I understand that there is an upgrade to my '04 PCM ZR6 ECM. I hear that it corrects intermittent idle "hiccups" that can occur and a general performance increase.

What is involved to upgrade the ECM to the latest version? Is it an in-boat flashing of the ROM or does it need to be pulled and sent to PCM and replaced?

Ha.... I think you and I might be the only ones on this site who care about this....

Think I'm gonna try PCM direct.......... My understanding is the upgraded ECM is ZR6 issue specific.
