i have an 2009 diesel x5 which i have a tuning box on, and i think it has made very little difference in power/torque. i was thinking of getting it mapped but the reason i went for a tuning box was so i could take it off before it went in for warenty/service work so the garage could not detect it. i was speaking to a guy the other day and he said that if i was to get it mapped there would be no way of the garage telling it was chipped.is this true?

 

yes

it wouldnt be a chip, we would flash a map via the diagnostic port, so theres no tamper markings either

 

cheers, have you done any?also what power/torque will it bring it up to its a 3.0twin turbo

 

chip seach here,

www.evolutonchips.co.uk

they respond very well, and fuel economy is up aswell

 

cheers

 

be careful bud we(vauxhall) can tell if the software has been changed in fact we are instructed to check now for warranty claims regarding engines/transmissions etc!although that is just on the vxr range that we have had to check atm!

Of course this is not to say its not worth while in terms of power and fuelling gains etc!jsut a view from a main dealers poitn of veiw!

 

+1 seems like main dealers are trying to crack down on this now quite hard or should i say the warrenty firms

 

how can they tell? can you actually see the file? was only a matter of time i suppose

because our maps dont flag checksum errors like most because we correct them

 

yes mate tell if the boost settings have changed/max rpm etc!although i will admit this particular only got caught as it had a strange trouble code stored!

 

this particular car was a month old and had less then 1000 miles come back with a blown gearbox!

found it chipped bye bye warranty!

no exchange gearbox avaliable as well!think the box alone was close to 3k

 

what if its remapped and goes in for work doing and it gets the remap wiped off by the dealers?
