Hondata

I have heared that somewere there is a software that measure HP according to hondata kmanager log files.. have any one heared about it ?

There are two things available - KDyno, which is standalone software; and RazDyno, which is a spreadsheet. I wasn't able to make RazDyno work, but that's likely because I'm running OpenOffice rather than M$.

RazDyno gives you "road torque" numbers, while KDyno gives you some arbitrary unit of acceleration. They also aren't comparable to real dyno sheets; a heavier/less aerodynamic car will put down lower numbers than a lighter one. Additionally, if you're driving up an incline for the datalog, you'll put down lower numbers.

It's a tuning tool for people who don't have access to a dyno - it's less accurate though.
