just finished installing jkobd.com ecu adapter, dist adapter and ecu using a jdm unchipped p28 replaceing my obd0 chipped pr3
i wired the vtec oil presure sensor and vtec wire but left the 4 wire o2 and the knock sensor un-wire being as though i am going to tune them out very soon using Neptune at titan motorsports in orlando
start up went great experienced a somewhat high idle but my idle was slightly high before with my engine set up ... let the engine warm up and then free revved to check vtec engagement and it his a fuel cut like rev limiter at about 4500 or so rpms ... anyone have any input? think it is because of the cel for no o2 and knock sensor?

 

p28 doesnt use a knock sensor, but you should have the o2 sensor hooked up.

you have to remember that now you're running the engine on SOHC fuel & timing maps. if i were you, i'd reinstall the PR3, if anything atleast until you get the p28 modified and tuned

 

so would that cause the rev limiter?
