What you need to run Hondata is to get a TSX ecu, calibrate it to run with your car immoboliser and key. Then send the ecu, your immoboliser and key to hondata for reflash to run k-pro.
This is what happens last time i checked. I am looking for engine management for my car as well, but i am probably going to see if i can run something else in replacement of k-pro.

I already have an auto tsx ecu and rsx-s ecu. If i decide to not go the k-pro route, if anyones interested, let me know! =)
