Default Chipped P28 H22a... no knock sensor?

dropping a h22a in my 4th gen (95). have a chipped p28 with a h22a basemap. friend told me that the p28 doesn't have the circuit for knock sensor so i don't have to wire that up.. is that true?

i dont think u really need it. after i got mine, the hesistation i had with my p13 was gone. and apparently the hesistation in low rpms was due to the knock sensor.

I've just wondered, since on a P28 a Knock Sensor isn't used, so does the Knock Sensor still have to be "in" the block..?? Or can you just leave it out..?

You can remove the knock sensor - it will not cause any problems - besides if it still working you can sell it
