EFIE's, MAP/MAF, O2 sensor enhancers??

[jcbarton]

Are all of these basically the same just that some cars need one or the other? I know a lot of newer cars require a MAP/MAF sensor. I have a 87 pathfinder with fuel injection but no MAP or MAF. I have been told I need an 02 sensor enhancer, is this true?? I guess whats the difference between the 3? Thanks

EFIE's are O2 enhancers(ENH), wich are alittle diff from a MAP ENH, but function near the same, but not interchangable.
