Grouping all of the "FI" cars together (all having the same outstanding performance) is really silly too and most FI combos will only run really well in outstanding conditions becauase of the small throttle bodies. Also worth mentioning is that most are 'batch fire' systems with a single coil, fuel injects when the valve is closed, how is that so "dominating". Yes it's possible to individually cylinder time these, but, so can a carb combo! As you stated, only mutli-pak coil systems can use the very expensive and time consuming sequential system for individual cylinder tuning.

I can't wait to hear the outcry when the newest batch of FI cars hit the track in '09.

Bernie,

You don't need individual coils per cylinder to run an engine sequentially. All you need is the ability to know cam position relative to crank position. The LT1 has always been capable of running sequential, thus individual cylinder tuning
