LC-1 with DC gauge. Good quality, easy install, and customer service was excellent.
Yep, I have the same. I also tied it in to my Traqmate so I can graph the A/F ratio through out the entire race. That way I can see how flat the curve is and make adjustments accordingly.

^+1. Nice to to overlay all the data. Even though I have a lot of sensors, I really only look at speed and A/F data these days.

I welded a bung into the downpipe. Make sure you can get to the sensor because you will need to remove it from the bung and place it in clean air for calibration.

I have used the AEM unit on a different type of car for a couple of years now. I have had no issues with it and it is always within a tenth or two of what the dyno says. No calibration, just plug and play.

Or get a 1.8 downpipe. Yes it is legal.

Me too. It had a serial port for datalogging though I never did hook it up to my DL-1 so I can't speak to how well it worked. I can say that it was very easy to read at a glance and reliable and was within about .1 of a tailpipe lambda used by my dyno operator. The probe had zero problems for two seasons and was still accurate when I sold the car.
We ordered a new downpipe from Mazda and I believe the OBDI pipe is superceded now? Because it had two bungs.

Great info. I'm looking to order the Aem as above. 1. Is their an extra bung on the 99 or do I need to weld one in? 2 Can this be later connected to a Traqmate and how is it done? Don't have the traqmate yet.

forgive me for not really understanding. The 1999 I am building has one bung in the downpipe which will be used for the stock O2 sensor. I will need to have another bung welded into the downpipe??? Do I just removed the shielding thats on the pipe around where it will be welded??? Does it matter how far down the pipe it goes ??? or how far from the other O2 sensor
What my guy did for me was take a torch and cut a round hole in the shielding a tad larger than the weld bung. He then blew out a hole in the pipe large enough for the bung. Once welded in I can use it for a gauge or when dynoing the car. Mine is a few inches beyond the OEM point.
Maybe someone has good information on your other questions...Does it matter how far down the pipe it goes ??? or how far from the other O2 sensor?

You want the sensor as close to the manifold as possible. Mine is just below the OEM bung. The new bung must be welded carefully. Even the slightest pinhole allowing air into the area will really mess up the reading. That is why I don't care for the clamp on mounts.

Lee, did you use a straight or angled bung. I can only find a angled weld in type at the mythical flying horse auto parts. Any suggestions where to get a straight bung if needed?

It's what you get when you order new from Mazda.

Like gatoratty said, the LC-1 should come with a straight bung.
