I am going to assume what you bought is an Actron 9690. Question is, how do you get real time data like your pics show with OBD1? Only way to do anything like that with EECIV is through the J3 port and that Actron tool will not support J3.
You use the self-test plug and the data out pin gives the data.

Did a little checking and it would seem that not all EECIV ECU's support data stream. Is this later models only? Quick check in a Chilton's manual, (Yeah, I know!), looks like 90 and later have 2 extra circuits to the self test connector?
For instance I have a Fuel PW (pulse width?) of 7.9
Is that good or bad? High or Low? Normal or abnormal?
IAT (intake air temp) is 118 - again, good-bad-high-low?
No manual came with this unit. I guess I have to download it from Actron.
My truck is a 95 F150 4.9/auto - Runs GOOD! but I have crummy gas mileage. I've done all the other routine maintenance stuff, but I feel I could be missing something.

Subford, so I'm stepping back into a 94 F150 with OBDI. WOuld you recommend the CP9190 scanner? I currently use the Torque app with a BT>OBDII adapter on my Cobra. Thanks!!!

Pulsewidth isn't really meaningful. You should be looking at the O2 sensor voltage - make sure it's switching between ~0.1-0.9 volts regularly. You should also be looking at the fuel trim. I see yours is at -5%, which indicates the computer is pulling some fuel.
The computer is removing fuel, which is the opposite of what would happen with a vacuum leak. If your O2 sensor has over 100,000 miles on it, it should be replaced.

I just replaced it about 3 weeks ago - Used the Motorcraft one too!
