The topic of WBO2 sensor and controller comes up again. I have done a search on the forum, but have not found complete information.
Which controller is the best option for the LSU O2 sensor? GoTech manufactures a unit for $350.00 Tech Edge has a DIY kit for the controller for $145.00 USD. MegaSquirt speaks of a stand alone O2 wide band unit but I cannot find a finished reference or site for purchase. AfreshBoardBOM http://www.squirrelpf.com/msavr/index.php?...=AfreshBoardBOM speaks of a unit, but seems to be still in design phase. A preferable option would be a unit that could interface with MegaSquirt and/or Kit Carlson unit. Dave Hunt, do you use a WBO2 closed loop feedback to your MegaSquirt? Is the SuperMegaSquirt design include an O2 sensor input? I'm at that point in the design and can't seem to find a reliable experience source. Thanks, L. McC |

UltraMegaSquirt (not Super) will have WBO2 driver circuitry on-board, but it's still a ways off.
IMHO, the DIY angle of WBO2 is still too new to rely on. I'm not entirely convinced it's a good idea for the T4, either. O2 sensors, esp. the WB units, are easily contaminated by oil in the exhaust, and T4s are a bit oily. I'd use one of the hand-held meters (Innovate, or the complete Tech Edge thing, which is more than $150 with the display) to set up an open loop MegaSquirt, then remove the sensor and use one of the screw in plugs to seal the hole. You can reuse the sensor later to double check things at tuneup time, but run open-loop most of the time. |
