. . . to run my DIYPNP and LC-1 while still naturally aspirated?

Do I unscrew the pre-cat O2 sensor and leave it electrically connected and just tolerate a check engine light? Then wrap the sensor in a few ziplock bags, tape, and tie it out of the way? Not sure how hot these things get so not sure if that's a good idea.

 

I would unscrew the pre-cat 02 and screw in the LC-1 in its spot. Then I would hook the narrow band output of the LC-1 up to the stock O2 sensor wire. This should get rid of your CEL and allow your MS to get the wideband signal.

 

well. he has a DIYPNP, there's no stock ecu left in the equation to either 1. send the NB signal back to or 2. throw a cel.



I'd, depending where I mount the LC-1 and build the unit, would either connect the output back through the stock NB connector or bring it into the DB15.

 

If he is running a DIYPNP then why is the CEL even coming on? Isn't it controlled by the stock ecu?

 

I don't think he's done it yet
