My tuner has been doing a lot of research, he talked to TSI, Procivic, AEM, and Shawn Church, and it seems to be that the AEM FIC is just tricky as hell to tune just right. One reason being that the SI's are all slightly tuned different out of the factory. Anyway, I was told that once the FIC is tuned right, it will do a jam-up job.

Thanks for your reply.
1 from above) I can tell you for sure that the stock ecu doesn't recognize any crank signal for about 2 second and then when it does, it immediately fires. Since the FIC sends out a signal processed crank signal, but guess is that it takes the FIC a couple seconds to determine the crank signal, and that there is no way to change this fact.
2 from above) I haven't noticed any hickups after 3000 personally on the TSI turbo car I was tuning. It was noticed by the owner of the car. There is nothing in the tuning that suggests anything is wrong.
I actually think the FIC is quite straight forward. I havne't seen anything really strange about it. All I've heard about is bad wiring and bad tunes. So far so good in my opinion. Only issue that really remains for me is the tip-in throttle, and I'm still trying to determine if it's a problem with the tune or the fundamental FIC/stock ecu setup.
