Remember if you skim and change compression too much you cant change the ignition timing.
Theres a guy on RSOC who has the ONLY computer capable of writing to the original ecu, bought direct from AFT ( Who made the ignition system ) and he can supply on a reconditioned for old basis for different specced engines. May be of use to you, if you need to know his username etc i'll see if I can dig it our for you
