Hi Bruce, you're in the right place.  Do you know what ECM you have?  I
guess it's probably a 165 but I'm far from an expert.  To get some
background info, go to the diy_efi WWW page, click OEM systems, then
GM.  Look at everything there, esp programming 101, tuning tips, and
Ludis' home page.  Ludis' page can xref your car and tell you what ECM
you have.  Once you get your ECM part number you can search the article
archives for it and you might turn up some useful info.
