vtismill Posted June 24, 2013 Share Posted June 24, 2013 I have just put a b18c engine out of an integra sir into my vtis and got the jdm p72 ecu too, I was under the impression it went straight in but the plugs are different? Thought they were both obd1 style plugs? Also how do I bridge the pins for vtec to work or does that not matter since its no longer b18c4??It's baffling me a bit any help would be appreciated thanks james Quote Link to comment Share on other sites More sharing options...

vtismill Posted June 24, 2013 Author Share Posted June 24, 2013 Thanks for replys Il try and put a picture up, that's a bit annoying, will it still work with a harness? Was sure it was off an early teg as well. Thanks all Quote Link to comment Share on other sites More sharing options...
