I have a 2010 Saab 9-5 with the 2.8 V6 AWD powertrain, that I would like to swap to manual using opel parts, in addition to that i was wondering if it is possible to flash the engine control unit with the manual flash from an insignia opc?. This is the main issue i have to resolve before starting this project. They use the same Engine control unit per part number as well.
