any body know how i can get rid of this permanently or temporarily.the reason is the next day at elvington is also a top speed day as well as a 1/4 mile.and i have a funny feeling 155mph just aint gonna be enough.on my private test track(m1) it will hit this limiter in fourth gear still pulling like a train,and that is off gas and before it even gets into fifth.
i have tried superchips and they suggested a place called autologix(autologics?) in buckinghamshire,but i cant find anything about them.i have tried bmw forums and no one is any the wiser.the trouble is i think iy works off the speedo and not true speed as when it hits 155 on the clock its actually doing 143
