Extended OBD PIDs for Nissan - TheBasedDoge - 08-12-2020

Very cool. Working on trying to get the obd setup with my car.

I found a list of of extended PIDs for Nissan. Does it support extended PID? here is an example of what I found

PID           Bytes A   B C D Name Description
1101 4353 1 61          Engine Coolant Temperature °C = A-50, °F = (A - 50)*9/5+32, Same as Mode 01:05, but +10
1102 4354 1       00          Vehicle Speed kph = A*2, mph = (A*2)/1.60934
1103 4355 1       96          Battery Voltage V = A/12.5 or V=A*.08
111F 4383 1       5F          Oil Temperature °C = A-50, °F = (A - 50)*9/5+32, Same as 580:E

So would I make my config in OA this? (for example, oil temp)

[ObdInfo_9]
Query=111F
MinValue=0
MaxValue=100
Limit=0
Formula=a
Label=Oil Temp
Precision=0

I am also interested in this.

There are extended PID's for my truck for transmission oil temp. It does not have a dipstick to check the level, so the procedure to check the level is to warm to fluid to within a certain range of temperature, then pull a small plug on the pan. At the right temp only a trickle will come out. Thank you Toyota.

Please follow this guide: https://bluewavestudio.io/community/showthread.php?tid=1858
and let us know what is the result in your car.

Your PID should look more or less like below (add it to /home/pi/.openauto/config/openauto_obd_pid_info.ini file):

[ObdInfo_X]
Query=111F
MinValue=-40
MaxValue=215
Limit=90
Formula=a-50
Label=Oil °C
;Formula=((a-50)*1.8)+32
;Label=Oil °F
Precision=0

Please adjust label, unit, limit and max/min value for your needs.

X in ObdInfo_X must be replaced by the consecutive value. Also please remember to increment the

[ObdInfo]
Count=9

value. Once you define your PID, you can add it to the Dashboard. You can create new Dasboard or replace one of the PID in the existing one. Query value is the unique identifier for the PID.

RE: Extended OBD PIDs for Nissan - TheBasedDoge - 08-13-2020

None of my custom PIDs are working Sad

additionally, the obd connection itself does not seem stable. It works for a little while but the it freezes and stays at the last value.

I am using this adapter
https://www.amazon.com/gp/product/B005NLQAHS/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

Which has always worked perfectly with my phone. Additionally I am able to get all this data from my phone app (OBD Fusion) so it must be some wrong setup in OA.

pics attached. I am going to mess around with it more. But I also need to figure out why the connection isnt very stable. Oh, also I changed the update speed to 3 from 5. Not sure how fast i go? its quite slow to update while its working.

RE: Extended OBD PIDs for Nissan - BlueWave - 08-14-2020

Great there is some progress. Please provide us logs located in /home/pi/.openauto/cache/openauto.log file. It would be great to catch the moment when adapter is disconnecting (or some symptoms of unstable connection are visible). Also please post configuration of PIDs that you have added.

RE: Extended OBD PIDs for Nissan - TheBasedDoge - 08-14-2020

Ok, I fixed the disconnection issues. its a bad BT adapter. I switched to my Asus BT adapter and it seems stable and even updates faster, so that's fixed. Now onto the PIDs.

Oh, I also attached a datalog i found online of someone who has mapped out PIDs on a 370z. You can take a look, maybe I am missing something there also.

My end goal is to also figure out how to show the climate temp if possible on the OA screen, also the individual tire pressures (this i know can be seen from OBD since OBD fusion can grab it)

RE: Extended OBD PIDs for Nissan - BlueWave - 08-14-2020

You have to adjust value of the "Formula" for your new pids to get meaningful values. But that should not affect the querying. Any chance to get the log file?

Please also try to add 22 at beginning of each custom query (e.g. 22111F). We found on the internet that PIDs you are trying to query are available in mode 22.

RE: Extended OBD PIDs for Nissan - TheBasedDoge - 08-14-2020

Ah ok. Will try adding 22. I will get the log file for you also shortly.

Looks like logs from startup. There is nothing regarding OBD. Please try to zip them and send at software@bluewavestudio.io
