GMH V6 communication problem

[davewanna]

I have got a VX commodore engine in a different vehicle that I am trying to talk to with EFILive V4 with an ebay USB ALDL cable.
I am hoping my issue is just timing settings, but I don't have enough knowledge to work out the right settings.

Chatter capture is a repetition of this....
The first line is my current heartbeat.
I have 3 GMH VX V6 files, one is UPDATED, the other is FIXED. none work, each show similar issues.
Can someone who knows more than me share their wisdom?

Thanks!

Very shortly after posting and looking at timing I changed my T2 to 200ms and I did get it to connect and work!!!

However while running, if I hit the green button on EFILive, it doesn't always connect. Shows....

As a further follow up, to connect it seems I have to hit the green button in EFILive shortly after switching the ignition on.

If I leave the ignition on (engine running or not) for 20 seconds or so, it will not connect. Just shows what I pasted in my last post. Why would this be?

On a side note the program seems like it does what I want it to do so I will be buying the pro version.

[Blacky]

When you see the "Comm timeout: Expecting frame header byte", that just means the software waited for "x" milliseconds but no data was sent by the vehicle prior to "x" milliseconds elapsing.
"x" milliseconds is defined by T3 (when T1 and T2 are set to 0)

In your first post, I presume T3 was set to 100ms and the time between these two frames is larger than 100ms:

44:49.744: (44:49.744)$08,$55,$A3
44:49.857: Com timeout: Expecting frame header byte
44:49.864: No chatter found
44:49.888: (44:49.888)$40,$58,$51,$12,$43,$C2

When you changed T3 to 200ms, that stopped the timeout occurring because all frames are arriving within 200ms of the previous frame.


To figure out what is happening when you switch on the ignition can you please do the following:
Set the View->Serial I/O option.

With ignition off, select Aldl->Listen to chatter
Stop after about 10 seconds.
Copy/Paste the output so I can see it in this thread.

Select Aldl->Listen to chatter
Switch ignition on (while listening to chatter).
Stop after about 10 seconds.
Copy/Paste the output so I can see it in this thread.

Wait 20 seconds
Select Aldl->Listen to chatter
Stop after about 10 seconds.
Copy/Paste the output so I can see it in this thread.

Thanks a lot for the help.

Timer settings tried
0, 0, 100, 0, 10, 50
0, 0, 200, 0, 0, 12
