I'm excited to announce that thejdm is now updated to the latest phpbb 3.2 software. You may notice the site is now mobile friendly but with the upgrade comes some hiccups. theGarage, theGallery, theArcade are no longer supported. In due time the developers should be working to release the modifications to work on the new software. #LetsMakeForumsGreatAgain
Knock sensor?
not just the v-tec's have them. my h23 has one also, trust me i spent $150 on a new one last year and spent a good hour trying to get the old one out considering it sits under the IM and unless you take off the IM you have to jack the car up andgo from underneath and reach past the header/filter/wiring harness to get to it(atleast omn the H series, pretty sure its the same for all though...
