Chewed up my O2 sensor, can I do without it?
Well, I screwed up my front O2 sensor when trying to install my new motor. I should have not put it in until after I installed the motor. It is in the stock location just below the uppipe.
Anyway, when I was putting the engine in it rubbed against the frame and cut some wires where they go into the sensor, so no way can I splice and fix it.
I have several questions, here are my mods.
Stock 2003 WRX motor, DNPerformance catback exhaust, DNP uppipe with 2 bungs (1 for O2 sensor 1 for stock EGT), UTEC, Walbro fuel pump and WORX BOV.
#1) Do I need this O2 sensor for the engine to run well if I am using the UTEC ?
#2) I know it will throw a CEL without it, will an O2 Simulator fix that?
#3) In the spare bung on the DNP uppipe can I install an EGT for my use?

1) You have to have the o2 sensor for your car to make correct judgments on air fuel ratios.
2) Possibly don't know why you would want to try after response to question 1

1) You absolutely need the front O2.
2) Buy a new O2.
3) Uppipe EGT sensor aren't very good since the exhaust flow cools alot before the uppipe.
