Default Lift off det

Morning all.
I've been logging a few runs on datalogit and have noticed i'm getting det 40/50 on lift off?
the injectors are at 0% at this stage and timing is at about 35 so i should not get det right?

Exactly why you are getting det.
Look at your logs and you'll see the ignition timing increase when you lift off.

Its happenning at high rpm and load as i let off but stay in gear and trails down the scale a bit.
Ignition timing there was 45 which i then lowered to 35 but still get the knock .
as soon as it lowers below 5k rpm it goes.
i'll give it another run at 25 ignition
i did'nt think knock was possible on over run when no fuel is going in?

Not exactly subarus I know but the following link has some lift off det experienced by John Banks so there may be some answers in there.
