Best working alternative for OBD1 Hondata/Neptune/Crome would be tunerview which can read over USB or bluetooth, supports external inputs as any gauge you want to configure and looks pretty nice.

If you have a CAN bus assessible, RealDash is the way to go with a USB-CAN adapter.

 

I was trying to see if it works with S300 V2. I saw that it uses wifi but Im assuming that's only to connect to the Raspberry PI. I ordered all the parts and they should be here Friday so I plan on getting it setup over the weekend. If I run into questions could I message you? Side note it's awesome that this forum is still active.

 

I've looked into those. I like the DIY aspect of this project though

 

RealDash and TunerView are still tablet based though, and CAN with the Hondata is quite limited in available channels, and you have no control over what gets into the config.

HonDash connects through the ecu’s USB port and polls it directly for data packets, so it’s super reliable. I wouldn’t recommend Bluetooth communication for anything serious. The WiFi on the Pi is used so you can treat it as a headless pc and remote into it to edit the code, but there is also a setup tool that you access by connecting to the pi over WiFi (with your phone) and edit the settings of the dash. It’s pretty cool.

the downside of HonDash is that there’s not a GUI for building your own layouts, so if you want to expand it you’re going to have to put on your developer pants and learn to do some code. The backend is all python, the front end is all html and js. If you can build a decent basic website with websocket functionality you can probably figure out how to make this better.

I don’t know how helpful I’d be on getting you up and running, it’s been years since I put any significant time into it. I could probably answer some basic questions though.

 

So is there no GUI at all for hondash? Again I haven't gotten to mess with it at all. Is it just the back end, that gets installed on the Pi and I would need to build the entire display GUI?

 

No, it already has a couple of display layouts. There’s just no GUI for building more or rearranging the current ones - you’d have to be able to write the html and is to make it happen.

 

Ok. Yeah that's what I meant. A sample layout just so I can make sure it's actually working before I start designing a layout. I appreciate your help

 

You bet! Interested to see what you come up with. I wish I could have put more time into developing it. My free time for stuff like this usually happens while I’m sitting on an airplane, so it wasn’t a very practical hobby project for me.

 

Ill update the tread as I work on it. It's a cool project and it would be neat to get people interested and working on it.

 

Got everything setup and installed. Hooked it up to my S300 V1 in the car for testing and I'm at my first road block. The PI isn't reading from the S300. Not sure if this is because it's a S300 V1 and not V4, but now for trouble shooting

 

There's no such thing as an S300 v4, FYI.

I backed the protocol out of my v3. I've never had access to a v1 or v2, so it's never been tested unless someone else has put work into it.

 

I mistyped that. I meant V3. Im trying to decide if it's worth putting the work into getting it working on a V1 or just saving up for a V3

 

Afaik the protocols are all the same. They just added bluetooth and optimized the board layout.

​​​​

 

There’s also a vendor and product id that has to be requested so the pi knows what device it’s plugged into and what protocol to use.

I would expect v2 & v3 to be the same, v1 is definitely different since there’s no analog inputs.

It’s totally up to you, obviously, whether or not it’s worth it to put work into decoding the v1. I think Hondata still offers a trade in credit for a v3. I personally wouldn’t devote much time to sorting out a long deprecated board.

 

They do still offer the upgrade. I need to upgrade anyways. Pretty sure the battery on my V1 is already on borrowed time. Well guess I'll update this thread when I get a V3

 

I’m just getting into this and want to work on the layouts and getting all the parameters accessible, would you be willing to share some of the layouts you worked on? I’m just learning to JavaScript and would like to see a working example so i can tinker with and get a better understanding of it.

thanks in advance.

 

I honestly haven't put time into this in years and don't have anything useful to share. Went down the rabbit hole of learning JS, which was cool, and adding backend features. It was a good exercise learning how to manipulate someone else's coding strategy.

Big hangup for me was not having a development/isimulation environment that I could use on a PC. I just don't have enough time at a desk to be chained to an RPi (most of my free computer time happens while sitting in an airplane), and I've mostly stopped using HonData. There are also products out there like PowerTune (that IS an RPi dash but ready to go). I do still think it's a cool project..
