Data geeks might appreciate this.

Okay I just geeked out with my OBD and ChatGPT.

I recently took a camping trip from Washington state to Utah. On several parts of my trip south I was recording my OBD data which created CSV files to my iCloud storage. Out of curiosity I had ChatGPT tell me what, when and where my highest transmission and coolant readings were and it gave me that information and the coordinates.

I did this by making all the csv files from my trip into a zip file and uploading them into ChatGPT. ChatGPT showed me where my highest temps happened and when. It also asked me if I would like it to create a map listing all the temperature variations along my trip from all the CSV files for a Google map, so I said “sure”. ChatGPT gave me a file to upload that color coded sections of my trip at what range my transmission temperature was during it. Then I uploaded that file to Google Maps so I can look at different parts of the trip.

Very geeky I know but pretty cool and seems like a nice way to keep track of what your truck is doing. Now I have to figure out what of the hundreds of modules, I want the OBD to track for my next trip.

Here's a link.

Note: this isn't one continuous route. My OBD didn't always auto-start when I started the truck.

What this file shows

The entire route from your CSV logs

Drawn as multiple line segments

Each segment is colored by TFT temperature band:

Band Approx Temp (°F) Color (in map)
very_cool < 140 Deep blue
cool 140–160 Teal
normal 160–180 Green
warm 180–200 Yellow
hot 200–220 Orange
very_hot > 220 Red

You should post the image of the Google map it created. Sometime next year (maybe March or April) my 2026 should be ready to pick up from Granger. I'll be driving it back to Phoenix. Might be something cool for me to do.

I went ahead and added the Google Link in the original message.

Way cool - What OBD setup do you have onboard

I have an OBDlink MX+. I used OBD Fusion for my software. It's the same as OBDlink, but you can see some settings on your Carplay screen.
