I finally got the Torque Pro app but...

I have no idea what the specs are for our trucks for different sensors and vacuum.

Here's some readings of what I got but I don't know what the specs are

Intake manifold pressure (at idle) 4.35 PSI
Timing Advance (at idle) 22-24 degrees
Mass air flow rate 47.33 CFM
Turbo boost+vacuum Gauge -10.35
Vacuum -21.1 at idle and about -12.5 at 1500 rpms
volumetric efficiency 58%

fuel trim bank 1 longterm - 8.6%
bank 1 sensor 1 -1.56%

short term bank1 1.56%

bank2 long term 6.25%
bank2 sensor 1 -1.56%
bank2 short .78%

idles at about 625-640 rpms it fluctuates
idle under load is about 550 rpms

turns out my rpm gauge in the truck is reading high about 300 rpms more

I have no idea if these readings are in spec. Anyone know of a source where I can find this info?

Also on the torque app a ton of stuff doesn't work like IAC, EGR, Knock sensor etc... If you have the app can you tell me if it works for you? thanks

idle is about right on reading the pcm which relies on cranks senso. tach signal is from coil itself.

MAF is supposed to be 5-7 gr/sec on fully warmed idling engine. I hope i messed up the math because that cfm converted seems way way off. I am still tired from trip so I assume I am goofing on the numbers.

torque does just ob2 standard pids i believe all the others you list I think are gm enhanced. ask about dash command. I saw a page on phone and tablet tio add gm enhanced pids but not verified yet on whether they work.

I came up with 6.25 gps within the 5-7 you said. Found the info from here http://www.eformulae.com/engineering/volume_flow_rates.php

okay my math was wrong then sorry. I am really burned out in the past 5 days.

I wasn't saying your math was wrong or anything I just looked it up to make sure my MAF was ok. I didn't know the specs of the MAF thanks for the info.

How are you liking the app? I've had it for a few months but I've had issues with it "forgetting" my screen setup. Sometimes I start it and it has the default gauges; sometimes it's blank. When it's blank, I have to go through the motions of adding the 6 gauges again.

I tried asking for help on the app's forum but that has gone no where. It's frustrating enough that I'm thinking of buying a Scangauge II, but it's $150ish. I did read on the site that issues like this tend to mean it's having trouble accessing the SD card for storing the data. I might try a new SD card first.
