Hi, I am new to the fourm. I have a mazda 6s 3.0L, my ? is it cut out at 120mph so how do I turn off the speed limeter? [&:]

 

You don't without bypassing the computer.

 

where can i get a computer? I would like to see how much more speed my stock v6 has befor I stare the upgrads!!!!

thanks [&:]

 

It's not that easy (or cheap)....You would need to create your own fuel map to run the engine to run the standalone computer. To do this right, you need ready access to a dyno ($$$$) to tune/tweak the fuel mapping for ideal.

I'd say top end on a stock Mazda6 beyond the speed limiter is in the 140-145 mph range.

 

Thanks again for the info. so I willn't get to go pass 120mph.

 

My 2007 Mazda 6 barely makes 110 mph, then starts gasping for air. There is a speed limiter( I asked my gear head mazda mechanic)
Some one must know how to swap out chips or overide this feature. I plan on adding a cold air intake and a decent catback exhaust,if I can ever find one. Got that need for speed!

 

email the guys over at Unichip. though i have yet to get confirmation from the people that have it on the car, but i believe they say it will remove the gov. so for like $750 or so you'd get a bit of gains as well as remove the gov.

 

I have no prob. hitting 120 in 4th gear, then the nose drops and my back comes off the seat when the car stops pulling. After all that it will sputter from 119 to 120 cutting in and out!!! I want to go faster in the car! I do have a weekend ride GSX1000 that will do 160mhp.

 

The uk model is unristricted and from personal experience i wouldnt take the car over 130 anyway the stearing gets very light and the front end starts to lift

 

i'd guess most people looking to surpass the gov. are those that mod tha car as well. i've had mine up to 145 and didn't have any drivabilty issues whatsoever.
