Met Ben a Marine engineer on the boat today. He had already adjusted the fuel delivery rail on his last visit and today he brought the laptop. Connected it up entered the software programme and smiled. This is your fault as he pointed to a very expensive looking piece of both mechanical and electrical orientation. He took it apart and fiddled a little put it back together and bingo, sorted.
It turns out that the part is boost sensor that is connected to the turbo thingy. This tells the ecu what pressure is being delivered, without this info the ecu thinks something is amiss so only gives half the available power to save the engine, very clever but annoying all the same.
As an aside Ben asked me to quickly fire her up just to test and wow what a difference his efforts had made. Until now when starting from cold I had to crank the engine for several seconds before she would fire up, today she started instantly. Also normally we would have some grey smoke whereas today there was none so I am well happy.
Asked Ben for the bill and that made me even happier, well impressed with him.
It just goes to show that it pays to use the right people for the job in hand
