Hello people im not new to Audi, but I’m new to the forum. I’ve recently part ex’ed my 59 sline A6 for a 66 A3 saloon, sline Quattro 2.0 tdi 184bhp. It has the stronic box on it. I’m looking to get the chip remapped. Several vendors have said they can add launch control on the remap. I was under the impression that launch control needed dedicated hardware that you find on S and RS models??? Or is it simply an upgrade to the software ??? Any ideas?? Thanks
