Audi A2 1.4 Petrol ECU/cluster support #76

Open Sveshais opened 5 months ago

Sveshais commented 5 months ago

As a part of ECU swap procedure, I've been trying to read SKC from cluster or ECU, but with no luck. Log: KW1281Test.log

Is there any chance to add support for this ECU/cluster? Any more info or help I could provide?

@gmenounos I have access to this cluster so I can investigate if you wish?

gmenounos commented 4 months ago

I can find very little info online about how to retrieve the SKC from an Audi A2 cluster. However, maybe the A2 behaves like the C5. In that case, try this new release: https://github.com/gmenounos/kw1281test/releases/tag/v0.98-beta It will treat an A2 cluster like a C5 when using the GetSKC command. Please report back with the latest kw1281test.log file.

It doesn’t work. It stops on the second Sending Custom Login block with a timeout. I have a tool that can read it so I can sniff it with a logic analyser if you want

Yes, that would be great.

It actually works as is. It succeeds with “loginas9”. To get it to read I had to hold the RPM at about 2000 otherwise it was unstable. But there is a high chance that I’d just my cable being voltage sensitive.

@Sveshais do you want to try it?

Log from the latest version, failed with System.InvalidOperationException Expected block of type $72: KW1281Test.log

@dyneon are we referring to the same thing? I'd expect SKC to be a 4 digit code (5 with leading zero).
