The test plug seems to make no difference, and the fuel pump does prime like it does with the usdm ecu. I can swap back the usdm ecu and read/write just fine. Swap back the jdm ecu and i can not access it. Neither with the romraider logger with the ign on and test plugs undone, or with the test plugs connected trying to use ecu flash. I've been flashing my 02 ecu for a few years now, so I'm pretty familiar with how finicky they can be as far as when you turn the ecu on and hit the read button.

I get the same error with the ecu on or off.

I just feel like the ECU isnt coming on or something. I'm kinda stumped. I've spent a couple hours just trying to read the ecu at this point.

I've also encountered the same issue this week with a collegues ej207 swapped 2002 TS.

I can log fine, read the learning view, have the car in test mode ( pump cycling ) but cannot for the life of me read the ecu.

I've tried ecuedit ( admin mode ) and ecuflash with same results.
