I have a GoPoint & TomTom with Iphone4 runing with my 997.1GT3 RS and as u can see the video below the throttle position is not sensitive enough. Big lag
RPM change felt filtered in gear change.
Any advise on the setting?
Anything i can do in the expert setting?

Hi John,

I had a 997.1 myself and typically received OBD update rates of 2 or 3 Hz only. OBD is not optimized for real time viewing (it is designed for workshop emission testing), so even with a later 911 (the 997.2 makes 7 Hz as an example) you can never expect to get hand movements as instantly as you see it on your dashboard. LapTimer adds interpolation in addition, which makes rapid movement even slower (not having this interpolation would result in very ugly "jumps"). So from my PoV the result in the video above is probably the best can do with your GT3 (and I think it looks pretty good!).
