    calibrating LC-1 for 1st time - Blue guage blinking 7.4

    I think everything is wired 100%. I used alligator clips to connect to battery. According to the LED, everything calibrated perfectly. Once I hook up the guage...blinks 7.4 and nothing else.

    Please help.

    1) Make sure the ground wire for the gauge and the LC-1 are routed to two different ground sources!

    2) Remove the O2 sensor and test per troubleshooting guide.

    I actually had a wire crossed.

    I found that latest manuals online:

    DB gauge - http://www.innovatemotorsports.com/s.../DB_manual.pdf

    LC-1 - http://www.innovatemotorsports.com/s...Quickstart.pdf

    After I rewired - I am getting 21.8 after calibration.

    Does that sound right?

    I have not run the O2 in the j-pipe yet...so 21.8 is just what I am seeing after calibration.

    It should read about 20.0. Mine reads about 19.5-19.7 when calibrating. Try reseting it a few more times in open air

    Calibrate the sensor in open air should read 20.9.

    You are correct! 20.9 is the initial number after cal. When install O2 sensor in the J pipe it would drop to 18's-19's because the sensor now would be in a confiend space and oxigen levels are low/less. If you block all air entry you would see oxigen levels going down. I always warm up the engine before installing the O2 sensor and collecting AFR data. I hope this helps Jim with the LC-1 instrument.

    I have the ground for the gauge wired with a seperate alligator clip...but I clipped it to the negative battery terminal and everything worked great. If it did not work, I would have just clipped it to the engine mount.

    I think if this was a permanent install I would grab a ground block and solder everything in. However, I may use this thing 1-2 times a year.

    Thanks for your responses.

    Thanks again everyone. I will try opening the garage door for a few minutes and doing the calibration again to see if I get 20.9.

    The LM-1 & LM-2 should "free air" calibrate at 20.9 The LC-1 should "free air" calibrate at 20.0 The range for the LC-1 is 10.0-20.0 so you will not... should not see 20.9 (read the dynotune manual)
