I went to get a remap this morning taking it to 250bhp however I had a window fault in January which BMW updated my ECU software, this has locked out the map editing ability and the mapper said "you will need a chip soldering on to the ECU" is this true or is there anyway to get around it?
(I only wanted a software remap with no chips as they are a lot more undetectable from insurance and BMW point of view)
Thank you in advance
