Check ECU Compatibility
To ensure that you order the correct FlashPro we recommend that you check your ECU is supported.
The ECU part number is located on the ECU. The ECU is located in the engine bay near the battery. You may need to remove a plastic cover in order to see the sticker containing the part number.

What sort of improvements can I expect?
Gains will depend on fuel type, suitability of bolt-ons and tuning. It is difficult to generate a consistent dyno graph for the CVT Accord, especially at lower RPMs. Above 6200 RPM ignition timing is lowered to reduce engine power for the next gearshift.

Hondata's new generation programming tool for the 06 - 09 US Civic Si, the Japanese 06-09 Civic Type R and the European 07-09 Civic Type R. A brief introduction.
FlashPro getting started
This video covers the installation the FlashPro Manager software, the USB drivers, software registration and upload of a calibration.
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.
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.
