OL or CL with the MAF and LT's
OL or CL with the MAF and LT's Hey to all...
I have asked about the difference between WB and NB and now believe the problem is the collectors and getting the NB's good and hot, then they read better.
I have tuned the car with a AEM WB and now have new NB's in and in the Part Throttle areas, the AEM and NB's give me pretty much the same percent error, it's at idle that the NB's are off until they get good and warmed up they can read anywhere between pos ~10 percent to neg as much as almost 20 percent of error. When they read 10 - 20 percent off the idle gets rough, it hasn't stalled is rough, but after good and warm they settle down and the idle gets much smoother.
Question is until they get warmed up and settle down is the amount of error dangerous to the motor, other than this the car is running well, just don't want to hurt the motor and am wondering if I am wasting fuel?
I would like to run CL for safety, but is this really safer?

If you disable CL does it go back to being close? If you've got it pretty close in OL, just leave it there.
CL for safety? No safety, it's just better for the cats and fuel milage.

I would guess that OL would net as good or better mileage, due to the o2's not bouncing around and falsely moving fuel.

It should go into closed loop pretty much as soon as you step on the gas.

The Fbodies don't seem to work very well. I've had some that won't go back to CL once they go into open. I've had some that work pretty good.
Seems the Vettes work pretty flawless though.

I don't have a license for your PCM so I can't make the changes.
I made the changes to the PE tables according to the thread and it makes sense to kick in to PE just command 14.7 up to 1200 rpms, but it doesn't work on my car, or the OS which is the stock 02 system.
