Software On ELM Street - OBD2 Software Development

[Tazzi]

And heres the current app...

Am trying to collect a good list of PIDs. I see that there are soe on the "fieros" site (or whatever its name is). Might have to scroll back a few pages to check what the tech2 was sending with the dynamic PIDs list.
Anyone with a good defined list of PIDs thats willing to donate is much appreciated!

And also the ability to 'test' which pids are available from the pcm.. Im sure I read something in the elm manual.. but seems nothing in there ever applies to GM!

So according to the elm datasheet.. sending off 01 00.. should get the pcm to send back the valid pids
eg [08:56:11:200] Received: 68 6A F1 01 00 17
[08:56:11:263] Response Found: 48 6B 10 41 00 BF BF F9 90 B5

Good old wikipedia to the rescue!

A request for this PID returns 4 bytes of data. Each bit, from MSB to LSB, represents one of the next 32 PIDs and is giving information about if it is supported.

For example, if the car response is BE1FA813, it can be decoded like this:
BE1FA813
1 0 1 1 1 1 1 0 0 0 0 1 1 1 1 1 1 0 1 0 1 0 0 0 0 0 0 1 0 0 1 1
Where each bit matches up to a PID: 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 10 11 12 13 14 15 16 17 18 19 1A 1B 1C 1D 1E 1F 20

Therefore the support PIDS are: 01, 03, 04, 05, 06, 07, 0C, 0D, 0E, 0F, 10, 11, 13, 15, 1C, 1F and 20

Therefore looking at our LS1 PCM response:
BF BF F9 90 = 1011 1111 1011 1111 1111 1001 1001 0000
So supported PIDs for mode 1 are: 1,3,4, 5,6,7,8, 9,B,C, D,E,F,10, 11,12,13,14, 15,18, 19,1C

hmm.. I am surprised that 0x20 isnt supported.. since that would indicate the next 32 bytes of supported pids.
..So just test pid20, and it sends back: [09:09:26:528] Response Found: 48 6B 10 41 20 80 00 00 00 02
meaning 80000000 = 1000 0000 0000 0000 0000 0000 0000 0000
Thus only PID 21 should be supported... which sends back: [09:12:11:004] Response Found: 48 6B 10 41 21 00 00 E6

And testing all other locations results in nothing.

I guess you can only access most pids from the enhanced pid requests system..lets see whats supported there.

VZ V6 ecu on the bench as well now *Woop Woop!*

Just... need to figure out how to wire it up!

All the enhanced pids support by the LS1 pcm:

From what I can see, I need to hook up:
X2–55 BN 2501 GMLAN Serial Data Bus – Low
X2–23 BN/BK 2500 GMLAN Serial Data Bus – High
X2–25 BK/YE 510 Low Reference – Ground 7
X2–36 OG/BK 740 Battery Positive Voltage

Is there a single "ignition" wire that needs to be hooked up?
Pins 1, 3 or 17 maybe? ANy input would be greatly appreciated! Dont want to fry this bugger!

[Holden202T]

jayme might be able to help, I think he played with one of these for a mates race car ?

[Tazzi]

Might have to hit him up for some help then.

Was hoping there would be a diagram on efilive/hptuners but I don't see one. Only see the ls1 PCM.

[VX L67 Getrag]

sorry been busy these are the exact wires the E55 VZ ecm needs;
Pin B3 - Pink - Ignition
Pin B23 - Brown/Black - Can Hi
Pin B25 - Black/Yellow - Fuel Level Sensor for Ground
Pin B36 - Orange/Black - Batt Supply Voltage
Pin B55 - Brown - Can Lo

Thanks mate! Will add the ignition wire and give it a go this arvo. Should hopefully have some 11bit CAN support over the next couple days!
Just need to find something on 29bit too.. since I think the VZ v6 were only 11bit from what everyone was testing?
