Ive got a 5.7 from a 2000 trans am. its been stripped of everything (seen here) http://www.ls1truck.com/forums/lsx-t...6-obs-4wd.html

Ive pulled the ecu intake TB injectors and fuel rail from 5.3. With the 5.3 ecu should i be using all the involved sensors for the 5.3 or for the 5.7?



I havnt started to cross reference part numbers to see if any or all are the same. I know the IAT is integrated in the MAF for the 5.3 so ill be needing to pick up on of those.

i learned quickly working with VW's that 2 sensors may look identical but operate in a different voltage range, and if mixed up can appear to operate properly when troubleshooted but is sending all the wrong signals to the ecu.
