Dual wideband- Pre or Post turbo?
Vette' project I am working on. Twin turbo. Nice 321 stainless headers. Very nice 321 merge collectors. About a foot of 3" after the collectors and to the turbines. Left and right banks never meet each other.
Dual wideband seems sensible. Should the O2 sensors be installed before or after the turbochargers?
If after, how close or far from the turbo's should they be located? I guess same question if pre-turbo.
Who offers the best all around dual wideband controller with both options and and reasonable cost? Best bang for the buck. Money is always an object.
Is a dual system totally unnecessary?
Thanks, RonO

We always put the WB's after the turbo, and try for a 12" distance. This minimizes the egt and pressure influence on the sensor.
They need to be above horizontal, to prevent the pump cell from getting cold start moisture contamination.
What controller are using for engine mgmt?
FAST has a dual WB system.

I do have another question. The dual WB systems I have seen always have a stand alone controller, either a gauge or handheld unit. Do they somehow inteface with tuning software? Do they need to?
