[Supras] richness under boost

[Walker, Brian (Rich. Dist)]

Sean, this brings up some good info. I understand not wanting the sensor
in direct flame constantly as you mentioned but how will random flame
fronts effect the sensor? I would imagine most places in the DP are
going to see a flame fairly often. In fact this weekend at an event I
was told the car fired a large flame out of catback at one point. I also
recall last season when the old DP developed a hole (at the flex joint,
behind sensor location), flames were seen under the car many times.

Still seems to be reading well (same readings I always see, with no
input changes) Sensor has been in for ~2.5 years.

Just buy an Innovate LC-1 for 200 bucks and install it in stock O2
sensor location. Just having a wideband in the car helps out a LOT. My
old NA supra ran MUCH smoother just from that (used narrowband output
for ECU and wideband output for tuning). Whoever told you not to use
wideband O2 sensors for long periods of times must have been referring
to old obsolete non-heated sensors. Newer 5 wire wideband sensors are
heated and have no issues (unless you install it in an RX-7 where the
potential flamefront directly in the exhaust flow will melt it.)
