    I've read that Wideband A/F sensors get killed in a high pressure area like between the engine & turbo, but will it live for any time in a low boost set up like 4/5psi?, its on a bike & I only have a short out let pipe from the turbo. Whilst asking, If that's a no, then how long does the pipe need to be from the sensor to the end, so as to prevent reversion from screwing up the sensor readings? Thanks

    Maybe if you have a large heat sink. I had an LC1 mounted pre turbo, and an AEM UEGO post turbo on my remote setup and they read the same AFR reading. The only issue is that i killed about 3 or 4 sensors for the LC1. The LC1 would throw an over heat code just about every pull.

    Ok, thanks for that, I should have said the turbo is mounted at the rear of the bike, and I do have a narrow band sensor mounted on the pipe around the foot rest / swing arm pivot area, perhaps it could be placed there & live for some time?
