ok i've been seaching for awhile on my new ls/vtec swap im trying out....ok heres what i got...... 97 integra ls with a b18b and stock ecu (obd2) and just recently a 97 gsr head and dizzy (obd2)...ok can i use the stock ls ecu and if so how do i wire it up so everything works properly if not what ecu should i use..... and i still also need a wire diagram thanks guyz

 

you need to run a vtec ecu like p72 or p73 obd2 I have p73 for sale you need to run wires for vtec , oil pres, knock ,I thing dizzy is same either way. just find a ecu pinout for gsr obd2 ecu and run the 3 wire and you should be good to go.

 

run the type r ecu for lsvtec on obd2. it performs better then the gsr obd2 ecu. then all u have to do if add the vtec wires and sensors to teh pinout on the ecu harness.
