    Will It Fit Your Vehicle?


    Hondata now offers a reflash for the 1.5L turbocharged Civic.


    • Turbo spooled 500 rpm earlier
    • 4 to 6 psi boost increase from 3000 rpm to 6000 rpm
    • 20-28 hp increase from 4500 rpm to 6000 rpm
    • Fuel and ignition optimized
    • Partial throttle fuel economy unchanged
    • 91 octane tuned

    works with ECU part numbers:

    • 37820-5AA-A55 to 37820-5AA-A65
    • 37820-5AA-L55 to 37820-5AA-L66

    Tuning notes:

    The CVT equipped Civic is extremely difficult to dyno. The % torque changes on this graph are accurate, but due to the variable gear ratio of the CVT, the absolute torque number is incorrect. Power figures are correct and approximate crank HP. We will update these charts when a MT turbo Civic is available.

    The yellow line in the charts below indicates the average performance through the areas where the CVT is trying to establish a gear ratio. Hondata has limited the average peak mid range torque in this reflash to approximately 7% over stock to retain good CVT durability. The Hondata re-flashed 1.5 Turbo Civic is far more responsive when needed, but still retains its excellent economy when driven with restraint.


    You are responsible for paying for and sending your ECU to Hondata. You can send your ECU as fast as you would like and shipping costs normally start at $10.00 for ground and $60.00+ for next day air. We recommend using an express service (2 day or next day) through FedEx or UPS because they have the least amount of delivery problems, provide proper insurance, and have good package tracking. We recommend that you do not use USPS because of delivery issues. You are not sending your ECU to K Series Parts you will be sending it to Hondata directly and we provide all of the instructions on where it needs to be sent once your order is approved.


    After we approve your order we will send you two emails, one email will be a Hondata form and the other email will be instructions for shipping and what items need to be included. Orders submitted by 3:00pm Mountain Standard Time Monday to Friday are normally approved same day. Orders places after 3:00pm MST or on Saturday and Sunday are processed the next business day.

    Hondata normally reflashes ECU's the same day they receive them but they do get busy and it might take an extra business day. We recommend that you plan on a 3 day total turnaround time from the day that Hondata receives your ECU.

    Return Shipping

    Hondata uses K Series Parts FedEx account to next day air the ECU back to you once the reflash has been installed. This means that you do not have to pay for return shipping. Your ECU will arrive by 3:00pm the day after Hondata completes the reflash installation. Hondata does not provide us with a tracking number or notification when they ship the ECU back to you.

    ECU Serial Number

    The serial number is located on the ECU. Hondata has provided instructions on how to remove the ECU.

    International Customers

    K Series Parts cannot sell reflashes to customers outside of the United States per Hondata request. The shipping address must be a US based address.
