Here in Oz, the 1HZ was fitted with a altitude sensor from 0ctober 2002.
Theoretically it adjusts the fuel due to external barometric or altitude pressure.
Anyone know where it gets its info from, and would it allow for a positive pressure (below sea level) in the inlet post turbo?
ECB are made just up the road from me, they export a hell of a lot of product, ok as an aluminium bar, but ya can't beat a good ARB steel winch bar..:)
