Well guys, I may be a good source of information for this forum, but I learned everything I know from listening. For quite a long time after my swap, I was constantly fighting the knock sensor CEL code. I thought about cutting it out altogether, and in fact tried in a halfass way to do so, but the computer didn't like it. I have a decent amount of detonation sound. I have replaced my spark plugs, done and redone my valve timing, and done all the basic tune up stuff. I have replaced my air filter, and also ran octane boosters with my premium in twice the recommended amount. Retarding my timing has not decreased detonation, and at a certain point can actually make it worse. Here is a strange fact that the old veteran mechanic that I learn from taught me. Retarding timing too far can increase heat, which causes more detonation. On that hint, I advanced my timing, as a troubleshooting measure. Success in part, the detonation decreased, but did not stop. 15 deg +/- 2 is the norm. I have ran from 13-17 with detonation still. The Knock code which used to plague me, has not appeared in quite some time. It used to retard my timing a lot, and that didn't stop the ping, but killed performance. My car runs great. Pinging sound has been normal for a long time, can't hear it during VTEC, but it might be clouded by the increased noise. I use good gas, and have tried octane boosters. No codes in months. I haven't tried a extra ECU, since no one near me has an H22, let alone an auto. I haven't tried extreme advance of timing or a VAFC. I was told that the auto P28 application shouldn't be tried, since the P28 is standalone without a TCU for my auto tranny. Hondata is spendy, and I can afford a new engine if shit goes bad. Let me know what you think. I don't downgrade anyone for trying to help. Driver1, Recked, dohcvtec_accord, your comments would be well appreciated.
