You fast guys that run race fuel at the track for high boost, how often do the O2s take a **** with C16?

 

So far, the NTK wideband (UEGO) seems to be less susceptible to lead poisoning than the narrowband sensors, and I've heard of similar results with the Bosch UEGO. Even the NTK rep told me I could do short runs (like some 1/4-1/2 mile racing) of leaded gas without permanently fouling the sensor. I know with my old 3-wire setup, I needed a new O2 sensor after even 1 tank of leaded gas. If I didn't change it, I started getting unpredictable readings and weird surges and misses when driving.

In my opinion, widebands are more lead tolerant. Regular O2 sensors need to stick to unleaded, unless you plan for regular sensor changes.

I've gone thru one already, a Bosch one. That's why my last past was aborted, I went 9.96@134 coasting.

 

Where can you get the NTK widebands?

 

I hope you go to MIR next week and beat that Stenod car.

I bought from them and it worked out well.
