Thread: What could they have done to our fuel economy??

However, it seems to me that in view of the unusual data you are getting, you might need to fill the tank very carefully and note how much it takes to refill to exactly the same level to get some reliable data.

As long as you don't make the mistake of thinking that near enough is good enough each time you fill, that should give you accurate information, especially if you do it a few times.

Thank you, sound advice, and the same as the best the Service Centre could offer too, not having heard of anything similar. They didn't suggest hard resetting or anything. It does concern me that there might be a fueling problem given it's lack of mid-range punch, but some hard data will help.

Yes these computers aren't known for their amazing accuracy but they usually have a consistent bias (ie not accurate but reasonably precise?).

Hehe, sadly no... and really, what's the point if you can't mess with the solar system! :P

I wonder if it's too late to ask Santa for a BAS remap...

I wonder can that kind of thing be picked up by diagnostics?

Yes it can be,but i think it should bring up a fault code.
