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.

"Hal, what should I dial?"

" Wait while I check the weather... Dave"

I am afraid it is going to say "Kyle, we are not going to run fast this weekend."

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.

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.

that's funny. I've run the car in closed loop testing, with it data logging. Normally to target it to a specific AFR. But I'd never do that in eliminations

Man, I'm dumb. I don't get it. Who is Dave, and is that Ted thing a button, or light, or???
Forgive me. I'm old. Probably some young thing I don't know about. :-(
