Guys;
A number of posts on the very good GTROC UK RB30 thread refer to RB ignition scatter at >4500 rpm due to the CAS set up.
The last few pages describe a problem whereby there is significant ignition scatter due to cam belt flex affecting the CAS, and in particular the crank flex affecting the crank pulley and in turn the cam bet and CAS even more at high RPM + load.
A Datalog example to illustrate the problem is provided.
Theory seems to be that this can be alleviated by use of a crank trigger or ring gear trigger which makes sense, but the existence of the problem in the first place interests me. The thread is here;

I'm not viewing their findings either way as I haven't heard of it before, but there appears to be some evidence to support their argument.
Can anyone shed some light on this?
Cheers
