ELD from ECU outputting 4.53V? - Resolved

So I've been having a problem with my LC1 as some of you may know. So I completely cut all the wires and wired just the neccesities and found something very peculiar.

I verified that I have cut my ELD wire to put the WB signal to Pin D10 on my P28 ECU. Right now there is NOTHING connected to the ELD but the stock cut wire, and my Voltmeter is reading +4.53V. I think this is why I'm having so many problems, if this wire is cut, shouldn't it be reading O Volts???

I THINK I FOUND THE ANSWER... I traced all my wires and found out that my ELD was OUTPUTTING 4.53V. What the crap??? Then I looked at Hondata's help file and found this little ditty...

I contacted Phearable.net and they confirmed that they didn't remove whatever this is and that was probably causing my problem.

I have since changed my Wideband input from Pin D10 ELD, to my Analog Input 1 on Pin D12. Now everything matches up fine and NO MORE VOLTAGE OFFSET!!!! YAY!!!
