• Existing ECU used - nothing to change and factory immobilizer function remains unchanged
• Fuel and ignition tables optimized
• VTEC engagement optimized for increased midrange
• All factory functions such as gauges, OBD2 compliance, and factory tools including scan tools remain unchanged
• Program may be reverted back to factory tune at any time for a small fee ($75.00).

ECU programs available:

• Program A: for stock or mildly modified (intake and exhaust)

• Reflash is available for 2006-2008 Honda S2000s only (ECU code 37820-PZX-A09 through A14 and 37820-PZX-A21).
• This is NOT compatible with 2000-2005 S2000s which do not use flashable ECUs and are not compatible with the 06-08 ECU.
• These tunes are not able to be modified. If additional tuning is required, a programmable ECU should be considered.
• If you start with Program A, and add a header at a later date, you may upgrade to Program B at a reduced cost of $200.00 (please contact ScienceofSpeed).
• Reflash requires the removal of your factory ECU to be sent to Hondata for programming. Upon purchase, you will be provided a pre-paid shipping label and form to send with the ECU. Price includes standard shipping - overnight is available.

• On the day of order (by 2pm) you will receive a pre-paid shipping label and form by e-mail to send your ECU in.
