How long has your LC-1 sensor lasted?

[RomChip200]

I'm a bit surprised.

I run my two LC1 since 3 years now (maybe more), fixed installation (new bungs in the testpipes just before the high flow cats in the 9:30 clock position) and daily driving. No heater on them.
I would say >5 free air calibrations per year.
They always run fine (except some error codes when ignition is switched on sometimes, E2 E9 AFAIR but disappear on the next try)
Maybe running 100% E85 for a while makes the diff.
