I wonder if anyone else has noticed the way the GT computer behaves. I already know that the engine makes no power until it is fully warmed up, there is no question about that. The computer waits for everything to look perfect then will allow the optimum timing, boost, fuel, etc.

I am starting to think the computer might do one last check before it will fully optimize everything for max power. It seems that after it is warmed up the computer wants to see a full throttle acceleration for a few seconds to verify everything and possible to verify knock/octane. I am not sure if I imagine it but the first full throttle application after the car is warmed up is never as strong as full throttle applications after the initial one. After my car is warmed up the first full throttle application will just barely start to break 2nd gear loose from a roll at 3000 rpm, but the next full throttle application from a roll at 3000 rpm will easily break the tires loose and sometimes do the same with third gear. I have the 6spd so I can't say if the dct behaves similarly. This is with the Racechip at 5 on 87 octane

So I feel like the computer needs the engine fully warmed up and then one full throttle sample to decide how to set everything for full power delivery. Am I crazy or has anyone else noticed this as well?

My car is a dct but I have noticed something similar too... sometimes my car will idle for a half hour before I drive off and it’s a slug the first 1/2 mile or so..

That would make sense. There is definately something going on with the ECU that effects the power output.

Perhaps we also have this embedded in the ecu?
Certainly am curious. It wouldn’t be the weirdest thing to have something like that in our ecu.

I notice if the DCT is in normal it’s sluggish on first launch but if I’m in manual mode it holds revs.
That we are familiar with. The part we are talking about is comparing the power delivery in sport mode only. The computer seems to be looking for specific things to decide when to allow optimum spark, fuel, boost etc.

I am sure this was discussed but what experience do people here have with obd2 devices that can display engine readings with iphone? In particular boost and or MAP

The Car Scanner app will work fine with any Bluetooth OBD2 device just like Torque on Android does. It's not as good of an app as Torque (especially Torque Pro), but it's functional.
