Remap and Chip same thing the ecu .bin files get edited and loaded back to the ecu, The the method of how the software get to the ecu differs, a remap is like uploading picture from your iphone to your pc its all done via leads and software, chip tuning is more like having a film negitive developed, some one has to open the ecu unsolder the chip read the chip, and in most cases have to insert an new flash type chip or a PCB protection board... which leave physical evidence of the software being changed.
Remapping won't void your warranty!
ecu remapping
How do they sleep at night?....

Its the usual sales Bull crap... as bad as the quote "our maps are TUV tested"
So what they are saying if a modern petrol turbo map which is set to run lambda 1 has the boost wound up from a remap and it melts a piston or valve the dealers have cannot void the warranty due to EU PC BS..

? All they have to do is fix the car then use diagnostics software to log the ecu, lambda and boost values to see its running lean, then void the warranty.
My mate Craig owns the local Fiat dealership. He had in a punto abarth which had 27 flash counter readings and a melted engine with less then 2000 miles, and after they fitted a new engine they logged the boost and fuel only to it was far too lean which back up the 27 flash counter reading, in the end the customer ended up paying £7,000 plus £600 for an new ecu as they said the could not get the map off..

The customer said he left the car at a secure car park at Gatwick for a week, and while he was away he said the valet parkers must have the car to a local tuner. I have mapped a few Punto Abarths now and all have been fine and still are valid for warranty at my local dealer.
But if your with JRtuning It seems they will fix the car upto the value of £2,000,000 if the dealer refuses to fix the car? IMO if this is true its a win win situation, for for the members who is worried about warranty should forget all the other tuners and head to JR... (Oh look I can do sarcasm..lol)
Truth is remapping is a gamble/risk, Even with the best tuned file in the world, the car could blow up straight away after a remap but whats to say I was not about to fail on the stock map?
