Training videos

Hondata has put together a series of training videos to describe the function and use of the FlashPro. Some of the videos were shot using pre-release software. Some displayed functions have changed slightly. View the videos in High Definition Full Screen to view the screen shots.

FlashPro Introduction

Hondata's new generation programming tool for the TSX.

FlashPro Getting started

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

Live Tuning

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.

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.

Questions and Answers

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

- Does it improve rev hang?

Yes. Revs can be programmed to drop sooner after gear change on MT models.

- Are there base calibrations?

Yes, for common US intakes and injectors ranging from 310-1300cc.

 - Can it eliminate the second o2 sensor?
Yes. The secondary oxygen sensor is used to monitor the catalytic converter efficiency and assist with closed loop operation. For off road racing use in which a catalytic converter is not desirable, the secondary oxygen sensor can be disabled using the FlashPro Manager software without any negative affect on the tuning or operation of the car.

- 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. Dyno tuning is highly recommended for forced induction.

- 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.

-Will this support a 64-Bit Windows Vista and Windows 7?


- 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 FlashPro Manager.

Customer Questions


in layman's terms your sayin plug this in the obd2 plug and select aftermarket intake and exhaust system and it will automatically tune the computer for those upgrades?


What you do is plug the Flashpro in to the OBD port, plug a laptop into the Flashpro, and then you can choose different tunes from the computer to upload to the Flashpro.

You don't choose mods persay. You need to select the right tunes for the parts you have, or get a custom one.

There are going to baseline tunes in there for a few different common combinations to get you started without needing to visit a dyno.


I have a 2015 accord auto v6. I have injen cold air intake and Magnaflow cat back. I plan on buying the RV6 j pipe and HFPC's along with your 3.7 Acura intake manifold and throttle body and your Acura upgrade injectors. Will this Flashpro be able to optimize all this, or would i be better off having dyno tuned.Thanks.


A Flashpro is not a replacement for a dyno tune; it is a tool used to tune the car. In other words, without a tuning tool like a Flashpro, a dyno tune is not possible.


Hi All: Can you tell us what baseline tunes will be available in the package we buy for "off the shelf" for common intakes (CAI) and exhausts (Takeda, etc.)? Many thanks.


There is typically one main baseline tune that is good for mildly modified street use. The specifics of the bolt-on mods is not really important, as this baseline tune is good for most all you could be doing, including not having any other mods at all! Once the modifications reach a more aggressive level, such as booting or new camshafts, the custom tune feature will be used and the baselines will be obsolete.

Q:Has there been any news on the 2016 Accords being supported?

None yet, unfortunately. At this time the best best is to go with a KTuner End User flash kit.

Q:I have a accord 2013 v6 touring Automatic, but the serial number of ecu end in 5G0-A65. It will fit the flash pro to my car? Thanks.

Yes this Flashpro is compatible with your ECU/car.
