The excelsior Henderson Super x also uses the Sagem MC1000.

This is the most complete tuning software available for the Sagem unit.

Do tell. Do tell. My ecu uses a siemens C176CR-LM. What algorithms have you seen used on a siemens?

My guess is that this algorithm is common across most oems that use the part. They make it...

Yes, I get a new seed every time. I posted the good seed/key pairs I have captured so far over in the iso area.

What is the best way to view what the application running on w2k is doing?

Just perusing these posts. I have the identical problem with a different ecu. I've posted stuff over in the iso programming area.

If you can gather enough correct seed/key pairs, my guess is that...

What is the best way to monitor the application? It is running on w2k.
TIA!

Hmmm... there is a 10 second timeout if the key i send back is incorrect, but i guess I could write some software and let it run for a few days until i build up all the pairs creating a big...

perl scripted these out of some captures:

Well, this "unlock" appears to be my last hurdle.

Did some looking around in the files portion of this site and this is described in section 6.3 of 14230-3s.pdf.

The 2A 6F is different each...

I'm trying to unlock a iso9141 segam ecu. The "xx xx" in the listing below is what I'm trying to figure out. This appears to be a response based on some transform of the "2A 6F" in the previous line...
