    ECU Removal & Serial Number Location
    The ECU is located in the passenger's footwell. The kick panel is removed after depressing the centers of three small plastic buttons around the front covering panel. Unplug the three wiring connectors and remove the two front most 10mm locating bolts, plus the rear bolt. The ECU will slide out easily - if it does not, then check that the rear bolt has been loosened or removed.

    Shipping Explained:
    Once you purchase the reflash you will be emailed a couple of documents, so please put in a good email address or you won't recieve your paperwork. All orders have to be manually approved and that is done same business day or next day business day depending on when the order is placed. One document will be the form that Hondata needs so that they know what to do to your ECU, the other form will be the instructions on how to ship your ECU to Hondata and what you need to include in the box to them. Club RSX no longer offers the full shipping option. We have also streamlined the order process so that you no longer need to wait for the forms to be emailed, they are now emailed to you as soon as you have successfully completed your order. If you have any questions please do not hesitate to call Club RSX toll free at (866) CLUB-RSX and we will be more than happy to answer your questions. Your ECU is shipped back to you back to free of charge using next day air shipping from FedEx. Unlike other companies that make you pay for that, Club RSX covers the costs for you.

    Honda may not cover mechanical damage to the engine under warranty resulting from exceeding the factory red line. Hondata & Club RSX will not cover any damage as a result of installing this product.

5 out of 55 out of 55 out of 55 out of 55 out of 5 WORTH IT ALL AROUND!!!, 2.4.2010
Reviewer: Josh G. (Ventura, CA)
I was a little hesitant to purchase the reflash at first since I own a base model. the install was super easy, as I went to a shop just a few miles from hondata physical location. you can feel the difference in power and torque! I also have the greddy EVO II exhaust and AEM V2 intake, along with the reflash and royal purple oil, my base now puts down 200BHP(up from the stock 160) and somewhere around 170-172WHP, with much more torque than a stock K20A2 (I totally broke off a stock typeS on the freeway). the optional raising of the rev-limiter really helps to stay inside the power-band, and tho advertised to raise to 7300, mine will strech all the way to 7600 before it bounces off. I also purchased the gates racing serpentine belt, as my serp belt slipped off the pulley due to the extra RPM of the reflash causing my tensioner to need replacing, although I did have 119,000 at time of install. all in all, definitely worth it, as long as you have intake and exhaust to back it up!

with the hondata reflash the car picks up much faster, smoother and just feels more powerful. Its an upgrade you can certainly feel. higher revs are great and picks up at any rpm. having a base the car lags and although there is some lag still its not like it was before. If you plan on having a daily driver this is the modification for you. definitely worth the money. Go get it.
