Were not to sure what's caused the PowerFC to go. It's reading all 0's now in place of the map. Martin at MB (originally mapped the car) thought it may have locked itself but without seeing it couldn't be sure.
I've left it with Garage-D as I don't have access to a trailer so couldn't get it to Martin. Instead it will be mapped by Greg at ProTuner this time round.
I heard from Daragh at Garage-D today. The manifolds finally arrived which means they can start work on fitting the cams/mani and ECU then we can get it booked in for mapping. When I last spoke to Greg he was fully booked for a fair few weeks though so I don't think it will be ready by the end of September
