Unknown E67

[Lennart]

I got an E67 with Serv. No. 12603530 and part no. 12607559. Anyone know if it is any good? It does not show up in the compatibility list.....

Hi Lennart, haven't heard from you for a while.
The compatibility list is for the OS number, GM never print the OS number on the case so you would have to read out the tune first to know what it was. The actual service number 12603530 just sounds like an early 2006/7 E67.
