I have a 2011 SHO, still stock, recently purchased that I suspect needs the knock sensor wires tweaked. I plan to do it once my CAI, new T-stat, and plugs come in. In the meantime before then (going home today) I would like to get some KR values to confirm that my sporadic lethargic behavior on WOT is due to perceived knock and timing modification by the ECM. I have and run Torque Pro on my phone all the time while driving. I installed the plugin for KR, but didn't figure it out or rather it didn't work and it screwed up all my other real time viewers (0-60, HP, Torque, coolant etc.) So I uninstalled it. I'm not real thrilled with Torque as it is (I do not trust its timing of various acceleration and torque and hp calculator) and saw FORscan Lite mentioned. I see that it is not free, but cheap. My question is does the issue of the KR plugin on torque sound more like a bluetooth adapter issue? If so and if I need to buy a better adapter that is known to work best I will. I see that FORscan is picky with adapters as well and see no point in buying that right now if it won't work either.
