    I recently swapped an obd1 gsr engine (b18c1) into my 94 dx. I wired up the knock sensor but my p72 is throwing the cel code 23. Since I am 100% sure it is wired up correctly my only guess is that my knock sensor is no longer working. I searched and people said that everytime the knock sensor detects knock it pulls 3 degrees of timing and adds fuel until it no longer knocks. The question is how much timing does it pull if it is not working correctly. Does it just pull the initial 3 degrees? Also I went and checked on a price for a new knock sensor from Acura and it's like $140 so I was wondering if there is another knock sensor that will work. Many mr2 guys will just buy a GM 1 wire knock sensor and get a convertor that will convert it to the correct threads and pitch, suprisingly it will not trip out their computer. Has anyone tried anything like this?

    Also throwing in a chipped p28 is not an option because I need to get it B.A.R. certified.
