So I decided to get my A3 2.0 Tfsi remapped after reading up on how well it unleases the cars true potential. Not having any major tuning companies near me I decided to go for bluefin superchips who provide you with a handset so you can map the car yourself. So when the handset arrived it was pretty much follow the instructions, plug in the device to car, upload map to laptop, they then recieve the map and send you their edited one back, you plug that in and off you go, 5 hours later. After connecting up the bluefin and installing the remap I was ready to test it. I started up the car and it made a lot of weird noises, knocks and thumping that went away after 10-15 seconds. I straight away messaged bluefin to ask if that was normal, and they replied it was diesel knock - a hangover from OBD communications whilst it syncs to the canbus. Great so my car is a diesel?! After telling them that it was a petrol, they said the same thing and not to worry. Time to take the car for a spin, let the car warm up and set off to some open bit of country roads, the car felt normal under accerlation until 4k rpm where all hell broke loose, like another turbo ontop kicked in. Pretty happy with the map so far. I then noticed under certain conditions it would go spongey in 3rd gear at 5krpm and drop boost, so i emailed them and asked for a new map. The next day they had a new map sent to me, and so in the afternoon i plugged that in, and uploaded it, didn't really feel different at all, if anything car felt slower. the Next time i tried taking the car out, it would not start up, dash flashing like christmas lights, and fans spinning like mad. I Tried connecting up the bluefin device but got an E001 communication error. Tried contacting bluefin and think they were closed on evening of christmas eve. So the car does not start and its christmas eve, great. Tried starting it the next day on christmas day, no avail. Obviously they wouldn't be open christmas day, so emailed them, tried ringing them on boxing day with no avail. Now today I have tried ringing them again and they are still closed, with no information of when they next open. After looking on superchips website I saw a superchips dealer that listed a mobile number, great i thought, maybe he can help. Contacted him and he picked up and told me superchips was closed until the 2nd of Jan. So currently I have a brick in the shape of an A3 parked up, which is useless for over a week! thanks bluefin superchips, thank you a lot.
