Isuzu Denso sh7055 1.7dth ecu is possible with pcmtuner flash? I tried Protocol 42 unsuccess.
This works fine, but you need to use an OBD breakout cable like the GT105/GT100.
The power needs to be permanent so you cannot use the pcmtuner bench cables as they are switched, OBD port with breakout.
Even the godiag full protocol tricore cable will do.
