It doesn't work if you the use Acurite adjusted, the absolute or even a correction to absolute. It can't even stay stable enough for the correction to absolute to stay consistent.
The key test for the bridge would be using absolute with a correction. If that isn't tracking well with other barometers, then there is definitely something wrong with the bridge barometer.
Also, look closely when you select the setting on MBW. The radio buttons can be a bit misleading due to their arrangement. Make sure you've got the radio button selected in the right column so that the correction is actually applied.
Yes, sound advice, it's definitely the bridge. I turned the Aculink display for b/p back on last night, here's my current Acurite Pressure dashboard reading

If I use the Absolute Pressure with 0 correction, same crazy range only it will be like 20/53 or something equally ridiculous.
