Ok I now have all of the tools needed to tune my truck. The BR-CAN tool for the closed loop and the LM-1 for the open loop. Now I have been working with the closed loop and know how that works. What I need to know from the tuners is when tuning the open loop portion of the map once you know your in open loop mode do you steadily drop the AFR from 14.7 (closed) to 12.5 (WOT) or do you immediately drop the AFR close to the 12.5 and try and keep it there. I have read the U-Tune book like a dozen times. I've been reading it even before I had my URD intake or MAF Calibrator. I just want to make sure that I'm tuning it correctly.:thumbup: Any help will be greatly appreciated.
