Holden VS V8 Commodore EFILive can't connect

[SPArKy_Dave]

Hi Guys,

I'm trying to get EFILive V4, to connect to the ECU in my VS V8 commodore.
I'm using the vehicle definition file - gmh-vr68vs8.xml.

I'm not sure if I'm doing something wrong or not.
The cable I'm using, was sold as being specifically manufactured for connecting EFILive to VR/VS Holden Commodores.


Here is a cut and paste of a few pages of the text log. (can attach text file instead, if that's easier to interpret) - there is alot more along the same lines.

Cheers,

David

The checksum failures point to faulty hardware. It may be any of...

• Either the interface cable circuitry is faulty.
• the wires in the cable may have a tiny intermittent fracture.
• the ALDL plug/socket combination is not contacting cleanly. The pin receptors in the socket may have been forced too wide by other/larger pins from another device.
• the wiring from the ALDL connector to the ECM may be faulty.

Ok, I tried to run EFI Live V4 again, and attempted to connect.

I first attempted to connect with Key on, Engine Off.
The Macro screen displayed the following data log over and over, with very few red error lines -

(I did notice however, that no values became active on either the aldl screen or on the dash screen.)

After letting the above chatter occur for a while, I started the engine. (started no probs)
With the engine running, I noted that quite a few red error lines started occuring, and eventually the connection would drop out.
I could re-connect easily though.
Unfortunately, even with the chatter occuring, and engine running, neither ALDL or the Dash, displayed any live values at all.
Re-starting V4, didn't help.

This is some of the log, which occured with the engine running -

As per my first post,
the vehicle is a stock standard 1998 series 2 VS Commodore ute, with a 5ltr V8 Engine.
I'm running V4, using the vehicle definition file - gmh-vr68vs8.xml.

Am I doing something wrong with the EFI Live program?

My original comment is simply reinforced by your experimentation. It appears that with the engine off the data is being received with no checksum errors. That is most likely for one of two reasons:

1. There is no electrical noise/interference on the ALDL bus.
2. There is no mechanical vibration causing marginal connections or wires to fail.

Once the engine is running, both of those conditions are lost and the system becomes electrically noisy and the wires/connections are subjected to mechanical vibration. Both of which can lead to faulty data transmission and checksum errors.

To verify if the problem is with the vehicle or the interface/software, try your same interface cable and software setup on a different 5.0 VS Commodore.

Paul

looks like a problem with the laptop, cable or car. In the first parts of your first log it looks like its receiveing a few frames ok then later on it doesnt receive anything...
