Your brackets are in the wrong place for the EGR PID. Try this:
[PID.2811]/.5+10 No need for parentheses. I'm not sure where the .633 that Wicked is using came from but the equation goes like this:
volts / (voltage range/Device range) + (Minimum value of device range)=AFR
This breaks down as follows:
Volts= Incoming voltage reading, typically between 0-5 VDC.
Voltage Range= Range of sensor, typically 5
Device Range= Range of AFR that your instrument is set to read. For example if you setup your LC-1 to read 10-20 AFR, then the range would be 10, the AEM ready 10-20.
Min. device range= Lowest AFR reading of device. In the example above it is 10.
Using the numbers above, the formula would read as follows:
EGR volts/(5/10)+10
or
volts/(.5) +10
Therefore if you have a volt reading of 2.5 volts, this should translate into an AFR of 15.
(2.5/.5)+10=15. If your AEM gauge or LCx Logworks is displaying a different AFR then HPT play with the +10. I ended up using +9.8

Also, if your WB is hooked into the EGR input into the PCM then it should not be steady, something sounds like it is wired wrong. Disconnect the WB and make sure the EGR signal goes to 0.
