alright here's my problem. i am running a p28 ecu with the mugen program. i recently installed a v-afc. after installing it at in 3rd and 4th gear around 6000rpm i throw the map sensor code. my v-afc is wired correctly. has anyone ran into this problem before? also, is anyone running the same ecu/program/v-afc? i've heard a capacitor is needed in the ecu, but not too sure. any help?
