ok i got a 95 gsr in a 93 cx hatch.v-tec soleniod is hooked up straight to the ecu BUT IT DONT WORK!!!check engine light flashes KNOCK SENSOR and O2 SENOR!!!i checked oil and it is good!!!wat SHOULD I CHECK OR DO???


AND SECOND PROBLEM I GOT IS WHEN I FULL THROTTLE AND IT HITS ABOUT 6000RPM IT STARTS SPUTTERING BUT RPM STILL CLIMBS...IT JUST SOUNDS LIKE ITS STRUGGLING TO HIT RED LINE....


PLEASE HELP ITS IRRITATING ME ALOT...THANX HONDA TECH PEEPS

 

IF your ecu is stock vtec will engage at 4400rpm. perhaps its your secondary butterfly's are causing trouble. If you did not wire them they will default to open anyways.
try changing fuel filter.

 

my ecu is chipped but the didnt take out the knock sensor...v-tec suppose to hit at 4400 and red lines at 9500...

 

If the cel is flashing for the knock sensor, vtec won't engage and the engine will run in limp mode. Is the knock sensor even wired to the ecu? What ecu are you running?

 

runnin a gsr computer...

 

did you wire the knock sensor?

 

ok i changed the soleniod,knock sensor is isnt flashin and now im really stuck !!!!HELP

 

cel isnt flashin knock sensor but flashes o2 sensor and vtec doesnt work....NEED MAJOR HELP GUYS,PLEASE!!!!!!!!!!!

 

An obd1 gsr p72 ecu should still engage vtec even though the knock sensor is not present. The o2 sensor problem your having is more than likely the heated element circuit part of the sensor. But that still would not prevent vtec engaging. Im saying all this based on obd1 p72. you say it starts spluttering at 6000rpm. are you sure your chip is burned with a 4400rpm vtec point. It could be running very lean at vtec point (6000rpm??)
Are you sure the solenoid is getting 12v?
Sufficent oil pressure? (57psi i think)
