Update:

Just received my 3rd eye TPMS from Viva. Its the same exact kit yay!

Keep us posted on your efforts, guys

I am talking to a colleague of mine in Taiwan, he will hunt down a supplier of the same kit - I found one via my google searches, he will check pricing, and possibly find the supplier.

I will keep you posted on pricing and a possible contact.

Br,

just curious, def not a deal breaker, but that would be cool to for some installs I think...

Yes, it's possible.
This afternoon I'll post a picture with the exact point where get the data out without opening the original TPMS display receiver.

With the "3rd Eye TPMS" kit is provided a power cable that ends in a white connector with 3 wires (Red - +12V, Orange - Ignition key ACC and Blak - Ground)
On the connector there is also an empty hole where can be added a crimp terminal, on this pin is available the signal received from the tire sensors.

So Robby, where would we hook up this pin on your interface to? I would assume one of the header pins on your interface board, but which one?

You must get data on JP2

You need to connect this pin to the JP2 and the pin with the black wire to JP3 throug a shielded cable.

Wow, this is great! I might actually connect your interface this way so that I can salvage the control/lcd part of the TPMS (for another install on a later vehicle!). I really don't want the display to be seen so I'll just do a stealth install of it (maybe put it in the trunk next to my car pc!!)

P.S.
I've received the components for the interface Robby, almost ready to populate the board and give it a go!!

One thing, if I hook up the interface to the car pc with no sensors mounted, will the interface read 0 for all the values of each sensor?

No, it will be displayed -- for each values like when the interface is not connected to the PC.
Don't forget to do before the "learn" procedure as described in the config utility in order to get all your sensors paired with the interface.

Just ordered my PIC =]

It's going to be a looong time before I can do this, but I figured might as well get the parts now =]

Sal R. · 11-10-2007, 01:53 PM

Just ordered my TPMS kit.

Got a skin all made up.

Just need to get ahold of the USB interface board and I'm all set...

juve021 · 11-13-2007, 07:11 PM

UPDATE:

Well I've etched the PCB, drilled holes and started to populate the board when I realized, I didn't mirror the image before I printed it!!!!! ARHHHHHGGG!!! Crap, oh well have to start again!

inh · 11-13-2007, 07:19 PM

uh... wouldnt it work the same anyways?

_Dejan_ · 11-14-2007, 12:37 AM

yes it work but he must put all elements on other side (on cooper side)...
