I think he's talking about the Navara, still not interested at this stage.

On a sort of tangent - you know how there are two versions of the VM Motari 3.0ltr v6 sold in Europe - 1 is just a detuned version.

The higher output engine comes at a premium, Do these chip boxes mean you can buy the cheaper set up and then just add a tuning box?

I know BMW and Mercedes (amongst others) sell detuned engines at discounted prices. Do these boxes spell the end for such practices?

Re: CRD engine chip

If the engine size specifications are the same, ie. stroke x bore, and the fuel input is also equal, then the most likely answer to the difference in performance is tuning.
I doubt whether these boxes would have an impact on factory detuned engines, as they probably also sell weaker drivetrains to go with such options.
The way I see it, is that these tuning boxes have their advantages in supplying more torque, which can be very useful for towing. It really is upto the driver to use that additional power wisely and not drive the car beyond it's mechanical limits.

Re: CRD engine chip

We are lucky as the CRD has a variable vane turbo. This means we just up the boost a little to get much better results. This is how the box can give you a 27% increase with just a tune. It was the same with my XR6 Turbo. We could get 300rwkw from a stock motor with just a tune and injectors. The stock motor was around 230rwkw, which is a massive improvement. To make the power reliable a bigger intercooler and fuel pump was recommend, but not essential.
I am happy with the power delivery since the last service, so I doubt I will get one, that and the boss will not let me tinker with her car....

No no, don 't want to advertise anything...

here is details, on the Navara...
4 cylinders turbo diesel, 175hp original. dynotuned at 225hp, racechip+ KN.





285/55R20 tires, and 2''lift

Before the race chip have tried the kitpower unit, that is 800 euros...result was good but too much smoke... then I tried a other tuning box from UK... didn't change anything on the car... then I have try this cheap racechip... and I was happy with the results...

video


I run this set up for 65 000km, no issue at all....

You can tune the box with 2 little potentiometer.. if you go too far, you smoke a lot of black fume... I did find the correct set up after 12 tries.

My wife and I just buy a brand new WK2 diesel 3.0 crd, original power 241 hp after 500km, I did plug the racechip box, 8000km now on the car and still happy with it, I did not find the time to try to find better result by touchin the potentiometer because power is now good enought... as it is my wife who drive the car daily...lol

Hope this helps...

Re: CRD engine chip

Any improvement in acceleration?
I'm asking because maybe I'll buy one.
200 euro isn't a high price for making diesel a little bit faster...


Beautiful pics BTW. Damn I love Switzerland!
We'll be staying one week in Lavaux this summer. Can't hardly wait...

Re: CRD engine chip

Will you be so kind and do a simple 0-100 time test? I'll be grateful.

Re: CRD engine chip

Heres an unchipped one - 8.5 sec




Edit - Here's an ML350...note the left foot brake to spool the turbo prior to "lift off!!"
