95 xlt 4x4.....OBD or EEC
I've been reading some posts referring to EEC and OBD, and since my other Ford was an 83 it had neither and I need to learn up on this new stuff. Which system would be on my 1995 F150 4X4 5.8L??

EEC and OBD aren't the same thing, they are related though.
95 and earlier Fords have an EEC-IV (Electronic Engine Control, series 4) which includes OBD-I (On-Board Diagnostics, Stage 1) OBD-I is not at all controversial and creates zero problems for hot-rodding the engine, look at the 5.0 Mustangs.
In 1997 all vehicles were required to convert to OBD-II for smog control reasons. OBD-II monitors a lot more things and will throw error codes more readily when it runs up against a modification. You still can modify engines with these controllers but it takes a little more knowledge and/or work.
In 1996 Ford swithced to the EEC-V series PCM (Powertrain Control Module, i.e. computer) to include and implement the OBD-II requirements. Some 96 models have only part of thr OBD-II protocols, some have most or all.

seems like these days people are getting custom chips for ODB-II tailored to thier mods..
then it whines less, and gives a better spark/fuel map.
either one works.. just another $300+ to do it with eec-v
I doubt EEC-V does ANYTHING practical better the EEC-IV.
hmmm.. 94 stang, new body style, 5.0, eec-iv... huhmmmm that sounds like a cool car. (saw one yesterday.. had the 5.0 decals on it from an early 90's stang, but was a 94 5.0 fox, lowered and all..very cool)
