Okay, I down loaded th ebuild guide from the gm performance web site. Inside the chapter of "Engine assembly stock to 250hp" it gives you the part numbers for the reflash for both automatics and manual. So here they are: 12590819 for automatic transmission /
12590820 for manual transmission. This is straight out of the ECOTEC Build Guide. So if anyone is having trouble getting the reflash numbers now you should have them, unless they have changed them since the guide was published.

Git er' done!!!!

that is just a part # , dealer still has to call to get VCI #

not to mention if you take that number to parts it comes up as
" not found in master GK catalogue"

noble effort though

The link to look up your VCI number from your VIN no longer works.... too bad

Oooh... look what I found

I don't have my VIN handy to check if it works or not tho....!

I have my VIN numbers but ahere at work the computers will not support the web site. So that will have to wait until I get home. But I think that it may give us something.

This is what I just found out. I got it to where this computer would accept the scripts froom the website. It gave me these numbers for the PCM/VCM:
Part Number Cal.ID# CVN Description
12598563 12598565 N/A New calibration to ensure proper catalyst monitoring at idle.
12593508 12593510 N/A Control module calibration
So I am guessing that it worked, these would be the Cal ID for the reflash for my specific car.
