The reason that I went with an Innovate the second time, rather than buying another AEM (which has been a good product) was the ability to calibrate and the corresponding accuracy.

The Innovate gives the opportunity to calibrate the wideband frequently in free air to compensate for the long-term degradation in the actual wideband sensor.

The AEM wideband (which can't be re-calibrated) can be off by up to 0.5 AFR after years of use, which could mean death to a closely-tuned turbo car. I think this is the reason that many people do not like them.

At the same time, on an NA car the AEM is fine because if you shoot for 13.2:1 by the wideband, you are probably reasonably close to peak power (error range of 12.7:1 to 13.7:1, which all makes good power). Running a NA engine lean of 13.4:1 (peak power) won't hurt it, you will just lose power (no valves to burn or pistons to melt).
