Hi Paul That model 30D is not a very common xf most were sold as company cars for junior executives.

£395 for a tuning box is a rip-off price! For something which will just change the fuelling as the parameters inside the ECU will still be factory standard and will probably end up messing the particle filters.

Best have the ECU remapped by someone like Quantum Tuning  who will remove the ECU and open the box and rewrite a map and change parameters to suite your requirement? There agents will do at you home address by removing your ECU and send the factory map to there HQ and a safe tuning remap is sent by return and installed. For less cost than a tuning?Box.  

I had no idea that the fueling is all it changes. I thought something along the lines of the box essentially being the ecu or overpowering the ecu :D

So it could mess up the particle filters, any other problems it could cause?

these types of tuning for diesels is super common, if it could potentially be quite bad for the car then surely there would be lots of reports saying dont use them right?

I just connected a chipmydiesel remapping box to my S Portfolio. First week my avg fuel consumption dropped from 8.1 l/100km to 7.2. Not bad considering the extra torque and power I now have too.

Thats pretty impressive! I wouldnt mind having less fuel consumption with increased power and torque. :)

ps, totally forgot about the thread :D

Hi Dave,

thats interesting, thanks for letting me know

ill research some more. Ill post my results

cheers

Paul

thanks for your reply

thats interesting you say that, obviousy the numbers are optimistic but that much I didnt expect.

What do you mean with bigger breaks? I wasnt going to change those, I was only looking at the chip.

The S might have been fited with bigger disks as standard and the gearbox maybe slight software enhancements but Im pretty sure there is no difference otherwise

Greetings everyone,

I have a 3.0L executive edition (the one with 211hp) and I am interested in the engine upgrade from Chipexpress (this one: http://www.chipexpress.com/products/2790/)

It seems promising, it gives my version the same power the Diesel S gets delivered with. My research tells me that the engines are identical for all three power versions and the only difference is the software, is that correct?

next thing does anyone have experience with this exact upgrade?

are there any problems asociated with it?

can you install it without my dealer ever knowing (warranty seals?)?

Any information would be greatly appreciated

cheers
