Oil Temperature OBD?
Oil Temperature OBD?
Using OBDLink MX+ and the Grand Prix version of Harry's Laptimer in a 2016 Nissan 370Z. When using OBD Fusion I have access to the Nissan 2016 Enhanced Diagnostics which provides engine oil temperature through the ECM. This PID does not appear to be available using Laptimer?
Re: Oil Temperature OBD?
I assume your Nissan does not provide oil temperature using the standard OBD PID. This means you need to configure a custom PID. You need to find out the mode and PID used for your car before setting the Custom PID in LapTimer’s Expert Settings.

Ok, how would I find the info for that PID?
Re: Oil Temperature OBD?
Using Torque Pro you can create a custom PID for engine oil temperature as follows:
OBD2 Mode and PID: 22111f
Long Name: Engine Oil Temp
Short Name: EOT
Minimum Value: 0
Maximum Value: 260
Scale Factor: x1
Unit Type: F
Equation: (9/5 * (A-50))+32
OBD Header to Use: 7e0
Diagnostic Start Command: 10c0
Diagnostic Stop Command: 1081
So, how does that all translate to what you have under "Expert Settings", "CUSTOM PID 1" when all you have is:
Channel
ECU
Mode
PID
Request Frequency
Formula

Re: Oil Temperature OBD?
Looks like Mode would be Mode 22 and PID would be 111f. Guessing that Channel would be OBD Standard?, ECU ALL and Formula would be (9/5*(A-50))+32 for Farenheit.
Re: Oil Temperature OBD?
LapTimer expects EOT as Celsius, so the formula is “=A-50”. Channel is EOT. Request frequency should be low or medium.

Re: Oil Temperature OBD?
Yeah, still not working. I set request frequency to medium, guess I can can try low.

You can create a log like described in the FAQ "Debugging OBD Connections" (see FAQ section on this forum) and I will check how the communication goes. Take care to start logging before connecting and give enough time so the full dialog is captured.

Re: Oil Temperature OBD?
Hi Harry, according to this page https://en.wikipedia.org/wiki/OBD-II_PIDs its possible to set fuel, EOT or brakes in custom PIDs?

Re: Oil Temperature OBD?
Yes, in case you know your car’s custom PIDs and the manufacturer uses one of the modes $21/22/23. The former is difficult for many brands including the Volkswagen Group as this data is kept as a secret. Some use encryption to keep 3rd parties from adding value for their customers.
