Occasionaly seeing the same after upgrade to 1.1.88
IAC goes on with ignition jumping up and down 10-20°, specially felt at low rpm and causing "kangarooing" when i release the clutch.

Now i'm also getting suspicious if its going on during cruising, causing higher EGT and increased consumption than before upgrade.

Need to get back to this more i think...

 >:(  I got something similar on 1.1.88 ! Engine runs good during two weeks. And suddenly after hot restart IAC flag was ON always (except may be overrun). I downloaded config to PC, comparing it with previous - and it was exactly the same - no single sign difference!

Also I had bad luck with 1.1.88 on Subaru with stepper. IAC flag was so unpredictable - I was forced to downgrade to 1.1.85 or 81...

I've been OK on the 1.1.88, if it did it on the race cars I'd notice. Strange.

You could post it on my wiki page. 

They replied yesterday saying it is fixed in 1.1.92

Any luck with 1.1.92?  Problem has been gone for a while here, but seemed to be back today.
I hope that upgrading does not lead to other issues then..

Btw. i put VEMS stickers on the car today, so  it can't be all that bad  ;)

If you  read the wiki page linked in the first page, you'll see that setting "IAC close min map" to highest possible value negates any effect even if you continue to run the older firmware.
