Oil Temperature OBD?

Post by 16nz34 » Sun Apr 14, 2019 11:07 pm

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?

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?

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

????

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.

LapTimer expects EOT as Celsius, so the formula is “=A-50”. Channel is EOT. Request frequency should be low or medium.
