IIRC, The MoTeC "wideband" lambda sensor is actually a Bosch LSM-11 sensor, which is not a true wideband sensor. I believe the LSM-11 is a high quality regular style lambda sensor for which Bosch provide temperature compensation tables. The LSM-11 does not contain an ion pump.
?

and please note, that only a Motec M800 (and probably PECTEL and some other units) will read a true wide band lambda sensor ..... it is also important to read the note about operating temps on 4 wire lambda sensors:
Carlos H.
Normally the heater must be connected to mantain correct operating temperature.
In extreme cases where the exhaust temperature will exceed 800ºC for a significant amount of time the heater element should NOT be connected

So if i understand correct when I want to monitor my A/F ratios accurately at full throttle with a permanent fixture then I need a 5 wire lambda sensor with a M800 ECU or Pectel T6 to read it?
Since I probably will be quite happy with my Ecutek flashed ECU when I get it back from Pete!!! Seems a bit excessive to have to buy another ECU to monitor A/F ratios:-(((
Can the standard 4 wire unit give me a reasonable indication?

Yes ..... like it says on the note, it just depends on the location, I guess that if you fit it after the turbo it would be ok, but as close as possible to the turbo like on the previous WRX's
