Sounds similar to how they will cut your gonads off if they catch you.

European or Asian ECU is the only suggestion I have.

There is a guy named "Bader Al-Mane'a" in Riyadh who does ECU programming for this kind of stuff.

He removes speedometer limitations, disables day time running lights and he also converts F temperature to C'.

BTW, I had a friend who was tailing an '10 SS Camaro on a highway, my friend had the speed limit un-locked.

Don't know if he was telling truth or not. But the SS guy stopped him and asked him if he had any mods on his car, he didn't, he was driving an '05 bone stock LS430.
SS guy says he was going around ~170 mph, he had to open the road for the LS430 to come through.


Maybe it's just street talk, but the 3UZ-FE has got some life in yet no doubt.

Thank you

This topic has come up before on this exact sub-forum.

Here's the thread.

The prevailing opinion is that the best way to defeat the speed limiter is a new ECU.


HKS makes a speed limit defeater but I don't believe it has been tested on an American spec LS430

If you get a new ECU, it's worth checking out Tom's Tuning Computer T.E.C.II

Lexus governs the car top speed based on tire speed ratings as do most manufacturers. If you dogo higher make sure you mount the right speed rated tires

I road race an 06 Z06 and the most I've hit on a track is about 155. I've driven LS's for over 200k miles and there is no way I'd take one of these behemoths over 110. Different cars for different things.

on my Lexus tires the top speed is 181 MPH
i don't have any problem about that

But if there speed limit uni chip special for Lexus i want the link for it or how to fix it
