I do know some systems need to be calibrated every so often. Which units require calibration? I have the WMS, it's $400, but no calibration needed and it also has data logging. http://sdsefi.com/wmsmm.htm

Mark,

I certainly have very little direct experience (1 day of dyno time with a wide band total)

but my understanding on the calibration was that it was to compensate for what amounts to "wear" on the sensor. build up caused by contaminants.

the propaganda from innovate claims that race fuel, use, leaded fuel, etc. cause a build up on the sensor and that the calibration can help the system adjust for this contaminant.
