Hi All, it looks as if GM sold E38 ECM's as service part 12597121 for 06 & 07 cars using the E38's.
In 08 they seemed to switch to: 12612384 for all cars using E38's including LS3 and LS7 Corvettes.
Anyone have any ideas whether the hardware was changed at all?
I read another post that indicated that the throttle control subsystem may have been changed.......which then begs the question as to whether the pedal has changed also.
