Training videos

We've 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 programming tool for the Civic Si / Acura ILX.

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.

 Can it improve the rev hang?

Yes. Revs will drop sooner after gear-change.

- Are there base calibrations?

Yes, for injectors ranging from 270-1300cc.

- What sort of power gains can I expect?
By way of example this car was baselined at the dyno with a test pipe, 06 Civic Si intake manifold and replacement air filter. All gains (35 hp) were made from FlashPro tuning.

- 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 will need tuning to get the most of the them - it will depend on the manufacturer. Dyno tuning is highly recommended for forced induction.

- What about smog?
According to US and CA law the FlashPro is for off road use only. However, if you did smog you would find the readiness codes supported and complete as long as all your emissions systems are working and the car is correctly tuned.

- Will this work on more than one vehicle?
The FlashPro is locked to one vehicle and ECU at a time. It can be transferred to another vehicle after returning the ECU to stock and unlocking.

- 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 64-Bit Windows Vista, 7 and 8?

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

- Will dealers need a software license?

No. Every FlashPro comes with the full tuning software FlashPro Manager.

    I rated the FlashPro 5 stars only because I could not rate it a 10. Honestly the best modification I have done to my car so far. Greatly improved driveablility (made that word up). Helped reduce and in some cases remove "rev hang", smoothed out VTEC crossover between shifts. The different base maps are helpful though they leave some room fine tuning. I'd suggest having a professional tuner do that though. On a side note, I regret not making this my first purchase for my car ('13 Si), maybe next time I'll listen.
