Default Strange Rich Region

Despite MLV wanting to lean out most of the table (which is correct) there are 3 or 4 cells that it has changed from 80ish to 120ish, which makes no sense to me.

I was running EGO controller authority at 10% and closed loop limit at 90 kPa

When things like that take place, i revert to hand smoothing to make things jive. Thats something i find with MLV, if it doesn't hit all the cells then i will finish the rest increasing or decreasing fuel according to what I know will be ok.

Same here, I have 9 points for the Idle and I always reset them.

I also find whilst MLV is awesome, it doesn't produce a smooth table. So i'll try to hand smooth it out.

I hand smooth it out in Megatunix tho, as the graphical display is far better than Megatunes. once done I revert back to MT tho, there's something about MTx I don't like...

fricking complicated, but it produced the nicest looking tables...

You should disable EGO correction, Accel Enrich, and Overun when you are logging.

MLV knows about them and ignores them

Do you enjoy creating controversy over stupid things? That link posted explains how MLV deals with those enrichments and 2 of the three are ignored while EGO is taken into account. You don't have to turn them off be MLV knows how to deal with EGO and doesn't care about the others. It does happen to be able to deal with the effects of AE and the rich mixture that is can create immediately after AE has worn off.
Either way, you can run with them on or off. It's personal preference because not everything always works the same for everyone. Some people swear that you should turn them off. Other's say it's unnecessary.

I have been turning all that off when tuning, probably because I use both auto tune and MLV so I didnt want to go back and forth between the settings.

But hey, its good to know you know.
