Wideband O2 sensor and piggyback controller
Has anyone installed and used a wideband O2 sensor/gauge and a piggyback controller like the Apexi AFC Neo? I just finished installing the 987 airbox, 74mm throttle body and the 997 plenum and am thinking that using the Apexi to tune the afr may be a more precise approach vs using an off the shelf modified tune (Softronics or maybe the 996 tune). It would also be less expensive. I would be interested in anyone else's experience installing these pieces and using this approach. I'm also wondering if this is going to modify the afr during open loop or would it only help closed loop? Any downside?
