Firmware and dump operations online — choose a tool and see the supported blocks.
Transfer of immo data from one ECU dump to another — the donor unit starts responding to the keys and BCM/CAS of the recipient vehicle.
53 blocksReading VIN, PIN, keys and other immo parameters from an ECU dump — diagnostics and cross-checking without modifying the file.
138 blocksDisabling the immobilizer in the ECU firmware — the engine starts without binding to a key and BCM.
1 blockView and edit ISK and VIN in the dump — matching the control unit to the vehicle.
32 blocksRead and write ISN — syncing the ECU with CAS / EWS / FEM when replacing or repairing a unit.
1 blockEditing mileage and VIN in an instrument-cluster or control-unit dump — aligning the data after a module swap.
4 blocksSynchronisation of immo data across the vehicle's linked units — ECU, instrument cluster and ignition lock all respond to one key.

How it works
3 simple steps from ECU dump to ready file
Upload the ECU dump
Read the block via OBD, Bench or Boot and upload the firmware file. The system detects the control unit, processor and make automatically.
Analysis and check — free
We show which operations are available for this block — IMMO OFF, ISN, ISK, VIN. No payment or sign-up: first see what can be done.
Apply in the portal
Pick an operation — get a ready file with correct checksums. No manual edits or CS recalculations.

Frequently asked questions
IMMO OFF, ISN, ISK and VIN editing — in brief
What is ECU Tools?
A set of online tools for ECU firmware and dumps: checksum and CVN recalculation, EEPROM checksum, immobilizer off (IMMO OFF), ISN read/write, ISK and VIN editing. Bosch, Continental and Siemens ECUs on BMW, VAG, Renault and other makes are supported.
How much does it cost?
File analysis and check are free. Applying the operation and downloading the ready file — in your portal account, where the price in credits is shown.
Which operations are available?
CLONE — 45 supported blocks; IMMO DATA — 53 supported blocks; IMMO OFF — 138 supported blocks; ISK+VIN EDIT — 1 supported blocks; ISN+VIN EDIT — 32 supported blocks; ODO+VIN EDIT — 1 supported blocks; SYNCRO — 4 supported blocks.
How does it work?
Choose a make and block, upload the ECU memory dump — the system detects the block and available operations. Applying and downloading — in your portal account.
