b93hatch18

got a 93 hatch with a b18 running staight exahust no cat throwing an o2 code obviously and im throwing a wheel speed sensor code im guessing because the integra used it for abs chipping my computer should get rid of this prolem right? also im wondering if me not running the o2 sensor will cause it to run a little rough idle just when its cold when it warm its fine just a little stutter and poping no misfire and i still get proper gas mileage and could getting the right chip cure this?

what ecu are you using? is it OBD1 or OBD2. running no O2 at all will cause the car to run rich, a loss of power, and poor fuel mileage to say the least. if your running a primary O2 and not a secondary O2 (assuming your using an OBD2 ecu which i dont think you are) you will be fine. you need a primary O2. the secondary it to check the condition if the cat which you dont have and doesnt serve any other purpose. and chipping the ECU isnt going to fix either of your problems.

its running obd1 and the kid i bought it from a good freind of mine said he tryed putting a primary in and it threw the code still its supposed to be a 99 motor that they ran the obd1 computer on it he bought the swap off someone else and put it in it smells a little rich but i still get good fuel mileage around 30 or so
