swapping a jdm b18c gsr motor into my civic EX and my knock sensor broke will this hurt my smog? do i also need to run usdm ecu/intake?


other question- i heard you have to re-wire for the butterfly to work on the stock gsr manifold anyone know how that works?

 

smog in so-cal=

 

yes you need a knock sensor because it might throw a cel for that and if ur car is obd2 then yes you need a obd2 usdm ecu..

you need to run wires from the IAB(butterfly) to your ecu

it's obd1. dam what kind of wires to my ecu? doesnt jdm b18c already have the butterfly setup on the ecu to open at 5750?

 

first what car is this going into? everything has to be in good working order. the ecu has to be a usdm ecu, and you have to get the butterflies wired corectly

intake should be stock but if not it has to have the eo number for your year engine.

 

find the correct gauge wire and length, connect it to a plug for the IAb and run that straight to the ecu for the butterfly
