There must be a way to remove the rev and speed limiter without e-manage or other computers, is anyone good with ecu's to figure it out yet, because it was proven to be possible with just adding a piggy back. So it just has to be a matter of adding wires and putting a resistor or watever electronic hardware to make these changes, (somebody disect their e-manage) lol....not comparing our ecu's to honda's but i know they have like chipsets they can do it all and save hundreds....if its not possible let me know so i can start saving up for a e-manage or uni
Well, I am sure you could design something.
But the car is gear limited not much further up in speed, you will never see 127 on 1/4 mile, it is going to run out of speed regardless due to power restrictions, etc. And on the rev limiter, you will just shell your motor if you go much higher very often unless you build the motor. And you wont get much out of it.
So I guess what I am saying is that anything is possible, but pretty much pointless in this case unless you are putting some serious money into the car to make it a seriouis competitor.

im just in it for the top speed remover because i hate when some cars just pass you when the limiter kicks in id like to go at least 137 once in a while lol, especially when the po po is on my tail haha jk....
this one guy reach 140 mph on a 1/4 mile. he has a video on youtube when he did it. I dont know his name on scionlife. if you could find him you should talk to him about it. here is the link to the video. He is driving the black tC. you just have to wait for him to show in the video.

Changing the limit without being tuned with an emanage sounds like that would be a bad decision to start with. Also - where the heck are you driving that people are passing you going that fast? ... ....that sounds like thats your first problem.
Jeze - Here in NJ the cops can either be very nice or total fools. I had a cop tell me he "thinks" I was going 85 in a 55 ..... which is 5points. Too bad I was able to get all the points dropped. 130 in a 55 you might get ripped out of the car with a gun to your head.

As far as I recall, at 130mph the car is already hiting 6,000 rpm, maybe a little more. You will not get much faster removing the limiter, since our redline is 6500 rpm. Find a way to add a 6th gear to your car, then it will be worth it.

if u travel a certain road for awhile you know where cops are and i have a certain point where i go early in the morning with 3 wide open lanes where its empty and i get up to 127 in a minute and its only at 4-5k that sucks....i hope nobody actually cruises at those speeds...when i was 16 i drove my 97 camry and it hit 125 and i got pulled over and only got a verbal warning
If someone reached that speed in 1/4 mile with a tC, they were about as stock as a race car. No way in HELL you would do it on a stock engine, even with massive amounts of boost. You are talking around a 10 second car to reach that or better.
And if people are passing you at 127 on public roads, you are both morons.

This car was at the SE Kick-Off at FIVEAxis the beginning of this year. It's been stripped down, and obviously there has been a little bit of work done to the engine.
