F20c vtec oil pressure sensor issue

hey guys so i have a '85 rx7 with a f20c from a '00 s2000.
my vtec solinoid and oil pressure switch is pulsating on/off when im in vtec (above 5k rpm's). i took this as a bad oil pressure switch, so i replaced the entire solinoid and it came with with a new oil pressure switch
it still pulsates, but now faster, if that makes sense. i can just unplug it and hit vtec just fine... aha
for a piece of mind i installed a sandwich plate between the oil filter and engine, and installed a aem oil pressure gauge. oil pressure is just fine. any idea why the ecu is reading the oil pressure switch pulsating on/off ?

side note, THANK YOU FOR THE TRIP ON THE IC7 !!!
