What it does is, it limits acceleration when pulling away, limits the amount of kickdown a driver can use and the top speed is also limited. The main problem is when it reaches the top speed (which on most is 53mph) if you push beyond the limited it will let you for about 3 seconds then drops the speed back to 45mph.
Mercedes/Daimler designed this program so as you can imagine it works as designed on Mercedes products most solos are fitted with it. On VDL products it just doesn't work which is why passengers feel the difference between one that's fitted with it and one that's not.
Any more questions PM me.
Some of those Pulsars didn't half go, pre-econospeed. When it was first fitted, you could tell the difference between a Darlo and Durham pulsar, pretty quickly - though at least a couple of belmont's were already knackered and sluggish, anyhow.
