Hello,
I was wondering if anybody knew if the MX5-NC Pre-cat sensor is wideband or narrowband stock. I’m assuming it is narrowband but would like to check as I’m struggling to find any specs on it. I have a Plug and Play ECU and wish to tune the engine and as such need a WB02 sensor. If stock is Narrowband would anybody know where to buy an aftermarket WB02 that is compatible? Car is decat so only have access to upstream fitting. Any help appreciated
