AP1 ECU with AP2 motor
#22
Very common, I am/was a user of a 00-01 ecu with F22 for a lot of years. That ecu does run the richest and should require no tuning, however there is always an exception for someone who may be running a really efficient de catted exhaust system/intake, TB aka breathing mods on top which would make the fuel requirements go up, and of course the 02-03 ECU does run a bit leaner which would exacerbate this. I did run into that issue myself becuase of my level of breathing mods, and rectified it by ditching the stock fpr for an adjustable one (AEM makes a good one that goes in stock location) Turning up the fuel pressure is a simple and effective method of getting your afr back to optimum levels in Open loop/wot. Idle/partial throttle is in closed loop ecu operation an will self calibrate to the new fuel pressure, its really very strait forward. Best rule of thumb when going down this road is to invest in a wideband if you question your level of modification and get that verification that you are running within a safe afr window in WOT.

Is the wide band O2 sensor plug in compatible with the OEM ECU?
I thought the OEM ECU used a type of sensor that only sends out a binary signal.

It does not see the stock ECU. It is purely a stand alone system utilizing its own 02 sensor to the reference gauge. You can pick up the complete ready to go package from AEM (other then welding in the 02 sensor bung) for a little over $200. Oh and you need to put the gauge somewhere. Typically a pillar mount, or stick it on top of the dash in the corner.
