Hi everyone, I’m looking for the correct stock ROM and definition file for my ECU. I wasn’t able to read the ROM using ECUFlash — it seems my ECU might be locked or unsupported for reading.
Vehicle details:
Model: Subaru Impreza (USDM)
Engine: FB20B
Year: 2016
Transmission: Manual
ECU ID / ROM ID: EA1U210C
If anyone has:
A stock ROM for EA1U210C or a compatible one
A valid RomRaider XML definition
I’m using a Tactrix OpenPort 2.0 + ECUFlash + RomRaider setup.

there isn't really much/any support for the FB engine cars - if you can get ecuflash to read the rom and post it up someone might get to working on it at some stage. Meantime if your busting to get tuning then something 3rd party like subaruEdit will let you read/log/flash/edit the rom.
