I would like to know if a P73 ECU is interchangable with the stock computer. And if so will it be to hard on my motor if used with a V-AFC?

 

what year p73 ecu? connections might be different.. car might not run perfectly but it will make it run

 

i thought p73's were type r ecu's so all of them are obdII and they should fit on ur obdII b16

so yes im guessing it would run with that ecu...

 

depends on what year the obd2 ecu is.. some of the integra type r p73 ecus had immobilizers in them.. some were obd2a while some were obd2b..

in his case he would need an obd2b ecu that does NOT have an immobilizer built into the ecu.. he would need a p73 from a 00-01 ITR and im pretty sure they all had immobilizers, unless you get a obd2b-obd2a conversion harness....
