Obd ii scanner

I was wondering if anyone is using a scanner for the OBDII port to read other parameters that may be available. Whether it's a hard wire like the Scan Gauge II or wireless Wi-Fi using a app for your phone.

I plan on towing a travel trailer in the future and would like to mainly access Exhaust Gas Temp, cooling system temp, etc.

If using a Wi-Fi type, does the signal interfere with any of the electronics of the vehicle? I kind of remember reading a post or blog somewhere that that could happen. Looking for your recommendations.

Thanks Wireman

Re: Obd ii scanner

Here's some OBDII data.. specifically EGT plotted against several parameters.... note can run up to 700C quite readily.. the car was not towing
when this data set was collected.

Re: Obd ii scanner

Thanks for the replies. The more I look at these links, the more my head hurts trying to figure out what to get.

First off, I want to make sure that the EGT parameter is reported to the OBDII port. Will someone confirm this? That and reading water temp is my main reason for buying 1 of these. The DID already reads out the trans fluid temp & engine oil temp which is great. It also has to work with the I phone 6.

Can someone give me a specific dongle and app they are using, that will meet my criteria.

I'm not the most tech savvy guy, so specifics will help me a lot.

Thanks again. Wireman

Re: Obd ii scanner

I use a VGate iCar 3 WiFI as it powers off when not used; you need a WiFi one for iOS


No idea about EGT, you can get DPF level and CAT temp via entering custom PIDs, therefore you need an app that allows custom PIDs. I have OBD Fusion

For some reason it crashes on me at the moment (iPhone 4S iOS 8.4 jailbroken) but I can't see other complaints on their reviews, so it seems to just be me.

OBD II PIDs


% DPF full calculated value.

Name: DPF % full
Mode: 01
PID: 8B
Min: 0
Max: 100
Units : %
Equation: C*100/255.

"CAT temp Bank1 Sensor1"

Name: CAT Temp
Mode: 01
PID: 3C
Min: -40
Max: 6513.5
Units : C
Equation: ((A*256)+B)*0.1 -40

Can you please stop making your entire posts in bold, it does make it harder to read.

Re: Obd ii scanner

Snuke, Will do with the bold type. It made it easier for me to see. I'll revert to the old guy glasses for typing. Thanks for your posts to help me out.


Can anyone confirm if the EGT & water temp parameters are available for the scanner to read? Thanks Wireman

Re: Obd ii scanner

EGT is available. Water and transmission temps aren't accessible via general purpose OBD-II at this point, but, as a poor consolation prize, they are in EVIC.

Here is a subject-specific thread:
Ecodiesel specific PID's?

Conversely, the Scan-Gauge can access trans temp, but it isn't as otherwise versatile as using Torque or another similar app. The reason we don't have access to these PIDs in Torque is we don't know the secret initialization command that Scan-Gauge has. Yet.

Re: Obd ii scanner

I'm using Torque app, veepeak bluetooth dongle, and an old android acer 7" tablet. Works great.

Currently I have Engine oil temp, DPF temp, DPF soot %, Backpressure psi, Boost, Turbo VGT position, Intercooler temp.

The data stream has 100s of parameters so i'm sure more PID's will be found.

Re: Obd ii scanner

Roadkill, I may be wrong but I don't think the water temp is available on the EVIC. I have trans fluid temp and oil temp but I didn't see WT. Wireman

Ah, you're absolutely correct; I misspoke. I guess it may have been wishful thinking on my part... just like I wish for the engine hours readout that was on the 2013 EVIC (haha).

Hi Wireman.

I recently purchased An Ultra Gauge. UltraGauge OBDII Scan tool & Information Center

It has several features that I like and can display up to 8 pages of info. It plugs directly into the OBD2 port and sits nicely on the rh side of my dash. I have page one set for Coolant Temp, Cat (EGT) Boost pressure and fuel usage. Easy to toggle through the pages.

Pete

Re: Obd ii scanner

Pete, I was looking at there website and it said that some diesels will report oil temp rather than coolant temp. I see you are getting the coolant temp so that must not be an issue with the 3.0 eco diesel.

Does this interfere with the dash display at all? Even if you have the same parameter displayed on both the dash display and the ultra gauge? Are you able to get most of the available parameters?

Looks to be a good price also. Any issues setting it up?

Thanks Wireman
