by having that check engine light for the IAT sensor, does it make my car performance go down? or does it matter if its hooked up or not? where can i get a sensor at? is it on the intake tube off 96+ civic? and where will i hook it up to? can i get some pictures of your d16y8 swap of where the sensor would go? do i still need it if im going to boost? thanks guys.

 

what ECU are you using?
It matters.

 

i am running 89 si ecu. pm6
