This is for an ECU reflash - the ECU is not included.  Hondata does not sell direct - the reflash must be purchased from a Hondata dealer. The ECU reflash form must be sent with your ECU.

We do not recommend the use of nitrous or forced induction for this reflash. For these applications use the K-Pro.

What if you have modifications?

What will work well:

What is not recommended:

Check your catback exhaust carefully. The internal diameter of the rear muffler is often smaller than stock. If this is the case you will probably make less power than stock with more noise. It will work OK with a stock airbox but you will not see these advertised power gains, and you may feel a dip after VTEC.

If you have a race header you will run lean. This is not a result of the Hondata reflash. Even the stock ECU will run lean with a race header. If you intend to run race headers you have two choices:

  1. 05-06 RSX Race header reflash
  2. Hondata K-Pro for the 05 RSX.
