hey i been looking around here and can't find a answer to my questions, will a obd2 gsr ecu work on a ls/ vtec with a b16 head, and yes i know it will need to be tuned. and what is 99 civic si head, obd2a or obd2b? thanks

 

with the right sensors any combo of those will work with the appropriate ECU...


96+ Civics are OBD2... a head isn't anything - the sensors and distributor used are what make it OBD0/1/2

 

ok thanks

 

you won't be able to tune anything on an obd2 ecu. You should be using an obd1 ecu that is chiped and running Hondata, Crome, Neptune etc if you want that setup to run properly.

 

oh you can't tune a obd2 ecu? i was gonna buy a obd2 gsr ecu and run a skunk2 conversion harness
