Does this new version have other new features? I am looking for closed loop idle control. And am considering switching to Extra code.

I was hoping too much MAF is dead

Now I have found the problem it is:

12' MegaSquirt Wiring Harness has been wired incorrectly F-idle goes to pin 31 instead of pin 30 and IAC2B goes to 30. I connected MAF sensor to IAC2B and I am really hoping it did not get damaged...

On vehicle I get 7.4V even when i cut the Fidle wire ...
