I have had it on the car for a little while and for a non FI M it reads 12.3-12.8 at Full Throttle. Many say that a non FI M should be at 13.7-13.9 so I was told that I need to calibrate it. HOW? the instructions say it has a little tab in the back that I need to turn, but what do I use to reference how much I turn Etc?

PLEASE HELP ME!!!!!!!!!!!!!!

thanks guys

The calibration you are referring to is for the analog output, not the gauge reading. Assuming you have a good sensor, the gauge will read accurately. Your car is running rich.

The sensor and gauge is new, So basically the only way to find out is get it dynoed ya? Ow another thing I put the sensor in without a 10 degree slant could that make a difference?

Without looking at the manual, and based on my experience with my Innovate LC-1 unit....

1) You may have to do a "free air" calibration so the sensor and the sensor controller have the proper reference point. This procedure is typically required with a new kit or when replacing a sensor. The best way to do this procedure is with the O2 sensor not installed in the exhaust piping (to ensure you are sampling pure air and no exhaust gasses). If done in the exhaust piping, wait until the car has cooled down completely (like when parked over night) and your exhaust piping should be clear.

2) Verify the output of the wideband controller is setup correctly. In the case of the LC-1, which has 2 analog outputs, one is setup for the wideband sensor that comes with the kit and the other output is setup to simulate a narrow band sensor. These come pre-configured from the factory on the LC-1 unit

3) There may be some other calibrations you need to do for the controller, such as a heater calibration, etc. But not all units are the same in this area.

Good luck.
