Hi All
Removed the EC3 and reinstalled the EC2 this afternoon. So I=E2=80=99ve got b=
ack the coil and injector diagnostics. Should also have my backup CAS and au=
totune.
Still pondering why the diagnostics and autotune weren=E2=80=99t working on t=
he EC3.
Hope to retune early this week before getting back to flight testing.
