Actually, it does mention the '07 ECU by part number.

"Any 06 S2000 with the ECU part numbers found on the bar code on the side of the ECU:
37820-PZX-A09
We do not have a reflash for 37820-PZX-A11"

The -A11 part is the 07 ECU. Compare the following info (links below):

Illust-No. Part-Number Description Reqd.-Qty. Year Model List-Price Our-Price
2 37820-PZX-A09 CONTROL MODULE, ENGINE (REWRITABLE) 1 2006 S2000 622.77 467.08
2 37820-PZX-A11 CONTROL MODULE, ENGINE 1 2007 S2000 597.08 447.81

I need a pic of my car for my sig like the rest of you 07 GPW guys. by the way GPW FTW!!

 

PeeMP, I'm gonna head up to NorCal in the next two months. We could totally set up a shoot. I'll be rockin an 07 GPW on black/red too.

 

so the 07's are not reflashable, only the 06's?

 

I'm pretty sure the '07s are also reflashable, but the '06 hondata is not compatible.

Interesting thread...

I would think that an 06 ecu would plug & play on an MY07 car. Anyone know for sure?
