injector threshold

[drayrunner]

I read on hp that one of the v8 guys reduced the injector threshold to gain some ecomony, first i got a v6 that has 6 different steps for o2 sensor rich/ lean threshold state cold,idle,decel,normal,accel, and wot, i using tiny tuner, what i did was lower the lean threshold for normal , which i assume is cruise, i can't see any change, does know the correct way or whatever opinion you may have on the subject. thanks

This is what I'm using. I have picked up mileage with this.

Fuel (91) -> Open Loop & Closed Loop -> O2 Sensor Rich/Lean Threshold

mv Lean mv Rich
State Cold 500 675
Idle 375 425
Decel 320 380
Normal 300 400
Aceel 500 650
High 500 650

[TinyTunerData]
500,675
375,425
320,380
300,400
500,650

I tried these settings and it started to miss fire (I have 60lb injectors and running E85) and set a lean o2 code. did you have to play with the settings to get them to work?

Nope. I set them and noticed an immediate difference in throttle response and a little later in mileage. No misfires at all.
