re mapped diesel X Types and lowest current value
Discussion
anyone got a re-mapped diesel X Type near Northants, or perhaps lake district / yorks dales I could experience?
What is best economy you can get from 2 litre driven out of towns on 10 mile non motorway trips and also cruising on m ways - is this genuinely improved with a performance remap?
How much power increase (bhp and ftlbs) can be extracted from the 2 litre with low cost mods whilst keeping similar economy (increased on heavy boost and decreased on M way cruises off boost)
How cheaply can a 2 litre SE be picked up now via auction / private?

Can't tell you about saloons, but I've just had my SE estate re-mapped. Hp went from 126 to 150. Not sure of the torque readings, but there has been a tangible improvement. Fuel comsumption has increased from 38-39mpg to 42-43mpg around town. Have yet to try it out on a long run.
That must be a 2 litre then? - Be very interested in hearing your fuel readings for overall (not too much town or less than 3 mile runs) and best possible economy achievable on Mways cruising at speeds over 65mphMy 05 plate 2.0l x type estate is now averaging 44.8 to the gal, this is around town driving with no remapping done, so it will be interesting to hear to what extent the remapping affects the fuel economy,
tempted to come down to growler V1 in the x type dave, lol
but don't think it would go down too well parked amongst all the xk's

Andy, what's your average speed though. The trouble with my daily commute is that the traffic is invariably slow/stop-start. I can rarely get up to a resonable and constant speed.
Also the guys at Paramount said I won't feel the full effects for maybe a couple of hundred miles. With the increased torque my right foot has been getting heavier as well. The thing is I had a power remap and not an economy remap so I won't be seeing huge increases in mpg.
As for Growler VI I was thinking of getting both Jags there.

I had this engine in my mondeo and got similar performance increases when I had it chipped, and also similar economy gains, although my figures were probablly slightly lower, due to it being and auto.I never felt I got massive economy gains, but that was probably due to me making the most of the performance gains, as opposed to trying to eek out extra economy.
Once chipped, I thought the power and acceleration gains were marked, and the engine seemed to rev much more freely and right round to the red line.
Whenever I get a chance to do a long run I'll give you a shout Andy to tell you the results. As it is I am pleased with the remap, not because of the decreased consumption, but the marked increase in torque and power. I know she's still not the most powerful car around, but she does seem to be able to suprise some other drivers.
It would be interesting to comapare this remap and an economy remap.

Having a proper re-map is one thing - but most of the so called "chips" & tuning boxes work by making the ecu think that the rail fuel pressure is lower than it actually is. A side effect of this is that the fuel computer is also thrown out, reporting up to 10% more MPG than the car is really achieving. Beware!!
We had a customer who had 54mpg on his trip average, was 2.0D not 2.2D X Type, the 2.2 may be better.
He never went over 60mph in his life, I went out for a drive with him, he never got the turbo on boost either, gear changes at 2000rpm.
50mpg+ at 70mph+ is impossible. Unless you want a polo.

Hmm, quite a sacrifice switching to Golf / Polo? - for poss 12% better economy - had considered it... - fancy re-mapping a 2.0 d X type and perhaps fitting largest diameter combo of rims and profile 'Eco' tyres (unless you think changing 6th gear is practical and cheaper!) - Do you know any good mappers for this engine?He never went over 60mph in his life, I went out for a drive with him, he never got the turbo on boost either, gear changes at 2000rpm.

I take it you are a Jag Mech? - Fancy a winter project? - How about transplanting a used new style 3 litre Jag sport TDi into an XK, complete with matching auto box?! - Make a great tourer - I imagine cost would be prohibitive..
Another crazy thought off the cuff - can the 2.0d easily be 'stroked' using 2.2 crank or alternative custom to get 2.2 or more - could that be done with engine in situ? - And / or bigger / betterturbo + remap - looking for economic routes to enhance performance and economy of cheap used attractive Jags
Wouldlove a Coupeversion of X Type with flared arches similar to Steeds old S2 in Avengers (not so wild though) - using rear axle from 4wd and replacing / tuning engine is another option - new Jag 5 litre (non sc) with sprint geared LSD would be entertaining.........
