i have an '01 4Runner LTD it has an ECT button that i push when i wanna "get on it" but is it doing anything or is my foot doing the "power boost"???

drguitarum2005

if i recall, it alters the shift points in your tranny so that they shift at higher RPMs, meaning youre in the power band of your gears for a little longer. that combined with a more lead foot will mean you get a little bit more power.
little fun fact, it stands for "electronic(ally) controlled transmission"

While we are on the subject-does it only come on certain models/tranmissions?

Not sure of exactly what it's doing in technical terms, but mine has it too and it tightens up your shift points. In other words, it extends the shift points of the transmission so that the engine winds out more between shifts, or in even simpler terms, it waits to shift at higher speeds than it does when the ECT is switched off. Sort of does what you would do when driving aggressively with a manual transmission.

someone told me that it tells my ecu that my engine is still cold and it dumps more fuel in to it..

humanoid

Uh.... no. drguitarum2005 is correct. It just makes your tranny shift later so you'll have more pull while racing that Ferrari!

^ Ditto ^

And what's up with calling it the ECT button? The truck has an ECT. But the ECT PWR button puts the ECT into ECT PWR mode

ETRNL

ok but what is this???
ECT MOD

drguitarum2005

completely different ECT. that stands for "engine coolant temperature" and is a way of tricking the computer into thinking the engine is cooler, delivering more fuel. that mod and the ECT mentioned in this thread are unrelated.

Elton

it changes the shift points also its been talked about

ok so the ECTPWR has nothing to do with a/f mixture...
dose any one still have an active link to the ECT mod???

i think its pretty much mental

I realize this is a really old topic BUT... i also wonderd this and used the Search Button but if this is to help it shift in a higher RPM what is O/D For?? Doesnt O/D do that also? So if i used both the effect would be?

drguitarum2005

O/D is just an extra gear (your 4th gear on the common toyota auto) to lower rpms for high-speed cruisin like on the freeway. it has nothing to do with when your transmission shifts. ECT makes your transmission shift at higher RPMs, thereby letting your engine spend more time in the "performance band" of RPMs, giving you a little improved response and speed.

Dare44

o/d is basically taking a gear away from your tranny, the ect just shifts at higher rpms to give u a better acceleration in all the gears

Dare44

u beat me

JacobHum

Ok sweet thanks. So if i plan on racing something should i use it?? And according to some topics it increases MPG or Stays the same! So ill just use it all the time. O would it also be Dumb/Smart or normal to use O/D and ECT at the same time?

Dare44

i wouldnt use o/d at higher speeds, but i always have my ect on and the mpg are only affected noticably if ur on the skinny pedal, as opposed to being on it without the ect
