So Im going to attempt the knock sensor bypass on a 99 Ex coupe Im working on. Ive read a few articles and gathered most info I need to accomplish this. At one point someone swapped out the Y8 block with a d15b2, and of course there is no knock sensor on a d15 block or a CKF sensor. For those of you that have some knowledge w this bypass, it consists of adding a piezo transducer in place of the knock sensor. feel free to share your thoughts or knowledge. If all works out well, I will ad a tutorial write up to this thread.
