Bosch ECU Hardware Cross-Reference is a small offline lookup application for checking a known Bosch hardware reference against its packaged database. The interface provides a reference-hardware input, a hardware-model result and a search action. It is useful for the first stage of donor ECU research when a technician has a complete label number but needs a normalized hardware family or related model entry.
A database result is not a replacement authorization. Bosch numbers can share housings while differing in processor, memory, power stage, bootloader, calibration, immobilizer relationship, connector population or vehicle application.

What this resource is for#
Use the database to organize hardware-number research before comparing the complete donor and original identities. The output should narrow the search, after which the technician must verify OEM part supersessions, connector and circuit details, software compatibility and required adaptation.Confirmed functions#
- Accept a Bosch hardware reference
- Search the bundled offline database
- Display the associated hardware-model result
- Support quick normalization of workshop inventory labels
- Provide a repeatable starting point for donor ECU comparison
Supported vehicles, controllers and data#
- Bosch ECU hardware references present in the packaged database
- French interface labels identify the input as reference hardware and the output as hardware model
- Coverage count and update range are not claimed beyond successful database matches
- Vehicle, engine, transmission and market still require separate confirmation
- No reading, flashing, cloning or immobilizer function is included
Package contents#
- Single Windows installer containing the lookup application and database
- Original interface screenshot
- No firmware, calibration, wiring, programmer or driver package
- Installer is unsigned and was inspected statically without installation
System, hardware and interface requirements#
- A dedicated Windows workshop computer or isolated virtual machine with administrator access for legacy software where required
- Enough free space for the extracted package, immutable originals, working copies and verification outputs
- A second trusted application or OEM document for checking identifiers and results before any vehicle-side action
- Current backups and a documented recovery route before changing configuration, EEPROM or flash data
- Stable vehicle or bench power whenever a connected diagnostic or programming step follows the offline work
- Complete Bosch number, OEM part number and donor/original label photographs
- OEM electronic parts catalog or manufacturer service information for final supersession checks
- Bench identification or trusted diagnostic readout before programming
Recommended workshop workflow#
- Record every number from original and donor labels
- Search the Bosch hardware reference exactly
- Capture the returned model and compare with OEM application data
- Verify processor, memory, pinout, power stages and software family
- Plan cloning, virginization or programming only after compatibility is proven
- Identify and test the module on the bench or vehicle under stable power
Compatibility limits and responsible use#
- A matching family name does not prove compatibility with every hardware revision, software branch, memory layout or market
- The package does not replace OEM service information, ownership checks, qualified diagnosis or a tested recovery method
- Security and immobilizer functions are for authorized repair of owned or customer-authorized property only
- Legacy unsigned executables should be isolated and independently scanned; no malware-free claim is made
- Never post VINs, keys, PINs, active seeds, calculated responses, customer files or proprietary controller dumps publicly
- Do not buy or install a donor solely from one returned hardware family
- The offline database may omit supersessions or contain historical entries
Troubleshooting#
- No match: remove spaces cautiously and retry the complete label number
- Several labels look similar: compare all Bosch and OEM suffixes
- Returned model conflicts with OEM catalog: use current OEM data as authority
- Installer fails: use an isolated compatible Windows environment
- Donor cannot communicate: stop and verify pinout, boot state and hardware rather than forcing programming
