I have been using VER. 1.X and I downloaded and installed the new 2.0 Version. I still have the old cable but am thinking of upgrading this week.

I just installed SLP LT headers and I want to make a few runs to see how my O2 sensors are doing, but in the new version, it shows 8!!!

Which ones do I look at?

I also want to record this info, can I still use the space bar to start and stop the recording?

I am also going to spray a DRY 75 shot too. What other sensors should I look at when I spray?

Knock, Air Intake, timing?

Has anyone ever created a Q/A section for AutoTap to see what sensor does what and what reading is good?

What about Ltrims? Which should I look at and what values are good.

I hope some of you can answer some of my questions for me and hopefully I just overlooked the Q/A section for AutoTap....

Thanks in advance... <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

For monitoring strip runs:
-RPM
-Timing
-KR
-Front O2's
-I also monitor my MAF flow

For street monitoring:
-RPM
-Timing
-KR
-Ltrims

Yes, space still toggles logging on and off.

Thanks for the response!!!

Since the new Autotap software shows (8) O2 sensors, which ones are the front ones? There are (4) for Bank 1 and (4) for Bank 2.

What values should I be wanting for these:

For monitoring strip runs:
-RPM
-Timing
-KR
-Front O2's
-I also monitor my MAF flow

For street monitoring:
-RPM
-Timing
-KR
-Ltrims

RPM's and KR are easy but what about the others? O2's should be better than .870 right? Any less than I am lean???

What about timing? When I am N/A and Spraying, they should be different right? What is good?

I know a lot of questions, but we need a section that has all this basic info in it...

Heated Oxygen Sensors Operation

FRONT:

The Heated Oxygen Sensors are mounted in the exhaust system where they can monitor the oxygen content of the exhaust gas stream. The oxygen present in the exhaust gas reacts with the sensor to produce a voltage output. This voltage should constantly fluctuate from approximately 100 mV (high oxygen content = lean mixture) to 900 mV (low oxygen content = rich mixture). The heated oxygen sensor voltage can be monitored with a scan tool. By monitoring the voltage output of the oxygen sensor, the PCM calculates the fuel pulse width command to give to the injectors (lean mixture/low HO2S voltage = rich command, rich mixture/high HO2S voltage = lean command).

REAR:

To control emissions of Hydrocarbons (HC) , Carbon Monoxide (CO) , and Oxides of Nitrogen (NOx) , a three-way catalytic converter is used. The catalyst within the converter promotes a chemical reaction which oxidizes the HC and CO present in the exhaust gas, converting them into harmless water vapor and carbon dioxide. The catalyst also reduces NOx, converting it to nitrogen. The PCM has the ability to monitor this process using the Bank 1 HO2S 2 and the Bank 2 HO2S 2 heated oxygen sensors. The front HO2S sensors produces an output signal which indicates the amount of oxygen present in the exhaust gas entering the three-way catalytic converter. The rear HO2S sensors produces an output signal which indicates the oxygen storage capacity of the catalyst; this in turn indicates the catalysts ability to convert exhaust gases efficiently. If the catalyst is operating efficiently, the front sensors will produce a far more active signal than that produced by the rear sensors.

The catalyst monitor sensors operate the same as the fuel control sensors. Although the Bank 1 HO2S 2 and Bank 2 HO2S 2 sensors main function is catalyst monitoring they also play a limited role in fuel control. If a sensor output indicates a voltage either above or below the 450 millivolt bias voltage for an extended period of time, the PCM will make a slight adjustment to fuel trim to ensure that fuel delivery is correct for catalyst monitoring.
