Now available for the 2006-2011 Civic Si is the Hondata FlashPro! The Hondata FlashPro allows full tuning of the Civic Si directly through the diagnostic port. No physical modification to your Honda ECU is required!
The Hondata FlashPro is a hardware and software combination that connects from your laptop's USB port to your 2006 up Civic Si's diagnostic port. It enables you to tune your engine computer for engine upgrades like; intake, exhaust, header, cams, nitrous, turbochargers, and so much more!
FlashPro Manager software's advanced datalogging and live tuning capabilities combined with thoroughly tested base maps (56 included with software) allow your car to be tuned faster and more accurately than any other solution on the market. You will love the way your engine's response is improved.

Frequently asked questions about the Civic Si Flashpro System:
- What is the difference between the Civic Si reflash and the FlashPro?
The Civic Si reflash is incorporated into the FlashPro as one of the many default calibrations available. Rev hang has been eliminated and the ECU can be easily returned to stock.
- Are there base calibrations?
Yes, there are 56 starting maps tuned via the Air flow meter (AFM) or MAP sensor for all common part combinations, plus Greddy turbo, JR and CT superchargers.
- 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 basemap from FlashPro.
- Does it fix the rev hang?
Yes. The rev hang is the result of the injectors continuing to provide fuel for a period of time after the throttle is closed. This time is reduced by the calibrations provided with the FlashPro and the revs drop much sooner after throttle liftoff.
- 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 FlashProManager 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.
- 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.
- What about smog with a MAP calibration?
According to US and CA law the FlashPro is for off road use only. However, if you did smog with you would find the readiness codes supported and complete as long as your emissions systems are intact and working.
- 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.
- 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.
