Proform 850 dialing it in closer

So purple is o2
Black is rpm
red tps
Tps is not calibrated so it goes below 0 at idle
2nt one is the same one, only expanded to see it better.
the flat line at the top is because it is reading more then 20% oxygen.(o2 sensor several inch away from the opening of the collector). aka open exhaust.

the last on is still the same one only showing that when it quits it flat line until i turned off the recording.

So tell me what you see............................
