We can only reflash ECUs with a working ECU/immobilizer/key combination. Because of this we cannot reflash PRA, PRC, PRD or PPA ECUs.

Notes:

  1. If this ECU is used with a 6 speed transmission, reverse lockout will not work.
  2. PND A5# can be used only with Automatic transmissions and only reflash programs are available for this ECU.
  3. Use of this ECU is only recommended for motor swaps, as we do not offer any programs for the CRV. 
  4. This ECU does not use a wideband oxygen sensor and is not compatible with US or JDM vehicles.
  5. Only Manual ECU's can be used with the K-Pro
  6. PRB-A13 ECU's are not reflash or K-Pro compatible (2005 RSX).
  7. Nitrous features will not work with this ECU.
  8. PRA can only be used in European vehicles by European Dealers.  Not for use in any other situation.
