Proform 850 dialing it in closer

You need to log more than just O2's to really understand whats going on.

2 x 02's
RPM
Vacuum
Fuel Pressure
G's


And throttle position, which I know you already have coming. I just wanted to add that in so no one reading this misses it.

I only have one o2 Chanel on this unit(less expensive unit) and don't have the money to buy all of them sensors
will have to be happy with 3 Chanel's

Left Bank o2, TPS and RPM.
Just when threw an extensive testing of my fuel pressure/volume, and had a vacuum gauge taped to my windshield,.....but would be nice. Gs gauge would be super Cool........
all of these require a sensor..........the 80 dollar tps broke the bank. Vary limited funds these days

I thing if i buy another sensor it will be drive shaft rpm.
