why? 120mph is more than enough ...

 

Not on the autobahn. 120 is fine here in the USA, but not in Germany.

 

It can only be done at a dealership. Considering he's in Germany and the car is US, I dont think it can be done with Germany tools. Purchasing such a diagnostic device to change things will cost a pretty penny and probably hard to obtain.

 

You might be able to use a speed cut defender. HKS and Pivot make them, among other brands, which removes the speed cut by tricking the ECU into thinking that you're doing less than the maximum speed allowed by the cars factory speed limiter. It would typically be installed by splicing the vehicles speed sensor wire that leads to the ECU.

 

Cool thanks for the tip ill look that up! I saw a bunch of devices that look like they connect to the service point and then have some override function to unblock the speed limiter. But I don't know if I was looking at the right model for the Camry or not or if there even was one for the Camry...

 

There is likely a REASON that Toyota put a speed governor on that car and it probably has nothing at all to do with the speed limit in West Texas or Nevada. Have the engine pulled, disassembled, and blueprinted before it ships. Get it balanced like a NASCAR engine. Then it might last. Otherwise, drive in the right lane and be happy with it.

 

^^ agreed!

I had an '02 Camry until about 3 months ago (bought new in 2002). I can't imagine doing 120mph in that car let alone any faster. First thing that comes to mind, what kind of tires does your cousin have on that car?

 

Is it a V6 or a 4cyl? If it's a 4cyl I'd say there's not much point in defeating the speed limiter because I doubt the car could even break 135-140. Also, don't plan on the car lasting very long driving like that either. If you're looking for speed, I'd say just sell the car for something faster. The Camry was designed to be a comfortable, economical daily commuter, not a BMW-killer.

 

Toyota production engines are not designed for that kind of driving and that 2002 won't last very long. Heed the advice posted above and take the secondary roads.

 

I don't know, I'm pretty sure a 120mph cruise is only around 3-3.5k RPM with a V6.

 

Well, the speed red line of 120 would apply to an I4. The V6's are set a little higher, but as for the cousin working in a repair shop, well, that must make things just all right then.....

I'm guessing you have never seen a German highway? Yes the speed limit is higher than in San Francisco but guess what? When it rains, people slow down because they don't want to die young. When it snows, the same, and when someone is driving a smallish car with a top speed of 120 km/h, well, that's all they do. Tell your cousin to drive a normal/safe speed and finish job in good health.

 

I agree with this... a 4 banger shouldn't try to do more than 120mph. Are these cars even equipped with powerful enough brakes?

 

Sigh...

 

Ok so I told my cousin all the things you guys have pointed out on here and this is what he says. Apparently on the car, when you touch 120, the fuel injection stops and so the car dies for a bit and slows down and then accelerates and dies and so on and so on... So he can't even do a steady 120 on it. Also he said that he knows the car wouldn't be able to do much more than 15-20mph extra with the limiter off, but the little extra would be nice especially if it does not keep dying and coming back to life when he touches that speed.
So if you guys can help with unblocking the speed limiter, any help would be appreciated. If I want opinions on weather I should do it or not, I will open another thread. But thanks for the concern

 

Ok so here is something that I have found.

http://www.yourhotcar.com/prod/Gred...rogrammers/Toyota_Greddy_Speed_Limiter_Cut_Controller_Type_A_-_15590201/803526/

So does anyone know if this is compatible with the 2002 Camry 4cyl? And apparently the ECU has tons of wires in there. Anyone know how to find the right wire and which one the right wire is?
Thanks!

 

Before defeating the ECU control, make sure you do appropriate upgrades to the wheels and tires - the 'normal' tire combo was "T" or "H" rated. Sustained speeds over 120 will kill both. "W" or "Z" tires with appropriate pressure adjustments are mandatory, as are upgrades to brakes. Stock Camry brakes of that vintage will be hard-pressed to give more than 1 stop from that speed.

 

So I assume nobody here really knows how to do this huh...

 

Exactly right. The speed limitation is built into the computer and there isn't anyone here with the technical tools and skills to hack the computer, decompile the information, determine which byte determines the maximum speed, and make the change. It isn't safe to drive the car at that speed anyway unless you are on a closed circuit, so the motivation is pretty limited. Have your cousin leave the car on this side of the Atlantic and buy another when he gets there. Solves problems.

 

the car is already in Germany. It's been there 2 years now. Anyway forget it, I'll ask for help elsewhere. Thanks everyone.

 

Take it to a speed shop over there that specializes in ECU modification for import cars and they will explain the terms to you as to what's required.

Even if you get it done, I wouldn't expect much of a difference out of a 4-cylinder Camry which is going to be limited more by it's power or lack thereof.

 

Most all of you guys are wrong...sorry.

The Camry 4 cylinder can easily do over 120MPH, and its not stressing it AT ALL, or over revving it. Get real, how many RPM do you think its doing at 120, if at 60MPH its doing only 2000 some..:headbang:

The reason for the speed limiter is ALL for legal issues. The tires, cars aerodynamics and ALSO the rotational speed of the half shafts, are what determines top speed safely in all cars. The camry is fine aerodynamically to do approx 140 some MPH easily. The engine is fine to do that speed, the tires are not of course.

I lived in germany for years and a german spec version is not limited and will do much higher speeds. I forget exactly how fast but in the ball park of 135-140 I believe. The camry is VERY low coefficient of drag and with 158 hp it can really get up there.

 

that looks like it will do the trick... honestly if you cousin works at a repair shop then someone there should know how to install this.. get the diagram for the ecu and make it happen captain..

 

ECU swap to German one.

 

You guys bored? Thread is over 5 years dead.

 

And the OP apparently has not posted on here since. Must not have appreciated all the "don't do it!"s he received. I'd be white knuckle driving pushing the Camry over 120. My '09 SE pegs out at 140 and I'm like "Really?" There is nothing going on in my life pushing me to approach those speeds
