i have an ls/vtec setup. a 91ls block, and a 94 delsol head. im using the delsol ecu. my ecu is throwing code 23 (knock sensor) since integras didnt start having knock sensors 'til 96, is there any way to make my ecu disregaurd it? ive been told that i have to "chip" my ecu, but i have no idea what that means. im also getting code 2 which is heated O2 sensor. can anyone help me?

thanks

 

You could add and wire a knock sensor, but that is not cheap. You can chip the P30 ECU, which means that you replace the memory chip with a custom program. There are companies that do that.
