put my 89 eec in started the car it loped like a 5.0 with an oversized cam 10 times too big - and it wouldn't idle - then I smelled an abuntant of gas so I turned it off and scratshed that... it runs WAY under par with the damn hypertech chip in it, when I take the chip out and have the regular 91 eec in it it misses/backfires and seems like its running on 5 cylinders. So I am led to believe that the hypertech chip may have re-burnt the eec and therefore the computer is looking for the hpyretech chip and it can't find it... the best air/fuel ratio is with the hypertech - but even that you know its way off - I think its running lean... 89 eec ran so rich it made my eyes water... ooh this is frusterating. Anyone know how to reprogeam an eec for oem specs or erase everything (not d/c the battery or taking the eec fuse out)??? could ford do it??
