Thank you
Yes you have to code for the 340mm I'm assuming you're using. It's a totally different clamping pressure and you need to have the ecu understand that due to the brake caliper and rotor size change. Coding you need ISTA and the cable. Do a search on the forum there are Memebers that can send you the ISTA program free and the cable is like $30-$40 bucks if I remember correct. I don't know anymore I'm not on these forums that much anymore.
