OK I JUST COMPLETED MY LS SWAP INTO MY 89 CIVIC DX....I GOT IT RUNNING FINALLY AND TEST DROVE ON THE WAY BACK THE DREAED ENGINE LIGHT CAME ON...CODE 12..EGR VAVLE...PROBLEM..92 LS MOTOR HAS NO EGR VAVLE I HEARD ATLEAST IT DOESNT...ANOTHER PROBLEM...RUNNING A 91 LS ECU...ECU LOOKING FOR EGR VAVLE CAUSING CAR TO IDLE ERRACTICALLY....WHAT WOULD I DO TO STOP THIS ANY WAY TO BYPASS EGR VAVLE????ANY HELP WOULD BE GREATLY APPERICATED...THANKS...

 

well since u used the wrong ecu i think u need to put a egr vavle on there should be a way to do it or by pass it

 

How did he use the wrong ecu? What is different from 91 and 92?

 

fuel mapping is different and so is the entire program since its obd1

 

i could proably use the 90-91 intake to gain a egr valve...right???
