Title: Tractor MPG
Post by: TheBoy on 06 March 2009, 08:45:18
After getting a feel for Tractor economy, just to see if mine has something fundamentally wrong, or if they are all just crap.  Just trying to work out if its worth spending any more time and effort on it.

Only interested in 2.5TD engines here.

Hmm thinking outside the box here,
does the mid  get information from the maf? cos im guessing it does,
so Im thinking if the hotwire is slighty dirty or old it would give a slightly wrong signal? so basically what im saying is have you tried another maf????

Sounds about right Jame!
Since you and Mark chipped my manual-boxed estate, it's returning 33mpg constantly. Taking into account the Valleys terrain and 'reasonably spirited' driving style I'm pretty well satisfied.
Still, I'd be even happier with more MPG - but wouldn't we all!

Valleys terrain ?!?  Most of your patch is more like the Alps.  ;D

33mpg from a tractor is rubbish, take into account petrol is almost 10p a liter more at the pumps, you might as well run a V6  :-/

I get 40 to 41mpg on a mixture of town and my daily A road commute and 50-51mpg on steady run, sticking to 60-65mph.

gets from engine ecu.  remember the mid is accurate with the std chip in.  I think i know why mid inaccurate with performance chip in

Mine I would say is much the same as your's, mine is chipped also.
Pre chip I regularly got around 29mpg just local short stop start driving. Longer journeys would return around 42mpg pre chip.
Yes the MID display is wayward with the figures after the chip is installed, especially the range "miles left in tank" readings which seem to be all over the place..........Having said all this would I take the chip out................No!....... rather have the performance at the expense of economy.

In my opinion the chip transforms the performance of the TD and it was supposed to give me better MPG as well (so the guy who supplied it says) but hey I'm not complaining for the money it cost me. Really comes into it's own towing the caravan (no jokes please) more power  even if the MPG suffers. It used to be really scary towing before the chip was fitted, especially pulling away from a standing start......gutless.

Obviously I can't speak about towing, but I seem to get a good 10% plus improvement on economy with the chip, even though I drive it in a more spirited manner.  So purely from that view, the chip is staying, as its more economical and more power.

My trouble is, when the old head was on, I used to consistently get (according to MID, and pre chipped) 37mpg.  Hence why I've been chasing potential problems with fuelling of the car for the last year or so.

I am beginning to wonder if this was purely down to the fact with the old, damaged head, I used to cruise everywhere gently - give it any large anywhere for more than 10s and it used to blow its load all over the carriageway.

Dead right - I went back to the standard chip for 3 weeks in Jan/Feb, and its horrible. Awful. Undrivable.

Okay 'Alpine' terrain it is then - but much more testing than in your 'Sospan' and 'Jack' areas .... !!!

We sing from the same hymn sheet Mick! - though I haven't tried towing our caravan since it's been chipped.
