    Last Update: Mission Accomplished

    The 20 Ohm resistor I ordered arrived in the mail. All hooked up across Pos C/D, DTC codes have been re-enabled and no codes are thrown. The resistor does get a little warm though so be careful where you mount it. Link to ebay resistor I ordered in case you are interested:

    Also I did purchase the DM-5 gauge with the SM-AFR and recommend it for a permanent install. The gauge is as easy to hook up as the rest of the system.

    Note: You should also review your tune for B4105 O2 Switch voltage for whatever bank you install the WB on. In my stock tune the switch was at 450 mv, The SM-AFR sensor switches at 500 mv. Once changed it did get rid of some of the lean ~.2 and idled smoother.

    Hmmm... 10W resistor, and it gets hot... :-|

    MIL spec too.
