Innovate unless they have changed very recently were having awful issues.
Out of 4 used by a friend 4 failed, on 4 different cars, all replaced with another make all perfect.
Do you need one ?, big and hard question to answer, do you know what is "safe", unless you do imo it's pointless, if you do are you going to notice anything wrong before any damage results ?
Is it going to be a constant distraction, or worry.
I have a tech edge controller on mine, but I don't and never will use closed loop, even though for me afr is only a matter of putting the gauge in the car, all wire is there, and I have the gauge, but didn't want another distraction.
