i just complete exactly what you want like 1 week ago.. you need to open you ecm and check if it has the internals that controls the IAC valve, check here: www.lt1swap.com
if your ecm does has the internals that controls the IAC valve then this is what i did:
on the tune file depot webpage i find a 04 or 05 GTO manual calibration, this one uses a 1mb ECM but still uses the drive by cable, then i did a full flash, then changue the parameters on the tune to suit your engine, like displacement, spark tables, VE tables ,, and it is runing just ok now
For quick reference - http://www.lt1swap.com/cable_conversion.htm
It took me a minute to find this great resouce explaining what is needed.
400ss does the gto tune fit the truck wiring harness?
EDIT -
The 1 MB GTO tune did not load into my '99 512k computer.
Used an automatic tranny truck tune with the automatic SES codes turned off. Works great.
