This dyno is of a stock RDX with Stage 1 and Stage 2 performance tunes.

Stage 1 operates in all 4 dynamic modes and delivers a 10 hp increase everywhere.

Stage 2 is configured for Stage 1 performance in snow and comfort and Stage 2 performance in Sport and Sport + modes. Stage 2 delivers 36 lb-ft more mid range torque and 28 more mid-range horsepower for a much more exciting drive. 

The dyno figures are lower than the Accord turbo due to our four wheel dyno reading 10% lower than our 2 wheel dyno, and the AWD drivetrain absorbing more power. This leads to about a 20% torque and power difference from the 18 Accord. The midrange percentage improvements (15%-19%) are similar.

We've put together a series of training videos to describe the function and use of the FlashPro. View the videos in High Definition Full Screen to view the screen shots.

FlashPro Introduction

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.

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.

What is the difference between a reflash and the FlashPro?
The FlashPro is tunable by anyone.  All of Hondata's reflashes are available on the FlashPro and can be installed through a participating Acura or Honda dealer or through one or our many dealers.

How much power will the FlashPro make on my car?
The FlashPro for the 19 model RDX comes with Stages 1 and 2 calibrations. Power gains are listed on the dyno tab above. FlashPro manager tuning software allows custom tuning for different fuels and turbos. 

Do I need dyno tuning?

No, not on a stock vehicle with the with the supplied calibrations.

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.  At least a desktop computer running Windows is required.

Can the FlashPro be used on more than one vehicle or be used on different types of vehicles?
The FlashPro can only be used on one vehicle at a time. You can unlock the FlashPro by returning the ECU to stock, and then transfer to another vehicle of the same type.  A RDX FlashPro cannot be used on an Accord or Civic for example.

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.

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?

Follow these instructionsThe FlashPro must be unlocked by the seller. It must also be for the type of vehicle you own. For example you cannot use a Civic FlashPro with a RDX. Have the seller send you this screenshot which shows the serial number password and lock status.

Owner feedback

Thank you for whatever you did to my 2019 RDX! You transformed it from a “mom-mobile” to a fun to drive sports car! I liked the features of my 2019 RDX, but driving it was rather boring and disconnected. It accelerated when it wanted to and it was really tough to stay engaged while driving it. Now I LOVE driving it – THANK YOU SO MUCH!!!!
