I have been fighting with trying to tune for a while now but keep coming up short. The problem is the wide band signal to the efilive. It is an lc-1 analog out to the efilive. the afr reading seams to switch up and down from 13 to 20. I checked the voltage coming out of the lc-1 and it seems to be smooth at 2.4 volts but the afr reading while logging the tune goes all over the place. If I hook up a battery to the efilive input it is a rock steady reading. but when the wide band is hooked up it reads lean to rich constantly. even with the wiring unplugged from the efilive there is 1.35 volts coming out of the input with no signal from the wide band. the afr reads 16 with the wide band unhooked. I tried an aem wide band before this lc-1 and it had lean spikes and read erratic also.Is my efilive unit bad or what do you thinK?
