Legacy OBDII

Mugenlude · Post by **Mugenlude** » Sun Jun 11, 2017 1:09 pm

Newly installed legacy OBDII adaptor installed per the installation instructions (removed the old power wire)... I'm not getting any of the data I'm trying to pull (RPM and TPS).

2002 C5 Z06, RCP mk2 connected via Bluetooth module. Any ideas?

Hi, What firmware version are you on? If you are not on 2.11.0 then you will need to upgrade to the latest firmware.

After upgrading firmware, delete and re-add some basic OBDII channels - such as RPM, EngineTemp and TPS. Write back the setup and power cycle.

Let us know what you find out. thanks!

I'm not sure on the version of firmware.

I'm running Version 1.9.1 of the app on an Android tablet (LG GPad VK815), but I'm not seeing Firmware on the left menu (I also see Setup on the Home menu in lieu of Configuration like in your video). I have tried uninstalling the app, and reinstalling it thinking that maybe I just didn't have a current version. No change.

Hi,

Once the app connects to your RaceCapture unit - via wireless or USB - the firmware will be reported on the right side of the top bar. It should say something like

RaceCapture X.Y.Z

where X.Y.Z is the version number.

Hope this helps!

Ok, I'm only on 2.9.0.

Does the firmware update need to happen while connected to a computer? I'm trying to do so via the app on my tablet connected via Bluetooth. Thanks.

Yes, firmware updates can only be done while connected to a computer. You'll see an additional firmware button on the bottom of the left hand menu in the Setup screen.

Cheers,
Bryan

That explains my issues, thanks for the replies.

OK, firmware update completed... still not getting any data. Below are settings my settings....

Edit to add: I removed all of the OBDII channels, then added them back in, power cycled the RCP, and restarted the smartphone as well.

And here is the dashboard, as you can see, no RPM or TPS.

TIA

Hi,

There's a thing you need to do after upgrading to the 2.11.0 firmware, if you had OBDII channels defined previously.

Try this:

* Connect the app to racecapture
* Go to setup / OBDII
* Remove all OBDII channels
* Write the config to RaceCapture
* Read back the config, confirm no OBDII channels are defined
* Add just one channel. try RPM to start.
* Write this back to RCP.

* Power cycle RCP, and re-connect.

Do you see RPM now?

That did it! Awesome.

- Got RPM reading correctly.
- I added TPS, but the number is something like 2,1XX,XXX,XXX. I assume I'm going to have to figure out a conversion for that. Is there a tutorial somewhere I can reference to sort that type of thing out?

Thanks again for the help!

So, power cycle RCP after adding the OBDII channel. you shouldn't have to power-cycle, but there's a bug in the 2.11.0 firmware that requires it. We'll get that fixed in 2.11.1

Glad you got it working, and thanks for your patience!

Just took the car out to do some testing and the TPS data seems to have resolved itself, I'm getting good readings now.
