Does anyone has an experience with diesel chiptuning box like this or similar?

Thank you!

I bought a RaceChip tuningbox a year ago. It did improve torque an Hp and went well for 10.000 km but then the DPF started to fail. It cost me around 1000 Euro to get that fixed. I removed the box after that.

If you have DPF on your car, and I believe you do as you're in the EU, don't put a tuningbox on your car. Get a remap of the ecu, that's the only right way to tune the engine.

Thank you for your answer!

Does the   remaping  of the ecu  brings
reduce of consuption as well?

I am no great fan of re-mapping a standard car. If discovered during a warranty claim you are stuffed. Not only that, remapping is not cheap. Even even though it may - and I say may - improve economy - it would have to be my a significant amount for you recover the cost in fuel saving.

If you are dead set on it - do the maths first.
For example I do about 12000 miles per year. The car averages 57 mpg and diesel costs approx. £6.30 per gallon. Annual fuel cost £1,326.

If I plan to keep the car 3 years then total fuel cost for 36,000 miles would be £4000.

If a remap improved economy by 5% then fuel saving would be £200. If 2.5% the saving would be £100

My friend has paid £360 for a remap to his Seat Leon and he reckons he gets more power AND his economy is 3% better. He averages only 10,000 miles per year. Frankly, I would not take the risk of a warranty problem for so little benefit.

Yes, but don't have the remap done because of the savings. If you want better economy just drive more carefull 

i have several colleagues who have had various cars remapped. All of them say the economy have improved as well as more power.

I didn't get any fuel saving with the tuningsbox fitted, and I did drive carefull, as those 10000 km was in the winter.

A major car manufacturer has a deeper pocket and far more technical resources than a small tuning company could ever have.

Ask yourself - if it is so easy to alter the ECU mapping to get better economy and more power - why doesn't the manufacturer do it?

 After all - they are in a viciously competitive world market and could enhance their car sales if their cars out-performed the competition for so little extra cost.

So once again I pose the question - if remapping is all it is cracked up to be - why doesn't the car manufacturer do it on the production line?

Who could possibly resist buying an i30 Tourer (CW) with a 1 litre turbo engine providing a top speed of 140 mph, 0 to 62 mph in 6 seconds and economy of 84 mpg at a lower price than its Ford, General Motors, Honda, Toyota or VW Group rivals.

You could be right, Alan but if I have to chose between remap and a tuningbox, I definitely believe the remap is the better choice.

The tuningbox "cheats" the ecu with false signals, the remap alters all settings in the ecu.

Probably because the manufacturer has a warranty to consider, and therefore needs to have an ECU that can be used across an entire production run safely, so as to not cause engines to wear prematurely, or worse.

Depending on the ECU remap, you could potentially see earlier engine damage as components are put through higher stresses than they are capable of withstanding. Particularly the common rail on diesels.

That isn't to say it (failure of part/s) will absolutely happen, but that there is a higher chance of it happening when you start putting the engine through stresses it/individual parts may not be able to deal with.

I've contemplated an ECU remap. But would only ever do it after my warranty ran out, and only after getting the car dyno'd first to see what it's performance was like to start with. I would also want to know I could return to factory ECU easily enough.
I actually think with some tweaking, the 2013 i30 could get close to 120kW and 320ish nm of torque, as well as address the bit of turbo lag sub 1200rpm.

i had a friend use a tuning box on a diesel, long before i owned my first i30, he was using it on a VW 1.9 TDI it was adjustable & he had a novel way of testing it, but said it blew more smoke out the pipe. he hooked up a trailer loaded, towed it up same hill, would use his GPS speed recorder to register the speed he reached up the hill. he would make an adjustment then test it up the hill again to see what setting got the car to highest speed up the hill towing the trailer. not the safest way of doing it but works like using a dyno to test what setting worked best. latter he took it to a dyno. i don't know why he went to all the trouble but was interesting to find out his findings he was in USA.

myself if the car does not go or perform as well as i want or need, i would think i got the wrong car. so sell & look for something that does what i want. but living in Australia with enforced maximum speeds that are slow. you don't need that much power but you need torque to climb hill's & overtake quickly. the i30 not a performance machine but it  does the job for me. & has not let me down yet ( 2 in past 5 years ) so happy.
my view is to make map's, it takes a good operator that does not mind spending a lot of time on a dyno testing & making adjustments . they do it if they think they can make $, but one does not fit all, they would have to make a map for the i30. i think there would not be a big enough market, so they might just use a map they made for a similar diesel. i don't think thats ideal. but just how i see it.
