EL15 probably uses Hitachi ecu and OP2 is out of help. If there is SH7058 chip inside you may use SHbootmode for reflash provided you manage to upload stock ROM image. Older cars used M32R base Hitachi ecu.
I reat about a MY08 1.5L witch was reat and wirted via ECUflash. You can find this threat in a european subaru community. I would like to test it two, but th day I was at the Subaru Station, there was no 1.5L to read-out.
But it seems that, the > MY08 1.5L work with ECUFalsh
Bought Tactrix cable a few weeks ago. Already done a 2001 wrx and everything worked fine.
Today i try with a 2010 impreza 2.5i N/A, but the EcuFlash closes the interface comunication after seed key. It was my understanding that this car was supported: isn't it? It has the start/stop button, no key, but I pressed OK on EcuFlash window immediatly after pressing the start button on the car.
I found no-where infos about the procedure for the start/stop provided vehicles....
PS: After every "read try", the fans start going on-off
