PostPosted: Thu Mar 13, 2008 12:25 pm 
HI, does anyone have any experience of chipping diesels? I've recently bought a 2.0 diesel automatic and am looking to boost my economy and thi sseems like a 'fun' way to do it.
I've been looking at 1 from a company called Tunit, this is alink to a reprinted test of a chipped Quahqai which uses the same engine http://www.tunit.com/resource/press_rel ... ashqai.pdf
Any thoughts would be appreciated, thanks

Hi ajp
I have no experience of chipping, but I would advise you to check with your insurance company before going ahead.

Hi apj,

My 2.2Dci is "chipped", I had a few problems in the first instance, If you have it set up for maximum performance it tends to put the car into limp mode if you accelerate hard. It does make a difference even on a slightly steadier setting, it gets rid of the flat spot at 4000rpm, economy seems better, and it make for a more smiley experience all round. I don't know about tuning the 2.0, but just be aware you may not get all that is promised. I also opted for a K&N air Filter.

Hope this helps

Hi,
Anyone have any more information on this issue.
There are lots of companies offering diesel chips now and claiming increases in power and economy.
Prices around £400 which they say are simple to fit or they will come and fit them for you FOC.

Location: Acle, Norfolk
Car:: Xtrail
Model: Aventura Explorer Extreme 173Dci
Year/Plate: 2008
Colour: Blue
Mods: Tow hitch, Vredestein 235/55R17 Quadrac ExtremeTyres
I chipped a Jeep Cherokee a couple of years ago, the results were impressive. The car was much quicker, mid-range acceleration was brilliant, and fuel consumption was improved by 4 mpg. As for insurance, I told my insurers I needed more torque to tow my caravan, they said OK, made a note and didn't up my premium.
I'll see how my 173 Dci tows, if necessary 200bhp beckons!
If you fancy it do it, but don't tell the wife. They don't seem to understand us boys and our toys.
Hope this helps.

Stay clear of any clip on device as they only fool your engine into thinking its bigger.
The way forward is to have a professional remap your engine the costs are between £300-400 depending on who does it.
All older (pre t31 models) come from the Manufacturer as 40% efficient so there is plenty of tolerance in the engine, a stage 1 remap will improve your engines efficiency by 20% boosting a typical 2.2 DCI to around 160-165 bhp and around 278 lbs of torque.
I have a TD5 Disco which I had remaped and the improvement is very noticable, also as you have more torque at your diposal there is no need to drop down gears (when towing up hills) therefore increasing the fuel economy. My remap was done 2 yrs ago and the reliabily is second to none.
My advice would be to get your X Trail remaped NOT CHIPED, you wont regret it.
PS if you then drive it like a boy racer it will cost you more in fuel.
