well after plumbing in the charger i am now stuck on the igntion timing. hope somebody more experienced can offer some tips.
how does this igntion map look for a standard 2.0l zetec with supercharger. I am happyish to sort the fuelling but I struggle to know whats a good
map for ignition.
I have retarded the igntion as boost increases over my N/A setup, roughly 1 degree per psi. How do you set ignition to its optimum? do you need a
knock sensor to set igntion, EGT sensor?
Any thoughts and tips on my map would be greatly appreciated.

I would keep making small adjustments and test driving. If you get knocking back off a little.
You probably want full advance by about 3500 - 4000 to get the best power.
I've limited experience with boosted induction but I would tend to agree with Andy.
I would expect to see the advance "all in" by about 3500 - 4000 rpm. if the same rules apply as for NA induction.
AFAIK there is little point in increasing advance past these figures but as I say I don't have much experience with boosted engines.
You're probably better to ask this type of question on the MS forums to be honest.
