Realtime readout
« on: 29 January 2009, 12:54:55 »
Is there any way to connect something to my 99 2.5 V6 to get a realtime readout of whatever is readable (speed/temp/voltages etc)?
I'd like to connect it to a computer and write an interface to dispaly it all.
This would be part of the software I'm planning on writing for the computer which will eventually be going in the car (with a touchscreen).

Thanks

You mean like a Tech2?  Not sure if you could use the basis of one of the cheapo ones and integrate that..?  Is it an ELM327 or something similar?

Something like that, yes. But I haven't noticed an OBD socket on the car; will it have one?

Just found it now.

Don't know why I didn't notice it before.

Thats the sort of thing I need anyway. And they are the sensors I'd like to read too so I think I'll go for one of those.

Does anyone know whic protocol the Omega will use with the OBD?

An ELM327 would do the job nicely if you had a 2.6 / 3.2. It won't work on the NON-OBDII ECUs though.

Cocks!

What do I need to find for mine then?

The only affordable DIY interface that talks to the earlier ECU is the so-called "cheapo tech2" where the cable just contains a level shifter and communication appears to be achieved by bit-bashing the serial lines. Needless to say they're not very reliable and completely intolerant of USB to serial interfaces. I guess you'd need to implement the whole protocol in a similar manner in the absence of an ELM type chip to do it for you.

Personally I'd implement the low level ISO interface in a microcontroller and provide a less time critical protocol to link to the PC.

Getting hold of the interface specs could be difficult as I think they're not in the public domain. (not without payment, at any rate)

Might be able to get hold of some ISO specs (K bus and the like) - probably won't be for GME, but if they're generic...?

Used to work for a company who made lineside test kit for certain UK car manufacturers in the midlands..and still in occasional contact with some of them.  They might have some "personal backups" lying around..
