    Tuning with stock exhaust

    I have a car to tune with stock exhaust. There is no room to put a WB in front of the CAT. I'll tune idle, and part throttle with the STFTs but what about WOT?

    I don't think the WB would be accurate after the CATs.
    Thanks,
    Sarge

    Take out stock o2 and put it there. You have it in open loop ignoring them any way.

    The front 02 is up high on the exhaust manifold. Not a good spot with the heat. The rear 02 is after a CAT.

    Anyone know if that kind of heat is an issue for an NGK/NTK sensor?
