Re: Fuel injection? Open or Closed loop?
It will only read one period.
I have yet to see one run faster in closed loop. Have seen several faster in open loop. If the car is slow enough you might make it work. I haven't seen one correct fast enough to work all that well with even a ten second car. Usually ends up not consistent. Tried it several times, won't waste my time with it again.

Re: Fuel injection? Open or Closed loop?
I'm with Ed! I don't like my dial-in changing as I'm heading down the track. It would follow the air 2 runs then, change 3 a different direction.
I clamped the correction amount, and realized, what are you really correcting? Open loop it follows the air like a carb car and I understand that. Tim |

"Hal, what should I dial?"

Re: Fuel injection? Open or Closed loop?
I started this post 4 years ago.
I run in open loop seems to work fine. I have a quick tune feature that I can type the AFR ratio I want and it does the math to adjust. But after the run not while going up the track.

Re: Fuel injection? Open or Closed loop?
Always open loop unless I am trying to see how much the O2 sensor is correcting. Then I will make a throw away run in closed loop, make an adjustment and stick with open loop.
