370z CAN Bus Data & Question?

There's a few people who have tried. Here's a couple of threads on the subject.

Thanks for taking the time to find and post those links.
I feel like I have searched every inch of the internet for Nissan CAN bus logs and have been up and down those threads many times

Most people that want to reverse engineer CAN bus like to do so on an electric car, as they want to know more about the battery state of charge.

However, there is a lot of interesting data on our own CAN bus that could be useful.
For example, here is the raw data from the steering wheel position sensor:





The steering wheel data is updated 100 times per second, and it contains the steering wheel angle,
rate of steering wheel turning (degrees/sec) and some other stuff I haven't figured out.

Just hoping to wet someone's appetite

Hi,

I must have a CAN bus adapter somewhere and can get an ODB2 connector.

Care to share more details on how you are grabbing the logs and save me the googling part?

Sort of interested on this as well.

Absolutely!! That is what I LOVE to do... Learn and share

I designed, built and programmed a CAN bus to SD card recorder. It uses an $8 ESP32, a $2 CAN bus transceiver and a $2 SD card module.

I simply plug it into my car and go for a drive. It records all the CAN bus data to the SD card.

On a manual transmission G37, it records close to 1200 CAN bus messages per second and on an automatic G37 with AWD, that jumps up to 2200 CAN bus messages per second. (Thanks again Kevin & Andy!!)

Then I use SavvyCAN to visualize the data, reverse engineer it and build a "DBC" file that defines everything. (well not everything... some items are very difficult to figure out!)

The CAN bus data is saved in a "SavvyCan" format, so it makes it easy to open it in the FREE and EXCELLENT SavvyCAN program.

I am 90% done designing an easy to assemble kit that allow you to do this without any electronic or programming skills. I think everyone should be able to do this for under $50 an not spend $300+ for the commercial CAN to USB/SD kits.
