Are you able to use a 96-98 ECU on a 99-04 engine/trans? I have an 02’ aluminum explorer 4.6 and 99’ GT T-45. Using a 99GT wiring harness
Are there certain ECU’s that are better or worse like fox bodies had?
Will the ECU cause drivability issues if there is no EGR/emissions equipment?
The only performance mods will be bigger TB/plenum, bigger maf, and shorties/full o/r exhaust

Very short answer. No. Why? For one the 1996-1998 model year uses coil pack ignition. Where as the 1999-2004 model year uses COP ignition.
