Excellent work Jim.

Some progress tips for you.

Get her fully warm and map the sites your interested in, buut make sure the 0 - 2000rpm areas are fine under all light and trailing, static and trailing throttle conditions.

Between 14.4 and 15.4 you will notice very little fuel economy difference, but you may gain or lose as much as 10% torque between the 2, and this translates to smoothness, so for now, id aim towards 14.4 if your not going to enable closed loop.

If you ARE going to enable closed loop, make CERTAIN your base map is slightly richer than lambda 1, for a couple of reasons im a tad too tired to type.

Cold start mapping is LAST.
NEVER adjust the base maps you know were correct when warm. Keep all adjustments within the cold running adder maps or you will be chasing your tail for days in between "Runs great cold but crap hot" & "Runs crap cold but great hot" LOL.

Now you know why i want the car for a week if teh customer wants his cold start and drive 100% correct.
