Re: CRD engine chip

They also wouldnt usually inspect where the ECU is or anything and look for modifications. Hell my insurance company doesnt even asses the car, they just get quote from the smash repairs. Either way 90% of insurance companies cover modifications these days anyway. I know mine does, as long as its legal.

The only one you would need to have even a slight worry about is warranty, not insurance. And warranty claims you could easily remove the chip.

Re: CRD engine chip

Didn't I read somewhere that these cars have a black box style recorder in them? What data would it pull? Where does it get stored and who can access it? I would need proof that the "plug and play" was just that. Granted im no expert nor even electronically minded but it doesn't make sense that something taking such a big role in engine mgt and overriding the std computer can be so passive.

I would also need third party dyno reports proving its worth, when you get one please post the results.

I am not familiar with the Jeep system specifically but in general terms you're spot on. When I was in the cops I investigated a prang where a highway car had wrapped itself around a pole. The driver had claimed some mechanical failure had caused the accident and the union was jumping up and down because the airbag hadn't deployed. The black box (whatever it is actually called) had to be examined by the Ford engineers at the factory, but they could tell everything about the prang from speed, brake pressure, rpm through to newtons of force at impact, seatbelt tension etc. I would have no doubt analysis of this type of data would show whether something had been fitted at the time of the accident, particularly when the chip manufacturers claim significant increases in hp, torque etc.

My point is though.. even if you had a huge accident, the cops found you had a chip and all that, The chip isnt illegal, so it has no bareing on anything, and the majority of insurance companies cover legal modifications, which it is. So it makes no difference in an accident.

The only issue you may ever have, is if you put it in and it causes your engine to explode, and Jeep Warranty people decide they want to challenge it, and then they try and prove you had it installed and that it was purely responsible for the problems.

yes my point too. Surely Jeep can get info from the black box that might affect a warranty claim.

You are obliged to inform the insurance company of any modification, addition or subtraction to the vehicle i.e. fitting or removal of accessories etc. If you don't, the insurance company can reduce or refuse any claim. So as long as you have informed the Insurance Company and they have agreed and noted it on the policy, there is no issue from an insurance perspective. However, if you fit it and do not have it accepted and noted on the policy, you have failed in your duty of disclosure, giving the insurance company grounds to refuse your claim. Ditto with the warranty which states:

Your Warranty does not cover the costs of repairing damage or conditions caused directly or indirectly by any of the following:

Any changes made to your vehicle that do not comply with Chrysler specifications.

I would suggest the after-market chip would constitute a change to the vehicle and the use of the word "indirectly" gives Jeep a lot of wiggle room to avoid a claim.

Funny that, if it is so above board and benign to the motor, several of the posts are along the lines of "Just remove it if something happens and no-one will know".

I just can't see it being worthwhile when stacking up the extra cost, the minuscule potential gain in performance and/or economy and the potential downside, especially during the warranty period.

Re: CRD engine chip

My insurance you are not obliged to tell them, they automatically cover road worthy modifications (NRMA).

The performance gains of those chips is actually quite decent, up from 550 to 650 NM or torque, more power and better economy. Great for towing and long trips etc.
But they simply remap the air/fuel mixtures so for it to actually cause damage to the engine is quite hard and unlikely. Jeep would also have to prove the chip was responsible for the damage.

But the thing is it is the same as any modification. Same as if you raise you car, or if you put an exhaust on it, or change to bigger tyres etc etc, there is always a risk. If you wanna be 100% safe then dot modify your car in any possible way until warranty expires.

I can confirm that. My wife works for NRMA. You dont need to advise them of the mod if it is a legal one and does not affect roadworthiness of the vehicle. Any type of mod that needs engineering clearance must be notified.

You also need to notify if you want to increase value of the vehicle due to the mod.

Moderate chipping, in particularly on diesels, generally does not contravene standards roadworthiness.

Re: CRD engine chip

I run the racechip.de tuning box, and I'm very happy with it! perf/price is the bet you can find I think. I also use racechip.de on my past car, a Nissan NAVARA diesel (nissan frontier in USA). just happy with it and no problems at all for 100 000km...

Could you please write something more?

Sounds good. Can you let us know how it affected fuel economy? Do you have any before and after figures on that?
