Hi everybody,
I have a Mazda rx8 2004 model I imported it from Japan.
One day on the motorway I wanted to check the top speed of the car i took it in 5th gear (its a fivespeed) and it wouldn't go any further than 187kph.
It seems like it is limited at 187kph.
Does anyone know how you can remove the limit because the rx8 should go up to 250kph if im not wrong.
PLEASE HELP!!!!

You probably need to find a tuner to reprogram your ECU.

Winning 8

you only have a four port motor, and in japan all car has speed limiter.

shawns

Yes so how can i remove the limiter?

shawns

where can i find that?

All Japanese car has speed limiter.

4-port MT should go 230 KM/H max.



HKS and RE Amemiya have a picky back unit to do it
Knight Sport can re-flash and unlock from ECU.

MazdaManiac mentioned that COBB Access Port also can do that too.
I PMed him for confirmation but he did not reply.

Really?
Need vid, wanna see.

shawns

Yes if you could make a vid about how you do it,that would be great!

shawns

It ain't cheap. But it will get the job done.

One drawback is it might intervene with traction control.
I'm not sure if new version solve this problem or not.

shawns

That's really annoying because rx8 is a sports car so it should at least do 230kph/h

Yeh but thank you

padilla08

anyone heard of the jdm version of e-manage doing the trick?

you can actualy slightly press the clutch in and it will keep pulling past that.

but yeah, I say get the hks. Should be about 100 bucks.

bencwloon

have any internet link can order the SLD ?pls PM me thanks all

padilla08

the SLD takes off the DSC once you get past the 187 mark. won't you need it, especially in high speeds?

padilla08

isn't the price WAY too steep just for one function?

can't the E-Manage Ultimate take the limiter off? or maybe even the Unichip?

sld Z3 is about 270 euro in UK

check this out: http://cgi.ebay.co.uk/HKS-Speed-Limi...item43957e9d77

if you can pay 500 euro is better to purchase an access port from mazdamaniac and he can remove the speed limiter + you tune your rx8 for better performance and reliability.
