Ive spent a lot of time searching for the answers about knock sensor but couldn't find anything satisfying. First off I got a H22a1 in my 95 Accord.

Many Have said that they used the chipped P28 and a H22 basemap. Some have used it for performance gains, and some have used it just to get rid of EGR or Knock Sensor related problems.

Ive yet to hear someone explain as to how a chipped ECU is going to make some beneficial changes without a Knock Sensor reading? and what other ways can the PCM detect pinging or knocking and make compensation to timing without such sensor?

Im planning to get a ECU from our sponsor here so I just want some peace of mind.

 

Nevermind. I really dont think a beginner like me is going to find the answer just simply asking. I looked through here and found none. Maybe I was posting in the wrong section, or asking the wrong question. I really feel that these questions I asked are not the common ones. I went elsewhere for the answer. I went to my workplace. I've ran through a couple training modules before I asked my shop foreman some questions. According to the module, knocking happens when ignition timing is too advanced (that one of the reason, but definitely the one I was looking for). Other sensors like temp, map, and knock play a part in adjusting the timing. The only way it will adjust is retard the timing. that is why people opt to adjust their iginition timing close to the max allowable advance so that if it retards it will be within the recommended range. That means if Im scared that something may screw up, its best for me to go dead-on the recommended timing or retard my timing by up to 2 degrees to be on the safe side since I wont have a knock sensor telling the computer that its knocking. Now I think I know what the real question should be.

 

Your foreman is correct. Most people get rid of the knock sensors because you can judge detonation on a dyno to some degree, between a torque plot, and observing spark plugs. Generally speaking, you wont need a knock sensor.

All they do is retard timing in the event of a registered noise increase over a pre-determined threshold. Honda's are detonation resistant in most cases, and even pinging here and there wont immediately destroy your motor. You really have to be rather ignorant to the fact that its happening for it to do any real damage in any short period of time.
