p28

[typesiracing]

i'm doing an ls/vtec setup in a 93dx.....i know i have to wire the two wires for vtec........but i'm not sure if i have to do anymore.....because i have a b16 head (no purge control or secondary butterfly) and i'm using a chipped p28 so there is no knock sensor.... i've read a lot of articles but all of them talk about a p72 ecu....so i'm not sure what the p28 looks for..
thanks

vtec, vtec pressure. You're done after those two. You can disable vtec pressure too, but that depends on what chip goes in the ECU.
