yet another cam sync question

on the sierra DOHC engine, I have a cam vr sensor that's pointing the camshaft lobe.
everything works fine for sequential injection. - well - until around 4000 rpm.
after then, when revving, bursts and blasts start.
is that a 'noise' problem ? what if I choose the "disable cam sync above 1000 rpm ?

Try to log the 2 trigger parameters
TRIGGER ERROR
TRIGGER SYNC STATUS

there are NO errors / syncronization loss.

i had the same problem yesterday and took a look into manual.
i think i solved it now, by noise filter.
i set 700° of crank angle to ignore any cam trigger.
maybe it will help you too
