California emissions compliant (CARB EO D-742-3), which allows this product to be used on street vehicles within the USA.

What is a CARB FlashPro?
A CARB FlashPro is a FlashPro which only allows uploads from calibrations which are determined to not alter the any emissions related parameters in the ECU.

What does CARB stand for?
Not carburetor. 'CARB' is the common term for the California Air Resources Board, who are responsible for determining if calibrations could affect emissions.

Why should I use the CARB FlashPro?
Within the USA you must use the CARB FlashPro for any emissions controlled vehicle.

But I don't live in California / my state does not do emissions tests.
It does not matter - the concept of '# of state legal' is not longer valid.  Under the federal Clean Air Act administered by the EPA it is not legal to change any emissions equipment (including the ECU) on any emissions controlled vehicle.  There is no mechanism to prove to the EPA that an ECU modification does not affect emissions, but the EPA will accept the California Air Resources Board approval. Hence California legal modifications are also federally legal.

What if I sell by vehicle and wish to use the FlashPro on a competition vehicle?
The CARB FlashPro cannot be changed into a Race FlashPro.
Sell the CARB FlashPro and purchase a Race FlashPro from one of our Authorized Dealers!

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.

Do I need the laptop in the vehicle to reflash the ECU?
No. The FlashPro can upload either with or without a laptop.

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?
The FlashPro must be unlocked by the seller. Have the seller send you this screenshot which shows the serial number password and lock status. Hondata does not unlock FlashPros. The reason for this policy is to prevent both fraud (against us) and theft (against you).

Technical Notes:

This FlashPro allows limited tuning or preset calibrations.  For competition vehicles we recommend the FP-16CIVIC-L15T-US FlashPro as that FlashPro allows full tuning.

This FlashPro can only be sold to US/Canada addresses.
