By the same logic, stick a g-meter in 550 and with similar amounts of practice it's reasonable to assume that in time you will beat the magazine numbers as the 545 owners seem to have done.
Thats what I'm thinking... its all relative...

Anyway, I finally got around to reading the G-Meter manual after all this time. I found out that we haven't been using the rollout feature.
Znod and grogan545i, do the both of you use this feature?

The way I launch it is Left foot on brake right foot on gas... I let off the brake fairly fast and as let off I feed gas... Kinda like driving a manual and letting out the clutch... Seems to be working for the IS so its ok for me. 
If Brian Will let me I'll would like to try to do one or two launchs on a 550 and see how it goes...

I'm betting you can. Less gas. No spare. cold weather... under 5 for sure. I bet my IS can get under 5 too... I had too much gas in the car this time and still have the spare and all carpet in the car including the tunk carpet matt... thats heavy.

If you did not set this feature in your GT2,the default value is 12".Both Zman and myself use the 12" rollout setting.This most closely imitates drag strip conditions(the stage beams are 12" apart).In order to use something other than 12" you must go into the program mode and change it.I tried using 0 rollout when I first started testing.All times were approx. .3 secs longer.
So it really doesnt make "that much" of a difference... meaning our 545s and 550s here should be getting MUCH better times than 5.7 <_<

I guess the next question would be pitch settings. I remember Znod mentioning we should've made changes. Is the pitch the same for the 545/550? I'm sure it's different for the IS350. I'm doing a search right now...

Ok, so I don't have to modify the rollout setting. Leave it at default of 12". Man, I thought that it was 0 and by adjusting it to 12" my times would've been better.

Good one g-man. The weather helped you a tad. I looked back; it is one of your 5 best on an adjusted basis. So, give me a few days and I will substitute it in and change your average here. I still plan to get a few more in before the good old hot weather is gone.
