F.I guys with wideband Don't forget to calibrate your wideband often. It says to do so in the instructions of my LM-1...especially if running a rich turbo setup. I hadn't recalibrated mine since it's initial install and it was off which explains some tuning confusion I had.

Must be specific to the newer widebands using the bosch sensor. The old ntk sensors don't vary much at all. But calibrating any controller or sensor would not be a bad idea.

But it is important to do.

unit's that use the built in trim resistor in the sensor connector don't require recalibration. I beleive the LM-1 does some heater calibrations and nerst cell testing to get a better temperature comp for the sensor output.
my AEM units don't, my Techedge (NTK) require a manual tweak when you swap sensors only, my LM-1 has the cal button Yes, I've got 4 WB's( one is dual channel)

The newest tech edge (LSU) has a calibration you run from a PC, it does change quite a bit after a while. I recalibrated mine when I sold the car and it was pretty far off as far as the numbers in the calibration utility went - dont know how much off it was as far as a/f though.
The older tech edge I had (L1H1) never changed after months of use, it just had a trim pot to calibrate it.
