Hello you guys, I've got this thing with top speeds, you know, it's never enough!!

I have a 500+bhp twin turbo 350Z (I'm running it with a Haltech Platinum 350z PnP Engine Management) and it's fully tuned and working as a "proper" tuned car (no errors on ECU etc).
The problem is that nobody knows how can I get rid of that stupid 260km/h speed limiter I keep hitting...

 

IIRC shouldn't you be able to bypass the limiter with an aftermarket ECU?

 

500 hp @ .7 bar? wow, anyway the haltech should have taken care of that.

 

Good catch isn't that like 10lbs? He did say bhp though.

 

Yessir, about 10 1/3rd

 

haltech does nothing to the speed limiter. you have to get a stock ecu reflash to get rid of that.

(New data) power: 502 hp + torque: 62 kgr @ 12.5psi of boost...

 

all that money and the ECU can't do something about the speed...

At Nissan they said that they have to check it out... (meening they don't know what should they do!!)

Anyway, one guy I know has used the HKS Type III SLD Speed Limiter Cut Controllers. Any good? (the bloody thing costs $350 and all it does is delimit the car !!!!!!!!!!!!)
