"This Software also gives a fuel economy improvement for all WK/WH/XK vehicles."

I figured this meant that it was for all engine types and the other part applies towards the 3.7

Agree it's only for the 3.7. At the dealership now and they advised it was only for the 3.7 engine.

Is this for all years, or just 07-08?
