i run 2.1 and similar gears to you for far too long. mtdi was a big improvement in torque but riches etdi is really something else.

Must admit, I'm really excited!

When are you collecting yours?

next weekend.

Massivly overgeard with the 2.1... that dont help... Should work quite well with the ETDi I'd expect..

so, how accurate is the speedo?? it must be under reading quite a bit...

Still running a normal 543 box

Interesting, i only wondered as that's the exact mileage I'm getting out of mine. (M-Tdi with standard 5.43ratios, 235/75/R16)

Mine is 1ZMtdi
After a chat with Lee about the Etdi and injection advance benefits, I advanced up my timing and I now get 32mpg(from 28), lower EGT's, more power, and less smoke. Also, no unexplainable smoke when cold starting.
I think there is scope for further advancement
The fuel returns are when im making it work hard.
Ive never driven it to see what might be attainable
Has anyone got any mpg figures for their ETdi?

There's more than one conversation going on here...

DG on 4.86 diffs and 215/75/15 AT's works out to 60mph@3200 It won't do more than 65 on the flat
But why would you want to? That's when the mileage starts to fall off It still works fine on or off road though...

It is and isnt.. if the mileometer is under reading a good bit too then the mpg is skued too.. tall gearing wont help as lots more throttle needed.. the wbx would be well out of its comfort zone at that spead and revs... peak torque is where peak economy is...

The 185r14's on mine are too small.. they were ok with the prev engine (DG), but this one pulls loads better.. The speedo over reads, so indicated 100 kmh is really only a sat nav 90... the old DG used to like sitting at 3800-4000, spinning well in a part throttle.. the fresh engine, has a much wider torque spread.. and easily pulls 65mph (sat nav), loaded with a loaded trailer and still managed 19mpg on lpg on quite warm travelling days over 1400 miles...

Prett accurate from what I remember. Maybe 1 or 2mph under at the most.

Si, my speedo is reading 57 against 60 by the satnav. I know the distance of my regular run and how much fuel it takes to do it. Based on 2 runs per week since the first week of Sept I'm getting 26 mpg.
On steep hills it falls back to 2500/2600 (peak torque for DG as you know) and sits there

I think you've got the wrong speedo drive fitted

correct set up should overread speed by 10%, ie 55 indicated is 50 gps and the odomoter is bang on
if you run 205 speedo on a 185 van speedo will be within 5% but will underread distance and with 215/75/15 speedo is almost bob on but underreading distance (so mpg seems worse)

(runs out to van with a gobful of very late lunch)

1600 turn speedo, date stamped 2.86 on the back. No reason to doubt it's originality as the mot mileages stack up.

I think it's about right, under-reading by about 5% with the big tyres. BUt I don't know if it originally had 205's or 185's, short of doing the M-code thing

Yeah,.....but what speedo drive do you have fitted?

mis-read that! TBH I'm unlikely to get nicked for speeding in the old moose and I'm bored of grovelling under the thing until the spring comes!
I say that and the VC will probably go pop. It's pretty tight now!

Are we far enough off topic yet?

I think it is now....

I am getting about 26 mpg from my iz with longer gears and 235 70`s if its of interest

Must be doing something wrong if people are getting 35-40mpg
