I just stumbled on to this the other day and was wondering if anyone has tried this yet...I'm thinking about doing it.

Of course. Many people already have the reflash and love it. Biggest thing is that you need to have I/H/E or at least 1-2 of these aftermarket parts. Otherwise, you may loose power.

 

Heres some news about the reflash!

Hondata Announces Recall on '07 Civic Si Reflash
This recall only applies to US owners of the 07 Civic Si 2 or 4 door who have previously paid for a reflash.

The reason for this recall is that Hondata inadvertently installed the Canadian 07 Civic Si reflash which does not have the VSA (Vehicle Stability assist) function onto the 2007 US ECUs.

No other functions other than VSA are affected. No other reflashes other than the 07 Civic Si are affected.

 

^^^you didn't mention they'd fix it for free

"The recall procedure is this:

- Customer will fill out this form
-Customer will send the following items to directly to Hondata:

ECU
A signed copy of this form

On receipt Hondata will

- Reflash the ECU and return ship FEDEX overnight. Turnaround will be same day.
- Hondata will include a free K20Z3 heatshield gasket and refund check for $75."

it's nice when companies stand by their products. Hondata ftw

 

I'm getting my header and CAI in about two weeks, then i'm going to get the reflash.
