Mitch | 02-24-2002 01:00 PM | Concerns with the HX lean-burn system Well, the main reason why I bought a HX is because it is my daily driver, My EF9 with a 100 octane diet is expensive. So anyway I am concerned with adding a intake,header,exhaust on the HX lean-burn civic coupe. It is the same as the EX, except for the lean-burn air/fuel mapping. I know that in closed loop the ECU should compensate for the air/fuel ratio, but it can only handle so much. My other concern is when it is in open loop the ECU is running a mapped program, which possibly could be too lean. I know using premium fuel will help. I was just wanting to know if anyone else has experience with this system and adding intake/exhaust components. Any guesses, thoughts, and educated answers would be appriciated. Thanks |
