The tuners been doing it for ten years +. No matter what, he gets the fuelling spot on and then a couple drives later, it's back to being extremely rich again. This morning going to work, it was rich like normal, 12 hrs later and on my way home the ltft's were -7ish and the stft's were -3 to +3 and were balancing each other out. An hour later I seen ltft's in the 30's at idle. This is all in closed loop, but going down the long hill in town I drop it down into second to keep the speed rather than ride the breaks and when it's like that, it goes into open loop. I hit the throttle and it's back in closed and back and forth. This has more mood swings than the wife.
