hey. i have on 03 and trying to get flashpro. can i get it for my stock ecu or do i have to get an ap2 ecu. how does that work?

 

Flashpro doesn't work with 2003 (as you surely saw already at Hondata web site).
regarding making ap2 ecu work on ap1 - i have no clue.

 

you need DBW for flashpro so only 06+ s2ks can use it....im guessing you could make it work with an 03 if you did a DWB 2.2 engine and ap2 ecu swap

 

You would have to replace a TON of components to make it compatible with a non-DBW S2000. The emission controls are different, the whole fuel system is different, ABS system, VSA, everything would need to be transplanted as a whole system into your '03. If you really want a FlashPro, you just need to buy an '06+.

 

Or just stick with an 03 and get the right tuning module-Kpro
