Has anyone noticed on C5 Tech's homepage for V1 install at the bottom it states:
"Stay tuned to the website for some information on how you can interface your V1 into the Corvettes serial data bus (J1850) and have the warnings appear on the HUD."
Does anyone have any information about this. What will be required for an install and is it something we can do ourselves?
Thanks

 

Man I am looking forward to that info!!!!!!!!!!!!!!!!!!!!!!11 :smash: :smash: :smash:

 

That'd be :cool:

 

I can hardly wait!

How do you find out if the serial data bus has the J1850 number. Where do we look?

J1850 is the communication standard for the GM obd-ii PCM.

I have more info regarding that stuff on my site:
http://www.vetteguru.com

 

I have no idea what that even means . I just pulled it off of his website.

 

Sounds like an urban legend to me........

 

The C5 has over a dozen computers (microcontrollers) that cooperate to make the car run, and they are all hooked together over a serial data bus. There is a standard for this bus, called the ‘J1850’, and it pretty clearly documented how many of the messages pass (most of them are related to the OBDII spec).

Now if you add your own computer to the mix, and it listens to the data on the bus, and upon hearing something in particular sends it’s own message, you can make the car do stuff.

A very recent example of this is the TopDown Tech, it just listens for a particular door lock/unlock message sequence, then sends a message to body and/or door control module to put the windows up or down. Notice how it plugs into the OBDII diagnostic port? That’s a convenient place to access the data bus on the vette.

The V1 also sends similar serial information to its remote display, so what I’m trying to build is a bridge between the V1 serial data and the vette’s computer network.

I’ve got the vette side pretty well researched, and I’m working on a prototype controller that can do some of what I need. I’m not yet sure if I’ll be able to drive the HUD without having to actually put a microcontroller in between the dash controller and the HUD, but I’ll figure that out one way or another.

The current problem is in decoding the V1 signals. I talked to Mike Valentine and he said they are working on getting the signal spec published, but that was over two months ago. He said they get regular requests for this, and they want to do it right so they don’t get lots of calls asking for clarification.

I’ll keep working on it this winter and post updates on the site. I wouldn’t be surprised if the makers of the TopDown Tech product are expanding what their microcontroller is trying to do as well.

 

heck i think the vette should come with a module that employs a raddar/laser detector. it would be awesome if the vette came with a built in raddar detector with an upgradable module that would allow it to change with the cops new equipment. If any one at GM reads this please put this on the C6.

 

Yeah, but it would be like the sound system. A low end model that we would have to rip out and replace anyway. Good thing they don't do that if you ask me. That way I don't have to pay for something I'm not going to use.

 

V1 on HUD would be too freakin cool! :crazy:

 

That will be cool! Makes one more reason to own a V1. Keep me posted

 

.... think how cool it would have been of the DIC display was visible on the HUD, and then that could be controlable via the databus. Hmmmm, lots of uses there :)

 

If this happens it's gonna cost me, and the Escort will be toast.

 

Too :cool:

Finally, a good use for the HUD.

 

Dude - that would ROCK! V1 on HUD! What could be better?!?! Well - neked chics of course..

Humm, you guys figure the data bus out quick! so we can write an app to have neked dancing chicks on our HUDS! :yesnod:

:cheers:

Sounds like your pretty close!
Count me in, I know that the wife would love to see the V1 in Blue instead of red!
Keep us posted,
Tim

 

Wasn't there a post a while back on someone modifying their rearview mirror to work with the V1?
