I believe only the parts directly affected will be nullified, i.e. engine and transmission. Yes forensically it's traceable but unlikely in 99.9999% of cases they would even bother to look.

surely if theres a fault with the car first thing they will do is hook it up and see whats happening, they are easily spotted no matter how much you try and hide them but yes sometimes they have to dig quite deep to find evidence. obly affected parts will be void but it could turn into a right pitta if they stand firm on other bits.

The engine and running gear are the significant parts you really want covered in a worst case scenario.

It's not hard to detect a remap on a modern car. Plug it into the computer and it will flag up a code with many cars.

There has been cases where the dealer can no longer turn a blind eye to it either. They are forced to connect the car to the computer prior to a claim and can't hide it from the manufacturer.

Unable to read all the replies until tonight . Thanks all for your advice and opinions it's much appreciated

Most maps are undetectable, even if there isn't an issue every time there is a software update when you take it in for a service it is usually wiped. Becomes a bit pointless and too much faff on a new car

Tell that to the guy that was in audi service next to me (a couple of years back now) and had his warantee claim refused because the found out that he was using one of those BlueFin self flash ecu remap tools.

He had put the standard map back on prior to taking the car back in thinking he would be OK. They found out!

Please.... c'mon if they want to find it they can they just have to dig really deep sometimes but theres so many signs of a map having been present, all the flashing and removing battery stuff doesnt work. Just have to ask yourself if its worth the risk and hassle.

I guess it depends who's done it and how they do it. I know quite a few people with maps and they have maintained warranty; mostly benz's though

If the map that's downloaded to the ecu is named the same as the file (map) that was previously on there how can a technician tell unless he opens the new map and compares the figures with an original map?
That takes time, effort and appropriate map reader. Which I assume the obdi diagnostic tool in an average dealer workshop is not? Just my thoughts.

Dtuk best option well happy with mine

you would be surprised how easy it is to detect a map/increased boost pressures/ max speed/revs at time of failure. I work for a main dealer and the first thing they ask for is a snap shot of the ecu along with the "secret menu" which contains the above data. takes about 5 mins to get it

130 Bhp in a modern car is probably fairy decent. I remember my first car being a 1.2 fiat punto with 60bhp. Not a bad first car but very slow. I've had many cars since and now gone back to an eco box. I've now got a newish 1.0 Up! With 60bhp but the response no torque in the up! Makes it a far nippier then the puntonever was. Only way is to try it. 0-60 generally a good indication too.
