Yup, that's the one my car already has. That update came out around july/aug '10. As I understand, it primes the fuel pump prior to starting. Makes sense and has seemed to help.
I don't think my current issue is fuel pump related. I only had 2 replaced on my last car and it was fine after the update. I had issues with coil's, injector(s) and plugs.
