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 |

I've done the DIY-WB thing as well. I ended up tuning and then running open loop. There are several problems with the diy board that make it quite tricky to get running in a dependable way - namely the heater circuit is reliant on several resitances, and as such is not usually capable of heating the sensor properly in a 914 (mine has taken as long as 5 minutes to get to temp).
It's not for the feint of heart, but will give you enough information to get your MAP close to right. I was very happy with my MSed 1.7 before I gave up for a bigger engine. It is worth going wideband though - the days of tweaking carbs or FI based on exhaust smell and color, sound, and jedi mastery are gone. It's much much nuber to have hard numbers to back up your adjustments. |
