Hey guys!!! Just finished my build on a h23 vtec with type s pistons. Project is completed and car is running. Problem #1: I keep getting code 23 which is for the knock sensor. A friend told me that its because im using the h23 wiring harness and ecu. He also said that the h22 doesnt carry a knock sensor. Dnt know how true it is but.....thats y im here seeking help. he told me to plug in the knock sensor into the harness and tie it off somewhere safe. Because of this knock sensor prob, the engine seems to bog in high rpms after the code comes up. Any info guys? Problem # 2: Im using the h23 ecu to run the h23 vtec, so that means vtec is not gonna activate. Im planning on purchasing a hondata in the future but right now funds are kinda low due to money put into the project. I got me a msd rpm activated switch from a friend but im not sure how to hook it up. Ive got the relay and everything required for the hook up. Can anyone help me out plz?
