What is a wideband Turbo?

A wideband oxygen sensor (commonly referred to as a wideband O2 sensor) is a sensor that measures the ratio of oxygen to fuel vapor in the exhaust exiting an engine. A wideband oxygen sensor allows the air/fuel ratio to be measured over a very broad range (often from around 5:1 up to around 22:1).

Do I need a wideband for tuning?

OPTION 2: Getting it Pro-Tuned If you plan to head to the rollers to get it setup, and want a more hands-off install, then no need for a wideband at all. The dyno operator will use their own wideband during mapping, will optimise the fuelling and ignition, and, everything being equal, it should never change once tuned.

How long after turbo install wideband?

Re: how far downstream does a wideband need be? ( Motec recommends within 0.5 meters (so ~20 inches) of the collector on an NA motor, and the same but from the turbo on an FI setup. On our SFWD cars running integrated EMS widebands, they’re usually no farther than 6 inches from the turbo.

Where is a good place for a sensor on a single and twin turbo set up?

O2 sensor placement on turbo application. ALMOST Spidey ! O2 sensor placement on turbo application. Where is a good place for a sensor on a single and/or twin turbo set up?

Can a WBo2 sensor be used for high pressure?

WBO2 sensors can’t be used in a (pre-turbo) high pressure/high temperature location due to false readings. Dual WBO2 sensors can be used on naturally aspirated, twin turbo, supercharger & nitrous oxide applications.

Can a wideband O2 sensor be overheated?

Wideband O2 sensors can be overheated. The best method is to temporarily run the engine with the WBO2 sensor in each header collector (or slightly farther downstream), note the air/fuel ratios, then permanently install it in the leanest bank for the safest possible scenario.

Is it OK to put O2 sensor before turbo?

Escaped on a technicality. Eh, don’t (permanently) put the O2 sensor before the turbo. None of them will live at those kind of EGTs for long.
