Does someone have any experience with flashing the ecu of a Subaru Impreza WRX STI from 2006 with SH7058 controller by the Piasini tool? This Denso ecu has 4 plugs.
WHen using the obd option in the car I get no communication, so I have removed the ecu.
I found a connection diagram to connect +12V and GND to the connector and a lot of wires to the flatcable connection of the Piasini, but which option will I need to use to in the Piasini software? SH toolbox?

I have connected the flatcable to the solder pads at the ecu PCB, connected +12V and GND to the connector, but still no communication.
Nobody ever tried this ecu with piasini?

Hi,
good solution is tactrix open port by obd,
Also you can recover in boot mode
