Other than getting the proper ECU the only other things that need to be done are:
perform CKF trick --> http://ff-squad.com/wp/?p=309 Add a secondary O2 sensor - this may already be done in your case. The car is at least wired for it, so it's simply a matter of installing an O2 sensor and plugging it in (you may need to weld a bung to the exhaust depending on what's on there now though) That should really be it, EX/Si models already have a fuel tank pressure sensor so you should have no issues there. As well both OBD1 and OBD2 B-series vtec ECUs look for knock so it should already be wired (unless you have a chipped ECU and it was disabled and never wired in) |
