We use a V88 marine on kawasaki jet SKI.
We use the same setting like you define in your post reply.
We calibrate the offset to 244° and the timing delay to 160ms. (200ms seems to be better)
the coils are the OEM and the module is a Bosch 200.
the timing advance doesn't move when the rev up and down from 1000 to 7500 rpm.
with the calibration OFF we checked the igniton timing advance.
when we check the timing advance on the crank we found that the ignition timing advance decreases when the rpm increases.
we use a simulator whit OEM reluctors. the ignition table is fully filled in with the same value. all the corrections are disabled.
With 20° as reference , the igntion timing is right at idle or 2000rpm then the advance decrease to 12 degree gradualy when thr rpm increase.
waiting for your help
