Those Holden Bins I uploaded are N.G.

I thought I wrote that info up, anyway, it's from a 1994 model Holden
Commodore (no VIN avail), with 5L V8 (Not a 305 Chev), 4spd Auto Trans. I'm
not sure on the PCM numbers but it has 2 plugs, a 24pin and 32pin, larger
than an 808, a P5 maybe?.

I found the checksum is stored at $6006+$6007, add all bytes from $5000 to
$FFFF then subtract bytes $6000 - $6007.

How bout Zipping that disassemble up and sharing?.
