Looks like for the stand-alone EC3 auto tune it must have the Closed-loop option.

Does you EC2 have that?

I also have the EC2 & EM2 with the autotune. It does work, but it only makes changes to the map table at the address that you are currently on due to your throttle position. Moving your throttle position to other addresses will result in gaps where it is hard to hit each address using the auto tune. At this point though you should have a decent base line to work with and you can just manually go through the table to make adjustments as it will be obvious which ones need to be adjusted. Then repeat as required.
But as Andrew pointed out it uses a narrow-band O2 sensor, so it is not great. I have a PLX wide-band O2 sensor that also has a narrow-band output that feeds the input to the EM2. I can't say for sure but it did seem to give a more responsive signal to the EM2, which improved the auto tune. But as it also gives a very accurate and responsive wide-band output to it's own display, which is essential for fine tuning manually.

OK, looked in EC2 source code, last comment ;10-09-05 (Oct 2005), so I
doubt it.
There's also source code for EC2F, what ever that is. Latest comment
there is ;03-16-12

No mention of auto tune in either.

I could be wrong.
