made my s4 turbo much smoother to drive
guys, I've posted this before under an old subject heading... but I've heard a fair few people whinge about this, and it's made a huge difference, so here it is.
I hope it makes someones day as much as it did mine
my s4 turbo always felt a little jerky changing gears, or backing off / getting on the throttle. Not the sort of jerk a passenger would 'notice' and wonder what it was, basically just a bit of un-smooth operation that I figured was 15 years worth of wear and tear on bits.
I eliminated the throttle cable freeplay, so the throttle was constantly cracked * very slightly* open. Reset the tps so it was back to 1k ohms at this point. Bolted it all back up, and went for a drive. Idle is the same. Engine braking appears the same. It's *so* much smoother changing gears, and driving in general, I am quite simply amazed at the change.
I'm told throttle cable freeplay is specified because of expansion / contraction of bits, wear on the cable, movement of the engine, and possibly a few other things. I've not noticed any negatives so far, but it's so much better I'd be happy to put up with a few minor ones...
Would love to hear a response from anyone else that tries it.

any idea just how much premature wear ted?
if it stretches slightly it'll just set me back to having freeplay, won't it?

yeah the t2 cables seem to bind when they get old. you are supposed to have a little play/slack in the cable to keep the throttle from hanging/sticking open. the 1st gen gsl-se's are really picky about that, if you have the throttle cable too tight it wont idle at a consistant rpm. the t2's dont seem to care as much.
