Well I been running this set-up of XD-16 & LC-1 with Xede for more than a year now, but recently I been getting E 9 error on my XD-16 gauge which mean low voltage error. All my connections are soldared. So what can be causing this error?(battery, altenator, etc) Also can this error effect my AFR readings to my Xede?

 

Did you try the innovate forums?

 

Interesting I didn't know they had forums, lol. But I spoke to them on the phone and basically they told me to check my connections and anything related to voltage.
