MTX-L wideband issue

[5timesturbo]

So, I finally finish my head job and doing last minute things before I take her out and my innovate mtcn-L wideband gauge is doing some where stuff. It is showing me triple 8 (888) and will not go through the calibration procedure. In fact the third eight is like blinking intermittently. I've unplugged the is sensor to see if I could it to go through the calibration procedure but it will not.....anyone ever have this issue before???
