Does the Boxster come with a wideband or narrow band O2??

Hey Gary,
O2 sensor; If it does, It’s not one I could use (I really don’t think it is). Stock is 4 wires +,-, signal & grnd. The widebands I know about are 5 or 6 leads.
The Bosch LSU type my controller/ gauge requires has 5 leads to a plug, the controller has 6 ( one terminates at the plug into an internal resistor or somthing). They can be pricey but, not bad at Amazon for $65.
The difference (If you don’t know) is a stock narrow band basically trips at some “above or below” voltage point. Wideband doesn’t trip, It just translates 0-5v into 0 to 20 (or something) AFR units.
My controller remaps and outputs a narrowband signal to emulate original feedback, just like the original narrow band, to feed into the ECU. Saves welding a separate bung.
Hope that word missive helps.
Regards, PK
