How to tell a "fake" ECU from a real one

  1. halifaxhops
    There are a ton of fake ecu's out there two easy wats to tell at a glance are the height of the transistor, usally the fake ones are around 3/8" high and a real one 5/16 or so. Another way to tell at a glance is if there is printing on the transistor and also a insulating pad under it. Just two ways to tell. New ones are a real crap shoot now.



    Hope it helps.

    The only exception I have found are the RE hi rev boxes they have a fake transistor but are about as good as you can get now.
