Speed cut 1992 AE101 GTZ

[pjay]

just a quick question..

is there a speed/fuel cut between 220 - 250km/hr?

I understand there is one at 180..

[Mr GTZ]

I understand there is one at 180..

I have never experienced any sort of restriction at 180kph, she just wizzes right past it....
Although at 220kph I do experience a unfortunate cut-out of some sort. Be it a boost/fuel or speed cut I am unsure.

yeah like a "voom" noise and the speed drops. then it revs up again. then "voom" ..complete loss of power again

interesting noise but that will be your speed cut at around 200

You will be traveling around 180km. Your speedo is just really wrong.

My speedo shows 210 when i hit speed cut, but if you look at the revs, and work it out, you can see your speed is about 190.

Factory speedos pretty much all read way high at that speed.

Also what you guys need to remember if someone can't "take out" a toyota factory speed cut.

If you cut the speed sense wire your going to get a engine check light up. The only way is to modify the signal, and you will be able to see the box or componants that are doing that modification.

So if you have a factory ecu, and there is no rangi looking box on it, then you WILL have a speed cut at around 180km/h. No matter what your dreaming speedo says.

i've done mine with a gps and it was abotu 200 (waiting for it to catch up)

now i dont really care as i rarely see that speed, and when i get that high the needle gets pinned to the bottom rather quickly

[slighty_sykotic]

ok, but your needle was showing way over 200 wasn't it?

ive removed speed cut already. it clocks 180 in 4th. then through to 5th and the "voom" noise comes in at 5000revs in 5th gear.

Is that noise not normal?

my needle only goes to 180.. do you have a aftermarket dash? cool! i want one

cut the purple wire

Which is why you are getting a cut at 5000rpom in top gear

Make one of these up and it should fix it

this one?

I've measured mine with my RSM, and its cut between 180-190 everytime, I have the feeling that there is a thread somewhere discussing the speed cut, and most people agreed it was around 180-190, but could be higher/lower in diff cars depending on wheel size (my rsm is adjusted from factory size to my 16s, so RSM is nearly dead on)

hence why i said gps, my needle is pinned to the bottom way passed the 180 mark at that point, gps is pretty accurate at speed
