ok, over the weekend i put a 92-95 civic ex/si motor (d16z6) into a 97 dx coupe (d16y7) i noticed that there was a sensor down by the crank on the 97 dx motor that looked like a crank sensor..

ok, now my question is:
do i have to have this with the d16z6??
i am using the 97 dx ecu with a RPM activated switch to control vtec..
i am also using the 97 dx intake manifold....
what is that sensor by the crank??

thanks
brian

 

no one?? i need to know about this, so the car will run, i havent tried starting it yet becaue of this..

will i throw a CEL??

get the correct ecu if possible out of a 92-95 ex or hatchback si - vtec does not just involve activating the solenoid........the ecu has a different and more aggressive set of fuel maps for the vtec lobes than the normal lower rpm lobes...... your vtec just wont be the same. - not to mention the ecu makes sure the conditions are right before activating vtec by making sure there is enough oil pressure in the head to run such an aggressive cam.

just my 2 cents.

(ps - im not sure on ur sensor, but i would say if u get the correct ecu - u could leave that plug on the harness unplugged since the ecu dosnt support that senor on that engine)

 

but the problem is the the kid is out of money and he cannot afford a jumper harness from obd2 to obd1... and i know about the fuel cuve gige but i have no other choice....
anyone alse ever use the dx ecu with an rpm swich to run vtec??

does any one know that webpage all about the d-series motors??.. maybe they can help me since know one else here can.....
brian

 

that sounds like the crank angle sensor

 

yeah but do i have to have it??
brian

 

using a obd2 ecu, yes. OBD1, no

 

for the fuel tell him to get a apex vafc or the field vafc you will then be good to go for fuel and vtec

 

just swap the whole oil pump assembly with the sensor and all...then just plug it in...if you dont connect that sensor..ECU will not be able to time motor right and you WILL get a CEL.
