I'm booked to do a charity rally from St Austell to Pompeii, and back, in September.
A friend of my wife has given me an 'X' Reg E Class Estate 320CDi, it has a complete MB service history with 181000 on the clock.
(Straight 6 engine)
On a run cruising at 75/80 mph it is returning about 44mpg - which I thought was very good for such a big engine.
I see from this forum that you guys are modifing maps to increase power etc, is it possible to edit a map to give better economy?
The rally will involve driving about 5000 miles over 7 days so its quite intense and even a slight increase in fuel ecomony will make a big cost difference.
Anyone able to help, or is it even possible?
PS I have mpps, not sure how to connect to 38 pin diag port thou!
