Oh...sorry Chris...I thought you were being a wise @ss!

I have an '05 tC. If you look at [url]www.scionlife.com[/url], it seems there is an
issue with the drive-by-wire system introducing a slight hesitation when
you initially depress the gas pedal. One guy who's an engineer (and who's
experieince is quite surprisingly similar to mine-Electronics, Avaition
and Avionics and computers) thinks this is caused by the automatic
'calibration' of the throttle potentiometer by the ECU. I had figured, if
there was an adjustment for the pot, then the hesitation could be
overcome. He did too, and tried it, and the ECU compensated for it,
and...hesitation.

Like I said, I've been driving 4 and 5 speeds for over 30 years, and with
two of them I was SO smooth it was like driving a car with a CVT!! But the
tC threw me, I didn't know what it was. But, by the extremely light
feeling of the throttle, I figured it must be a d-b-w system, and then
discovered I was correct.

So, in implementing the 'fix' from Scionlife (get rubber 'feet' and place
them where the throttle linkage 'rests' against the stop) I found this
set-screw type deal. It seems to have stopped the hesitation and I can
shift now more like I'm used to!

One of the guys (the engineer, I believe) even added another spring to the
trhottle to make if feel more like a cable type linkage and provide a
little more 'feedback', something I notice is missing. I can hold my Supra
rock-steady on any raod at any speed, but with the tC I have to keep an
eye on the speedo! (But then, my Corolla GTS is a lot like this,
too...it'll get you going faster than you think you should be very easily...)

What type of Scion do you have? And, have you been to Scionlife yet?

Next task...swap the Orange LEDs in the dash for blue...!!

Also, have you found how to change the radio 'equalizer' yet?
