Okay, so these devices are supposed to cut the factory speed limit at 127mph, does anybody know if this works for sure?

I have the e-Manage Ultimate on my car and it runs to speeds above 140MPH now.

i have the apexi rsm and it is supposed to cut the speed limiter off but i havent had a chance to go over 100 and i wont do it unless i can get to a nice track but the only close on to me is the auto bahn coutry club and that place is expencive lol but i would love to test it out

 

Where did u get your RSM and for how much?

 

i got it used for 165 from a forum member who sold his turbo integra and he pulled it off of ther for me

im trying to sell it right now for around $120 so i can fix xome crap on my car

 

emanage comes with a rev limiter from what the description says...

thats great to eliminate the governer but rev limiter is also a must have with it...

is there any other products that has a rev limiter in it???

 

Since I hate when people start new threads about old stuff, I found this thread by searching, but it seems a bit incomplete.

I doubt the HKS device works on a tC, I know what those things do, and I'd be surprised if it actually worked on a tC.

The eManage option appears to remove the top speed limiter, but also adds a bunch of other stuff that I won't necessarily have a use to do.

Does anyone offer an ECM mod to remove the top speed limiter?

 

Why would you want to get rid of the speed limiter?? In the case of any Scion for that matter

Are you planning on hitting 160mph constantly that you will need it?

 

127 isn't very fast, and yes, I run without the TRAC fuse in my Supra because I don't want to be limited to 155.

 

And your going above 155 daily??


I guess a person buys these for the "coolness" and "yo bro JDM man" factor
Not nessarily for what its used for...which is high speed road coarses where high powered race cars are constantly making it way passed were the speed limiter would be because they have the HP to get them there

 

I don't want to buy anything. I want to reflash my ECM and get rid of the top speed limiter.

Let's see, I can predict where this is going now. Why do you need to do this? I don't NEED to do this, I WANT to do this.

Isn't 127 fast enough when the speed limit is 75 mph? No, IMO, there should not be an arbitrary restriction on top speed. If there is a reason for it, such as, the front bumper is not mounted strongly enough to drive at sustained speeds over 127(and if you've checked your front bumper, you just might wonder this), then fine, I will accept it as a design limitation.

Do you NEED to go faster than 127 everyday? Of course not. I'm not brushing my teeth here, I'm just changing a limitation imposed by the manufacturer.

BUT, what gives you the right to tell me what's good for me? By your logic, we should have speed limters installed on all vehicles to prevent driving over the 75 mph nationally accepted maximum speed (except in Montana). We should be happy with our 160hp, or actually even less because we certainly don't NEED 160 hp to go 75 mph. If my numbers are right, we should only need something between 15 and 20 hp to cruise at 75, so what in God's name are we doing with all that excess capacity besides burning fossil fuels into complete global extinction?

I've heard all these arguments many times at many thresholds for both cars and motorcycles. Here's a great one, "Who needs a motorcycle capable of running 9 second 1/4 miles in completely street legal trim?" Why, no one NEEDS it. Can you buy one? You bet. And guess what, there's more than one manufacturer doing it now.

So, does anyone know if it is possible to reflash the ECM to remove the top speed limiter?

 

Can it will ya?

 

Awww did I hurt your feelings by asking such a question? poor thing

 

Yeah Im really sensitive ok? Please no more harsh questions

 

hmmm...I did't realize that the tC was goverened. I thought that 127mph was the limit due to drag. Learn somethin' everyday I guess. So in theory, thc stock tC (ungoverned) will do ~140mph flat out?

 

no the tc will not do over 140 it doesnt have the power or the proper gearing


TurboCustomz goes over 140 becosue he runs a shot of nitrous and a modified zpi stage one lol his car is zpi's car so you know it is a monster im sure over 400hp with the nitrous but ill let him tell you about his car

 

The Emanage Ultimate can and does get rid of the top speed limiter. With the
Ultimate you can also raise therev limiter. This is not to say that you do not have one but you can raise it higher to meet your needs. This is a great addition to our head package or whatever your needs may be.

The thing that you need to realize is that it may take awhile to get to 127 now. But with a 16G on the front of that tC it happens much quicker. When you are rolling up that C5 and all of suden you can't go any faster it sucks.

Are you sure the tC cant go over 140? Can it get to at least 140 stock with the governor removed because when I hit the limiter it seemed like it still had quite a ways to go and it reached 127 pretty fast.

 

Of course you hurt my feelings. That's why your argument got squashed with all your anticipated arguments in one post instead of wasting five or six iterations of you asking increasingly stupid questions.

I think I'll go endanger the general public by driving my Supra 170 mph like I do everyday.

 

For the ECU speed cut... You need to find the speed sensor going into the ECU. This has proven to be hard because it all goes into a secondary ECU for the EBFD. Only mixed signals hit the ECU from what I remember. BUT, if you can figure out which signal hits the ECU, you'd only have to put a voltage clamp on it at the desired speed. It's hard to know the voltage though at 120 persay, so who knows what to clamp it at. The Apexi RSM though is a smart unti. The problem with voltage clamping is that your speedo will also show only what the ECU sees, so even if you clamp at 120, your speedo never passes 120 as you accelerate. If you use the Apexi RSM (built in variable voltage clamp), your speedo stops working at the desired clamp voltage, but the built-in speedo on the RSM keeps on going showing you what you're actually doing. It also holds the peak value, so focus on your highspeed run, and then look back at it later.

I haven't have time to find the speed wire on the ECU, only the one on the center console. I have the RSM and use it more for suspension tuning than anything (G-SENSOR). It is a capable unit though, not bad for the price.
