What is the difference between a reflash and the FlashPro?
The FlashPro is tunable by anyone.  Reflashes are not available for the FK8 Civic Type-R

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. Depending on the fuel, from 30-60 hp.

Do I need dyno tuning?
Some modifications, like exhaust systems, need no dyno tuning. FlashPro Manager comes with a variety of tunes for different configurations. Pretty much all you have to do is select a tune with the matching modification level you wish and drive. You still have the option of custom tuning.

Will this work on more than one vehicle?
The FlashPro is locked to one vehicle and will only work with a jailbroken ECU.

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

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 as long as that vehicle’s ECU has been jailbroken.

If the ECU had been reflashed by another maker, can FlashPro still work?
Probably, but since we do not know what changes have been made by other parties we cannot say for sure.

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?
Yes. From the factory your ECU cannot be programmed via OBDII and must be  jailbroken by Hondata.
