maps stay stock. The engine starts without a valid key signal, which is why immo off is used after ECU swaps, engine conversions and immobilizer failures. Write the file with a bench or OBD tool that supports your ECU and keep a backup of the original read.
How do I know that a file matches my ECU?
Compare the hardware number and software number printed on the ECU label (or read by your tool) with the numbers in the product title and attributes. They must match exactly; a different software version is a different file. If you are not sure, send us the numbers and a photo of the label before buying.
How is the file delivered?
Immediately after payment the file appears in your account under Downloads and a link is sent by e-mail. The file stays in your account, so you can download it again later. Files are delivered as ZIP archives containing the read exactly as it came from the unit.
The file I need is not listed. Can you supply it?
Yes. Use the file request form or e-mail us the vehicle, ECU model, hardware and software numbers. Most requests are sourced within a few hours, and the file is then added to the shop for you to purchase and download.
