    FlashPro features

    2016+ Software editing

    Hondata is the world leader in tuning Honda  engines and have many world records to prove this. Every map listed here has been comprehensively tuned for fuel, ignition and boost.

    Listed here are dyno plots of several of the many base maps provided with the FlashPro. 

    How the FlashPro will perform on a stock Civic 1.5 Turbo? The answer is superbly!

    With a 100% stock 1.5 Civic Turbo you will benefit from:

    • Improved turbo spool
    • Raised boost limits
    • Better throttle response
    • Better mid range power and torque
    • Removed speed limit
    • No change in part throttle fuel economy
    • World Class Datalogging - which will teach you a lot about your engine.

    Base maps:

    These are examples of the base maps provided with the FlashPro. The lower curves are done with the specified 87 octane on a stock 1.5 turbo Civic. The higher power curves are with California 91 octane and the FlashPro base maps.  With higher octane fuel and more boost, extra power and torque is easily achived. Maps for cold air and short ram intakes are also included.

    Civic MT 9 psi more boost with 91 octane  (this may cause the stock clutch to slip). 

    Civic CVT high octane plus 6 psi more boost.

        +25 HP and 35 lb-ft torque

    Civic CVT high octane plus 3 psi more boost.

        +15 HP and 14 lb-ft torque

    FlashPro getting started


    This video covers the installation the FlashPro Manager software, the USB drivers, software registration and upload of a calibration.

    Live Tuning

    One of the latest features added to FlashPro, live tuning gives you the ability to tune your Honda or Acura on the fly without switching off the engine. Live tuning simplifies part throttle tuning and significantly reduces the time and cost of tuning your car.

    Race Calibration

    Hondata has developed a Race calibration which allows you to tune with the MAP sensor and bypass the limitations of the AFM sensor. A look at the tuning principles for forced induction on a modern return-less fuel system.

    Datalogging and Air fuel ratios

    A look a the extensive datalogging capabilities of the FlashPro and the many ways in which to examine your engine data. We touch on the datalogging of the air fuel ratios and how you can use it to adjust your tuning.

    The FlashPro uses software called FlashProManager for tuning & datalogging.

    Online help is available.

    How do I tell if my FlashPro supports Bluetooth?

    From July 2013 some FlashPros shipped from Hondata including Bluetooth.

    From Jan 1 2014, all FlashPros shipped from Hondata include Bluetooth.

    FlashPros sold before the dates in the table below do not support Bluetooth. To confirm if your FlashPro supports Bluetooth follow this procedure:

    • Launch FlashPro Manager
    • Plug in the FlashPro to your USB port.
    • Press the FlashPro button, tab, then hardware.
    • If Bluetooth is present, Yes will be indicated.
    • If you do not see 'Bluetooth present' at all, then you are using an older version of FlashProManager and need to update.  This does not mean that you don't have a FlashPro with a Bluetooth radio.
    • If 'Bluetooth present' is No, your FlashPro does not have Bluetooth. You may upgrade your FlashPro is you wish.

    What is the difference between a reflash and the FlashPro?
    The FlashPro is tunable by anyone.  Most of Hondata's reflashes are available on the FlashPro as one of the many default calibrations available.

    How much power will the FlashPro make on my car?
    The FlashPro itself does not make power. The combination of parts and your engine makes the power. The FlashPro allows you to tune the correct cam angle fuel and ignition your car needs. The base maps are a great place to start though. The Maps page lists the calibrations available with the FlashPro and the power made compared to a stock Civic Si. Take a look at these dyno charts from our dyno day on a number of modified Civics with stock ECUS compared to a base map from FlashPro.

    Do I need dyno tuning?
    It shouldn't be necessary for common part combinations (intake, exhaust), but you still have the option of custom tuning if you wish to get a little more. Camshafts and race headers probably will need tuning to get the most of the them - it will depend on the manufacturer.

    Can I get rid of the AFM?
    You can switch to a MAP based calibration (recommended for forced induction and/or cams). You need to still physically retain the AFM because it also contains the IAT sensor.

    Will this work on more than one vehicle?
    The FlashPro is locked to one vehicle. It can be unlocked and transferred to another vehicle by returning the ECU to stock.

    Can I share the calibrations I make for my car?

    Do I need the laptop in the vehicle to reflash the ECU?
    No. The FlashPro can upload either with or without a laptop.

    How do I buy a used FlashPro?
    Follow these instructions

    Is there a VTEC window?
    Yes. This means that VTEC will operate based on rpm and engine load. For example, the supercharger reflashes have a VTEC window from 3200 rpm - 6000 rpm. At full throttle, VTEC operates at 3200 rpm. At light throttle, VTEC operates at 6000 rpm, and for load between full and light the VTEC will shift between 3200 rpm and 6000 rpm.

    So does that mean 1 unit Hondata FlashPro can only work with one ecu or car only? Which means I can't buy one FlashPro and use it together with a few of my buddies Civics?
    One ECU and vehicle at a time. You can unlock the FlashPro by returning the ECU to stock, and then transfer to another vehicle.

    Any option of immobilizer control?
    The immobilizer can not be disabled. We've implemented a number of features designed to protect the owner of the vehicle from theft, and one of these is not to allow the immobilizer to be disabled. This is going to be much less of an issue than previous products because the ECU does not need to be removed / swapped.

    If the ECU had been reflashed by another maker, can FlashPro still work?
    Probably - we could tell you based off the ECU part & serial numbers plus the calibration ID. When you unlock the FlashPro it will only be reflashed back to a stock calibration.

    Can it control nitrous?
    No. However, you can at least control the ignition timing to make nitrous safer.

    Will dealers need a software license?
    No. Every FlashPro will come with the full tuning software FlashProManager.

    Do I need to send my ECU to Hondata?
    No. Your ECU does not need to be modified for FlashPro.

    I am considering purchasing a used FlashPro. What do I need to do to check?
    The FlashPro must be unlocked by the seller. Have the seller send you this screenshot which shows the serial number password and lock status. Hondata does not unlock FlashPros. The reason for this policy is to prevent both fraud (against us) and theft (against you)

    How does the FlashPro work with my  FN2 GroupN ECU /  FD2 Civic Type R ECU

    The FlashPro will lock to and work with the FN2 GroupN  / FD2 Type R ECUs perfectly. However if you unlock the FlashPro for sale and return to stock the GroupN ECU will be returned to a stock US Civic Si ECU. In this state it will not work in the Euro and Japanese Type R Civics.

    How does it compare to KPro?

    KPro is a completely different product. It was created for the 02-04 RSX style ECU. It will only work on that type of ECU with the exact same Oki processor. Honda has changed the architecture of the ECU, including ECU architecture, processor and encapsulation, so that there is no way the KPro can be made to work on any other ECU.

    K-Pro requires the ECU be sent to a Hondata for the installation of the K-Pro daughterboard. By comparison, new FlashPro owners need never remove the ECU from their car.

    Because FlashPro is a different product from KPro, it has different features.  Not all features implemented in KPro are possible with FlashPro.  We will try to develop more popular features as time permits.

    In the meantime, if you run nitrous, you will be able to run a calibration that is far safer and make more power than you would with a stock ECU.

    Can I used a FlashPro for an engine swap into an earlier chassis?

    Unless the chassis is substantially the same as the donor engine (eg 2007 engine in 2006 chassis of the same type) we do not recommend that a FlashPro is used for an engine swap.  The KPro should be used, with 2002-2004 engine harness, ECU and transmission speed sensor.  The throttle body should be swapped to a non DBW type.

    Can I upgrade my older FlashPro for a Bluetooth enabled model?

    Yes. For $150 + shipping (around 20% the cost of a new FlashPro), Hondata will upgrade your old FlashPro and give it a 1 year warranty. Download the upgrade form.

    Civic X FlashPro owner feedback


    Yup definitely one of the best mods you can get right now. Forget the intake, exhaust, bov or whatever rice stuff. This is the best bang for your buck for power.

    FlashPro at 20-21psi i can get 5.7-6 seconds 0-60

    Still getting 30-47mpg on the highway depending how many hills I got to climb


    What won me over initially was throttle response and how much more torque the car had. The moment when my foot went to the floor on the gas, the first thought was, "Oh shit!" and honestly was surprised it was the same car I have except properly tuned. (Hellooooo wheel-slip  ).


    Oh yea it hauls some ass for sure.


    It's like night and day.


    Let me tell one thing...it pulls HARD on the street wow!


    The car sits you back in your seat and the traction control kicks in under full throttle bc the tires will break loose as max boost hits. Maybe its the cool weather helping it lose traction but it doesnt do that on the stock tune. And it feels effortless for this car to pass at freeway speeds when giving it some gas pedal.


    The quickest 0-60 time I've been able to pull using the torque app was a 6.3... I feel a huge difference between stock and using the flashpro.. It pushes you back in your seat


    There's a dramatic difference in acceleration. 40-90mph took about 7.4 seconds (flat road), compared to 10 seconds stock.


    Just got my FlashPro and loaded a basemap 6 PSI boost with Injen CAI. Wow, feels like a different car. Big gains!


    I have put it on my Malaysian 1.5T Civic and managed to achieve a new top speed (of 268 kph) on the dyno. no more getting stuck at 207km/h on the highways anymore.
