Interesting. The 993 doesn't have a check valve there, so it must be back in the engine bay. I guess this trick wouldn't have worked for me anyway.
Yup.

Perfect.

Great! Thanks guys! I ordered the parts.

Now on to my next quest of finding a wideband O2 sensor... As I understand it the current sensor can't give correct AFR readings other than the cruising-down-the-street type.

True.

The Innovate Motorsports sensor is well respected. I like my LC-1 a lot. I don't use the gauge, I just monitor the data on my data logger's dash display.

You'll also need to weld in a new bung for your o2 sensor, or else figure out how to rig your setup to use the narrowband data from your wideband. It can be done apparently.

Thanks Eric. I've looked a the LC-1, but would rather use a more simple (and cheaper) solution. I'm researching how to "rig" a wideband O2 sensor now. Any help would be greatly appreciated

Geoffrey

You can install it one of three ways.

1) remove the narrow band sensor and replace with the wide band sensor (not recommended)

2) Use a wide band sensor with an output that can output a narrow band signal. You replace your current narrow band sensor with a wide band sensor and splice the factory wire harness to the wide band controller output. (works nice)

3) Install a second O2 sensor boss and run the wideband separately. (this is how I have my car wired). If you need someone to weld the O2 boss in, stop by, I'll do it for you. I like this option the best since it preserves the factory setup.

Thanks for the offer Geoffrey! I'd love to take you up on it! Maybe in the spring?
