Is it worth fitting a wideband ?
 

Hi all hope lockdown isn't driving you mad.
i have been thinking of putting a wideband in my car now for while but can't make up my mind.
Is it worth it. I already have oil temp, pressure and boost. Is a wide band a good addition ?

If it has an audible warning function it would be useful.

I wouldn't have a performance car without one now, saved me a potential engine failure a few years ago.
