EEC's & Calibration Codes

    The Dealer has told me that there is no difference between the 84-85 Mustang & LTD-LX  EEC's.   Altho the PN's are different, & the 85 Mustang has 10 more HP, he may have been referring to rebuilt, replacement units!

    Have tried all three, Mustang, LX & Police & have found no real difference between them on the street.  May test them at the Strip or on a chassis Dyno some day.

     Haven't found anyone who has "improved" the CFI  EEC.

    Wonder how a Lincoln LSC  EEC would work, may check it out someday.

Look for the Cal Code on the Left  Valve Cover's Paper Label up to about 87, after that it may be on the Drivers door pillar..
