Well it looks a little better, not having to rev as high and change gears as often maybe. But then again I wouldn't like to say that the figures reported by the car aren't actually skewed (ie optimistic) in some way by using the Powerjet unit. It seems form reading the posts about remaps (diesel) that real life fuel economy is basically unaffected. Not having to drive as hard (less fuel consumption) is offset by more enthusiastic driving?
I have logged into Fuelly and will report the MPG when I get some useful figures.
So a bit of an update.
The only problem I have experienced since putting the box in is that the urge to keep it in gear that little bit longer, to accelerate that little faster is very difficult to resist. Nothing crazy, I can't abide people who drive like complete ar$es. But anyway, one of the main consequenses is that the mpg takes a bit of a hit shall we say...
But over the last couple of weeks I thought I'd see what it would be like if I kept things a bit more under control.
So, after the following trips.
1 Bishop's Stortord to Ealing
2 Bishop's Stortord to Kensington (across town)
3 a week's worth of local trips
4 Bishop's Stortord to Bluewater then on to Staplehurst in Kent
The MPG reading is 32.1 this morning.
Around town I have been driving "nornally" and resisting the urge
On the motorways I was driving 70-80, so just going with the flow of the traffic but not dawdling.
I had never really been able to get it to stay above 30mpg if any kind of toewn driving was involved. After driving through London twice I'm quite I would definitely be struggling to hit even the mid 20's previously. The reading may be wrong because of the box and all that, but it certainly fells a little less thirsty on the longer drives.
Fuelly had been telling me that I was in the low to mid 20's before, which was in sync with what I was reading in the car. That was for abotu 90% town driving, hardly an long distance driving. I've got to admit that I haven't kept Fuelly up-to-date, bti too much of a pita....
So, all in all not too bad.
