^I'm glad someone has my back. Trust me there is a a way to reprogram the ecu for every single s2000. Mugen and J's racing have found a way somehow to do it. The older ones might not be flashable through the odbII port but there has to be someway to reprogram them or they might require a daughterboard to be put in place. I know a lot of older cars work that way as my friend does a lot of tuning for them.
Now I think the 00-05 ECU can be modded but it wont be via a AP or a FlashPro.
There is a small daughter board in the ECU that contains a small EEPROM. That, I believe, holds the key to tuning the 00-05 ECU.
I have taken it off my extra ECU but I am having a hard time dumping the contents.

All the JDM Aftermarket ECUs are most likely made by Honda. I had a Mugen N1 in my hand and compared it to an extra AP1 and they are the same.

What I have heard is that the program is stored in the processor itself and not in an separate EEPROM. That's why all JDM Tuners send their ECU's to HONDA to get an extra Daughterboard with the EEPROM activated. My guess is that HONDA only has the codes for reprogramming these older ECU's.
That's the reason why Hondata is using another ECU (RSX) for the K-Pro in the 99-05 S2000.

Add me to the list as well! Im just wondering if this thing comes to production will I be able to utilise it with my intake-header-exhaust-HFC combo? will it be able to fine tune everything? if not then what will be my next option? Reflash or standalone?

It this comes out I'll eat my hat, i dont think it will. 10years now.
Cobb will need to break/crack the algorithm first, it will likely require opening up the ECU and soldering on a socket or piggy backing onto the original chip.
If they do hats off to them but i cant see it.
Mugen/J's did it sure but they were given the go ahead by honda and the codes.
