The ecu is a 1997 flashable ecu which means you can take it to any tuner and get it reprogrammed to match your needs. You cannot do this with a 1996 ecu.
The ecu was sent to Porsche, Germany by David Raines at Powerhaus in Arizona to get reflashed to 450HP....so, it's a factory job. You may want to call David Raines at Powerhaus and tell him it's the ecu that went into the silver America Roadster conversion done for baseball player Marc McClemore. He will remember the car. I now own it, but the original transplant was made by him and all work was done first rate including sending the ecu to Germany for factory flash according to David Raines.
