Anybody install a wideband O

Where did you mount the lambda sensor?? just after the extractors/collectors come together is a good place. I've also got the innovate wideband, but the portable handheld, not the dash mount one, and I've had it in many carb fed cars, plus my own turbo drag car. The signal tends to bounce around if you have an airleak in your exhaust ahead of the sensor or if your sensor is not at optimum temp. (is your heater wired in and working?) If you mount in the tailpipe end, it also bounces around at low rpm due to reversion back into the exhaust between pulses of gas

I also have the hand held unit but the programing should be the same. Try going into LM Programer. There should be a sensitivity adjustment for the 0-5volt and 0-2volt output. Your guage should be using the 0-5volt. Turn it down to to the minimum update rate. You dont want it updating to fast unless you are loging. Also sounds like you may be
overheating the sensor (high EGTs). Its very important to have the sensor way down stream or you will overheat it and the readings will be all over the place. And what bones said is right. If you have any leaks in your exhaust the extra oxygen will throw the reading off as full lean.

Ok thanks guys,
I recorded a log while the car sat in the driveway. All verical lines on the log, like an on/off switch.
I then went into the LM programmer and adjusted the update rate to 1/6 sec.
Now I don't think the update rate was really my problem but changing it made the LC-1 recalibrate itself. It recalibrated the O
