Scanmaster readings

[Casey Jensen]

Just recently put a 86/87 ecm in my 84 with a 5.6 (basic chip with pump gas)from turbotweak. Haven't had a chance to drive it yet, but here are the numbers I came up with. Car was warm at idle.
O2- 650-725 Numbers jumped around a lot???
AF- 05
L8- 40
Bat-13.8
Int- 128
Bl- 120
Mph- 0
Clt- 164
Ats-71
r- 725
Tps- .42
Iac- 40
Mal-0

I am new with the info and not sure where the numbers are suppose to be and what is acceptable. Does this look good or is something way off? Are the O2 numbers suppose to jump around like that or do I need to replace the sensor? Thanks any info in advance.

Everything looks pretty good.

During idle and cruise it's perfectly normal for the o2's to jump around.

WOT on the other hand, the o2# should hold in the upper 700 lower 800mv's.

Thanks Rick, new to the scanmaster and just wasn't sure where the numbers was suppose to be before I took it out to drive it and pushed the pedal a little further.

Roger that!

Good reading here to help get a better understanding of those things.
