Most Honda vehicles starting from 1996+ have a stock immobilizer.
     A part of this immobilizer is located in the ECU which will make it
     difficult to change the ECU. (i.e. for replacement with a Chipped ECU,
     replacement for Repair, temporary replacement for trouble shooting,
     etc ...)
 
     To solve this problem, replace the immobilizer-board of the ECU with
     our Mobilizer Modul. With this the modified ECU will accept every Key
     with transponder (as long as the Immobilizer-Control-Unit under the
     dash sees the transponder, too).
 
     If you want to use a key without transponder, you need to bypass
     the Immobilizer-Control-Unit under the dash, too.
 
     For further detail take a look at the Installation Instruction.
