FORScan forum

Hi,

has anyone the same problem with an absolute speedlimit at 185km/h ???
I guess it is coming out of thre automatic gearbox.
I have set the speedlimit in the PCM to 254kmh but no chenge.

The PCM is starting to reducing Turbo presure at 160km/h so i bearly reach 185km/h
It is not RPM related cause in lower gears the Turbo presure stays stable till the end.

Forscan doesn't have the ability to change PCM software other than VIN & tire size.
You may get a few extra KPH if you program with the biggest wheel size it will accept
PCM will think your going slower than actual but your speedo will also be off

To change the tire size was also my idea, but to drive faster I need to make the tire smaller....

I will test it.
