EDC17C42 virgin EEPROM compatibility by Bosch number

Brams_OA · 21/10/2026, 12h46

I am checking a safe donor ECU workflow for Bosch EDC17C42 TC1767. The donor identification is Bosch 0 281 019 075 and Renault 237101Q74R. Bench backup is complete: 2 MB internal micro flash and 64 KB EEPROM, with two identical reads of each area. When selecting a known-good virgin EEPROM, is matching the ECU family and memory size sufficient, or must the Bosch and Renault software/hardware numbers also match exactly? The final plan is checksum verification and secured learning with Renault CLIP. I do not want to use an immo-off file or write an unverified dump.
