Would this mod hurt my car?

[atclate]

So, I have read the thread about tightening the wires connecting to the throttle body would make my solara faster. One is the throttle position, and the other one is for the transmission(mine is auto).

I have tried both, and here is what I think:

I think the TB one feels like all it does is stepping on the gas harder, cos It gives me around 1200rpm idle speed with a hot engine, when it should be less than 1000. So, I'm just tightening it so much that it responses right away when I step on the gas. (I don't want to waste the gas when I'm at the stop light)

I think the other wire is really making a difference. After tightening it, the transmission is responding quicker, and it pushes harder. I'm looking at the rpm, and the same rpm gives me more push. This is why I'm tighening this wire as tight as possible(I made it so tight that the bolt is almost pushing off the rubber thing, if you understand what I mean)
But I wonder if this is actually hurting my transmission/drivetrain by putting more pressure on it or something, or maybe wearing some kind of "clutch equivalent on the manual". (I don't really understand how automatic transmissions work)

I'm just trying to find the sweet spot between performance and reliability.

i thought the "other wire" is the wire connected to the cruise control ? if u trace back to, following the wire, i think it does link to the cruise control.
it might just be your FEELING ... correct me if im wrong.~

nah im pretty sure youre right /\ -- i did this mod a few months back for the tranny line, changing the pressure in the TB by tightening it to get shorter auto shifts it does work. buuuut if you go too tight then at WOT you lose a bit of power, seems to be about right.. i fooled around with it for a while

If you really feel the need to tighten the throttle cable. Start by tightning it with the car running untill the RPMs rise a little then back off a 1/4 turn and you should be set.

Yeah i did this mods a couple weeks ago.
I did notice that i did lose a little speed at the top end, but shiftin' faster is nicer, IMO.
I didn't turn mine that much either.

Oh~~~ I didn't realize the tranny wire would make me lose WOT power.
seems like I'd need to tune it so that I get the most power at my daily driving level.

And I'm guessing it doesn't hurt my car...

[fastsolara]

so, this does something for the autos, not the manuals

[Eye8Pussies]

it's just adjusting the kickdown cable...


so...no, it won't work on a 5-speed, since we can shift as fast as we want anyway

i did it early in the summer and my car is fine
