[CA] Auto tack or auto turn

I have a new ev1,P70 and tiller pilot, just connected to existing e57 and St60+ set.

The pilot seems ok, but when in auto mode and press together 10 and 1 keys to tack, the pilot aims for 90 degrees. This boat is a catamaran and I want to change this to 100 or even 110 to make sure she makes the tack. I can trim afterwards.

Note this is not in wind mode.

any help greatfully received.
