from what i know about boosting an NA is the higher compression makes combustion temps hotter which increases the chance of detonation. philiptompkins if your detonating anywhere then you should not recommend timing advice, this is just going to make him detonate like you and blow his **** up. i don't mean to insult anyone, i just don't want the wrong information to be passed and then this guy is out of a car.
since the 1.8 isn't adjustable, i would recommend retarding an additional degree per psi after 9 psi of boost since the rtek 1.X's don't retard enough timing for anything bigger than a stock turbo. your afr's are perfect and safe, 11.0-11.3 is perfect for under boost. a fmic would help lower combustion temps. in addition with the fmic, to make it safest as possible you could buy a water injection kit.
I'm running it with megasquirt.
And your right, higher comp. does make comustion temps hotter and increses the point at which the motor detonates.
To compensate for this it is important to run a few less degrees of timing than your would on the same motor with turbo rotors.
annnd, for you personal attcack on my knowlage: How can you learn how far a motor with a setup that NO ONE has apparently run (or is willing to give advice for) if you don't push it a lil. I told him about my experiance with detonaion to help him not make the same mistake. I was trying to save fuel during highway cruising so I advanced it out quite abit for low RPM (3-3.5k), low boost... and the motor didn't like it... just saying.
And yeah i'm sure the FMIC is a good idea. I just thinkg running 0 deg is a lil too far out on the conservitive side. If i had to lock mine down and run 14psi, i think i'd try somewhere around 8 deg
