Even some respectede tuners are trying to hit 10.5-11:1 (.96 narrowband approx) across the board. No clue why as the engine doesn't need that much fuel at low revs.

I totally agree with you, my tune starts at 14.0 at 2000rpm and richens up to 11.7 @ 4k than approx 11.3 after that. I found the car is more "awake" at lower rpms this way.

Thanks for posting the HHH data log, I also have the HHH data logger. My tuner had issues with making the fuel trim high and fuel trim low the same. He said my o2's were causing the car to dump more fuel and the eManage Blue is not able to control it.

Here is my log cruising at 2500RPMS.
