neither of those are widebands.... those 2 are Air/Fuel piggybacks. They adjust the air signal going to the ECU allowing u to make changes to a fuelk map. So, They are not widebands, 2 whole different things.

And both have ZERO control of ignition timing...something you're going to have to likely back down once you increase flow with racing type headwork.
