Okay so ive been trying to figure this out but i havent had any luck. I loaded a base map for K20a2 jrsc 440cc 5 psi.. however i have a k20A with a jrsc 440cc 5psi currently.. I had 2 problems but i delt with one already *low fuel pressure voltage* however i still have a "code 22-4" "DTC P1259" "Description: VTEC System Malfuntion (oil pressure switch)" then "Daughter B ored Communication error". If some one could shed a little light on how to get rid of this, that would be great! THanks

For the JDM K20 you need to disable the VTEC oil pressure switch (found under VTEC in the parameters window). The daughterboard error usually indicates that the engine ground is not good or that the kpro board inside the ECU is loose. Pull the top off the ECU and check that the board inside is not loose in any way. If you do remove the screw holding the kpro in, use locktite when you re-install the screw and do not over-tighten the screw as this will distort the kpro board.

That cleared it all up! Thanks Hondata!
