Throttle response
So, two things conspired to make me think my Z was not quite as fast as I had hoped.
1. The 4000 rpm limit obviously forces you to short shift
2. The DBW throttle in my Jetta was not nearly as linear as that of the Z
To drive smoothly and keep it under 4000 I found myself using only about half of the pedal travel. In my Jetta that would have been 80% throttle. The night before last I kind of rolled into it a little deeper and - OH MY GOD!!!!!
The throttle is actually very linear - half pedal, half throttle
I had no idea. I was starting to accept the lower than expected power level, and was mentally using the sublime handling to justify the purchase. Now I have to say it is a darn good thing the car handles as well as it does, because with the power it has, bends come up pretty quickly. If anyone has been really babying the car like I have, just once or twice in second gear give it the boot. I am still smiling.

good observation, I can't wait to get my car. I like the fact that people like you are giving your impression and advice, so that when I get my car I will know what to look for.

From the SCC review...
"The Z's electronic throttle also takes some getting used to because the pedal movement to throttle opening ratio is 1:1. Drive enough Porsches and BMWs and you'll get used to their aggressive electronic throttle mapping that opens the throttle more than you actually move the pedal. The Z's throttle opening, and the resulting power delivery, is more linear and honest, much like a mechanical throttle. After a day or so, we became convinced this is the way all cars should be. You want more power, move your damn foot more."

I'd have to agree. The throttle is great, like a fine instrument very responsive and predictable. I'd have to say the same about the brake pedal too, very linear without a hard, sudden pinch that you get with some cars.

okay so someone want to help a rookie
I understand the concept of a RPM or throttle limiter...but where is it and how is it configured? who configs it, can it be turned off? can someone just give the detailed rundow of this and how to best use it..
thanks.
Chris
thanks.

Bishop_TX, if you are refering to my comment about the 4000 rpm limit I was talking about the rpm limit given in the owners manual for breaking the car in. There is no physical rev limiter at that engine speed. I am using the car's built in shift light to help me keep under that rpm. It is on the dash and very easy to set, but it doesn't limit the speed just warns you when you approach the preset speed.
If you are talking about the car's actual rev limiter, I am not sure where the Z's is, but it probably changes the timing or cuts the throttle at ~6700(?). This is to keep you from blowing the engine up and without custom work, cannot normally be changed or removed.
Hope I answered your question
