1227165 is the service number.  It is a P4 ECU.  '89 is the last year
for the 1227165 in the Vette and Camaro's.  Try searching thru the
archives at:

http://www.diy-efi.org/diy_efi/asearch.html

(this will not work probably for a couple of days due to new server and
broken links)

It is an extremely useful resource.
