Anyone ever thought of hooking up a LED light to your knock sensor? Is it possible on the SR20? Sounds like it would be exremely helpful when running lots of boost. I saw one for an eclipse on ebay: (http://cgi.ebay.com/ebaymotors/aw-cgi/eBayISAPI.dll?ViewItem&item=545144165). This one works throught the ECU, lights up whenever the ECU hears a knock from knock sensor. Wonder if it's possible to rig one up for an SR20??? Hmmmmm...
