	90-92 F-body (Camaro) used a ecm p/n 1227730 - which was also used in
J-bodied cars. About $50 in local wrecking yards. 86-89 F-body used ecm p/n
1227165 about $75. If ya use 730 ecm from J-body will need to replace eprom
or used F-body bin file in existing prom. A few weeks ago Steve S.
mentioned he had a circuit to adjust for any cam. Haven't heard any more
info from Steve on circuit. Hope he's reading these posts and will decide
what he wants for the circuit.
