So me and my best friend where chilling, and after a few drinks we decided to tinker...



Lately my SC400 has been feeling sort of sluggish, iv been looking into ways to improve my throttle response with out having to spend thousands.

SOOOO we tighten the HELL out of my throttle cable

Its easy to do, and right now my pedal has less then 1.2 Cm of play and revs out faster.

First start off having a friend put his foot on the pedal and LIGHTLY press JUST enough till you fill the throttle plate start to catch, should only be like an inch or so, if that.


Then Mark with calk stick or something to show where your throttle begains to engage

Then all you need to do is Losen one bolt and tighten the other to the point of the mark, JUST before the throttle engages





Simple, and some may have already done this, But i wanted to share with the SC community my findings, its awesome, throttle response is absolutely insane and it revs up so much faster and under load the acceleration has increased dramatically with out affecting the idle speed or anything

I don't see how tightening a throttle cable gets better throttle response.... I think its all in your head

I did this on my car not too long ago, it defidently made a difference, after years of tear that cable got loose and it had a good 1cm or 2 of play at the gas pedal now it's instant engagement.

its not going to give you better throttle response perse. it will respond the same way just you have to press the pedal less. its a good mod for an older car and a saggy throttle cable. if you want "real" improvement in throttle response go ITB's .

be careful to not tighten it to tight or the throttle might stick.

That SC looks like it does not have TRAC-CONT.

My throttle definitely feels like it is meant for the median Lexus owner.

This is good info man; thanks for sharing.

Yeah very simple to do, Great little Tune up project, only took like 4 min and makes a world of difference

I have plans to pull my trac.-control off as well. Did you go to the trouble to remove the extra plate in the throttle body? Im going to scrap my C.Control as well.

Man that is weird, JDMs SC has an insulation blanket on the underside of the hood, and my 95 SC4 does not.
