I don't think ignoring hit error bar is a very good idea because it DOES work as it should and it's for you to diagnose(not sure how to spell) between your click timings and the actual song, rather than the beatmap itself, because it's the beatmap that's mostly not right.

Instead focus on what the hitsounds relate to in the music and time it in sync with them. Also fixing your UO takes priority over messing with LO. The only time you really need to mess with the LO is when the map is clearly and painfully out of sync; the couple ms inaccuracy are acceptable because windows itself fluctuates plus I don't think anyone can hit a stable -1/+1 every time they play. If you're seeing that on EVERY map you're playing that you hit early or late then it's commonly 2 things: 1) your UNIVERSAL offset is wrong 2) you're not listening to the music.
To fix your universal offset simply go download the offset wizard song by peppy and put these sounds into your skin [ http://puu.sh/9BkRs.zip ] Then go into the options and open up the offset wizard (Have the offset wizard song by peppy playing). Stop the music and raise the offset to +10 or +20 and then start it; every tick try and lower it by 1ms until the sound shifts to a deeper almost muted kind of sound. From there go further about 3ms and you should be fine. If you're uncertain about it you should be able to hit stop and then play, the metronome ticks should sound the same as before you stopped the music. I use -5ms on my laptop, -3ms on my desktop. Commonly I see computers be within this range.
And I'm not sure why but universal offset never really worked for me, I still get same delay even if I put -15ms comparing to put -15ms manually.
