Once you download the file you just click flash and it takes about 2 minutes to map the car, during this time you generally scare yourself thinking you are going to kill the car then it finishes and you get every drive train error you can think of (again more panic sets in). Click online recode and they all clear and you are good to go.
The other option is to buy their Wifi reader for £299 or make one for £50 (I made one) and then it links to your phone so you can do this process via your phone. Once running it displays all the key information about the car and how it is running, they recommend you do a few data logs and send it to them so they can check everything is looking good. There is also a good facebook group that people post logs on to get people to check it looks safe.
You can also hardwire a device in so it shows data on a phone all the time, ie oil temp, boost, etc.
You can also get custom tunes for your car via their app, lots of tuners all over the world will make you a custom tune but the are expensive and the OTS one works well for me.
The app also lets you change the burbles (a bit chavvy but I have mine set to min and it just makes a nice noise on a down shift), open the exhaust flap, disable the cold start etc.
It wont be as good a as custom map done on a rolling road which would cost around £650, but you can self map it back to standard and relock the ecu, change the maps to different settings yourself. They are constantly updating the maps following customers data logs and feedback so you have to update your map every few months / weeks, they add more features going forward aswell. I am going in for a end of warranty check and will just flash it back to standard first just to be safe, don't think anything is wrong with the car but BMW called and offered it so thought why not. I mean if anything is wrong they will know it has been mapped but I think its worth the risk.
Does 0-60 in well under 4 seconds now and generally just feels much nicer to drive.
