Hi all,
Hoping someone can help. I’m trying to read the ECU on my JDM Subaru Impreza STi with a genuine Tactrix OpenPort 2.0, and I’m stuck. RomRaider logger works perfectly — I can view live data and logs — but ECUFlash refuses to read the ROM.

Here’s everything I’ve tried and confirmed:

ECU ID: 4304594005

CAL ID: A4TJ121B

Vehicle: JDM Subaru Impreza STi, drive-by-cable, 16-bit ECU

Tactrix Firmware: 1.17.4869

Tactrix Driver: 1.02.4870

ECUFlash Version: 1.44.4870 (I’ve also tried 1.29 but had DPinst64 errors)

RomRaider: Logger works, SSM fast-K communication confirmed

Green test connectors: Connected (fans come on, test mode active)

Black 2-pin flash jumper connectors: Connected

Definitions: Confirmed correct XML for ECU ID, flash method is wrx02, memmodel 68HC16Y5

Dummy ROM loaded in ECUFlash before attempting to read

Tried 'Test Write' – fails

USB cable confirmed working, COMMS confirmed via RomRaider

Any ideas? Could it be a flashing lock or something physical I’m missing? Not 100% on the flash jumpers.
Has anyone had to do anything special for a DBC 16-bit JDM STi with this CAL ID?

Cheers in advance!

Hi all,

Black 2-pin flash jumper connectors: Connected

disabled - Black 2-pin flash jumper
6 pin or 2 pin connectors needed

Thanks Cortin. After the 500th time of searching I've finally managed to find the elusive white 4 pin connector this evening and grab a successful read. It was tucked way up out of the way, not near the green test connectors like I was expecting.
