New obdII in...read stats!

[marioc89]

I just got my obd in last night and was going to get some stats from my truck and post them for you guys to read and let me know what's going on. I wanna know why I'm using so much fuel mainly and other misc things.

[marioc89]

Anyone care to help me out on this? I could really use some help on how to read the info that the obdII gives me.

Boost (in psi) would be useful to monitor and log. Might as well log the upstream sensor voltages (sensor 1 in each bank) to see if any are fluctuating wildly or are barely within spec.

[marioc89]

Which could I look at to see why I'm using so much fuel?

[Towncivilian]

Is there anything like injector status that is able to be read? Maybe an injector is stuck open.

[marioc89]

Which one do I read that on? What reading is what I'm saying.

[Towncivilian]

When adding displays to Torque, sensors that can be read are highlighted in green. I don't have my Bluetooth ODBII adapter at the moment so I can't go out and check which can be read. In the list when adding a display, do you see something like "injector status"?

[marioc89]

I'll check.

[marioc89]

No. I don't see any such thing.

[Towncivilian]

It's difficult to diagnose using generic scan tools, especially with our older ODBII vehicles that don't offer access to nearly as much data as more recent vehicles.

Log the oxygen sensor voltages for both upstream sensors and post a couple hours worth here in a spreadsheet, I can take a look at it to see if one of the sensors is getting lazy or is barely within spec. Do the same with boost (you can include the data in the same spreadsheet). You have to set up which PIDs you want to log in Torque's settings, then the data will be saved to spreadsheets in the "torqueLogs" folder on your SD card.

Which are upstream sensors....bank 1?

[Chuck Tribolet]

Bank is left/right, not upstream, downstream.

[marioc89]

Well that's what it shows me. Which is it?

[Towncivilian]

Bank 1 & 2, sensor 1 (each side) is what you'll want to log.

[marioc89]

Ok. Cool! Thank you!

[marioc89]

One more thing. I'm still learning how to use this so could you explain how to retrieve what I select to log on my sd card? How how to setup where to save it? I tried going to the files that it did make on my sd card but it won't let me see them.

[Chuck Tribolet]

How you read the log files will vary from reader to reader. I'd suggest a look a the manual for your reader.

When you connect your Android smartphone to your computer, you should be able to access its SD card. There will be a folder called torqueLogs within, with files which can be opened by Microsoft Excel or another similar spreadsheet program. If you can't access the SD card when connected to your computer, you may need to change USB settings to "mass storage" mode, which should be in Settings -> Storage -> tap the "menu" button.

You can zip up the logs and upload them somewhere (Mediafire, perhaps) so we can take a look at them.

[marioc89]

Ok. Good deal!
