As stated in my other post, I am doing a mini-me swap on a 93 Del Sol. Well anyways, I am using a p61 ecu for this. The p61 is set up for a b17 w/ knock sensor. The d series doesn't have one. I was wondering if the knock sensors are normally opened or normally closed to ground. If they are n/o, I should be fine leaving that pin blank. If they are n/c, I will need to run a pin to ground to prevent the timing from being retarded. From looking in my Integra Helms manual, it looks like it is n/o. I just wanted to know for sure.
