So the problem is Porsche's ME7.8 and no decent commercial logger available. Durametric can do something, but no individual cylinder ignition retardation values (ie knock pull). They do not have any interest in developing their product. There are others like Maestro or Cobb AP3, but they seem to require a connection to certain (overseas) tuner.
My tuner, who mainly does Audis and VWs, pointed me to this direction. He tried to use the logger (version he uses for VW and Audi) but with limited success, only few actual values were available. Can anyone help with this....ie is there a way to make ME7logger to work with ME7.8?
