I have a JDM OBD1 P13 ECU laying about gathering dust, i was wondering, seeing as H22a preludes also have dual runners in the inlet manifold, will this ECU work in a OBD1 GSR? I know the P13 activates vtec and the secondary butterflies at the same RPM (5k i think) Would there be any benifit in running this ECU and has anyone else tried it before?
