Three Ecus or actually 4 to choose from. P13 which is the oem, p28/p72/p06-p28 conversion but those need to be chipped with a basemap.

knock sensor and vtec solenoid needs to be run otherwise you can reuse the original harness.

if your's is a A1-A4, you'll also need to add the secondary butterfly switch vacuum box thingie.
