i heard somewhere that if you have a chipped p28 in an obd-II car, it elimates the ckf (crankshaft fluctuation sensor). is this true?

 

Probably.

You would need the 150 dollar conversion harness and the 150 dollar chipped ECU....plus the ECU to chip....another 150.

450 to do this or.

100 to have a local shop replace the sensor.

 

A rechipped P28 doesn't look for knock and crank angle sensor I believe.

 

from my experience i had a p28 ecu chiped and tuned by ericks racing and it was in my 97dx w/ b16a. it eliminated the knock sensor and the secondary O2 sensor.
i had to buy a skunk2 obd1-obd2 harness for 150 though.peace

 

It should have never had a secondary O2 sensors, those were incorporated on OBDII cars. I just know my old Skunk2 chipped P28 had no knock sensor and ran rich as hell.

 

yeah my car is obdII.
