Nope. BB only tunes the ECU with HPTuners. Turn signals are a part of the BCM. HPTuners doesn't do BCM modules...EVEN though it's stated in their friggin add literature. I would not have bought HPTuner if I knew it only did the ECU!!! I had to get a Tech2 to do the BCM's. Ugh!really? Maybe its the tow tune from BB that changed it for me
