Premium Member blackout Posted January 6, 2017 Premium Member Share Posted January 6, 2017 Might be a dumb question, but... I'm in the middle of welding a custom exhaust and will be sending my ECU to you for a flashing, and I was wondering whether the O2 sensor is still needed after the flashing? The reason I ask is if it is not needed, there is no sense welding a bung to the new exhaust. Thanks! Craig Mapstone Upstate New York Link to comment Share on other sites More sharing options...
2wheeldynoworks Posted January 6, 2017 Share Posted January 6, 2017 Yes, you will want to weld on an O2 bung and keep the O2 sensor installed. Side note: even if it wasn't necessary, it's a good idea, as it can be used for diagnostics and dyno tuning, or if we have to put you back to a stock ecu setting for some reason, the ecu won't be happy without it plugged in either!
