ohhh man!!! hondata is almost there with there ecu for the '06 civic si!!!
take a look at this:
"Fueling has not been cracked to date, but Hondata can now control everything else - cam timing, ignition timing, rev limiters, VTEC, etc."
"Hondata managed to increase hp from 224 hub hp on our Dynapack 4000 to 231 hub hp just using a rough cam timing map and adding some ignition timing. Fuel was not altered, because at this point, it can't be."
