M135i JB4 not showing AVG_IGN

New to the N55 game but an old hand at the JB4 and N54...

Just got done installing my JB on my 2014 M135i (EWG).The car is stock other than the JB. EWG harness and Flex Fuel harness are installed.

I noticed that in the initial few runs on Map1 pre-logging the car felt very weak, but as I started logging I noticed things improving and boost sitting around where I would expect it. I also noticed that the car is not calculating AVG_IGN?

Any idea why this may be? Any logs ive found over at N54tech seem to have AVG_IGN values regardless of the map used.

Map 5 adjusts AVG_IGN up to 5ish after a few pulls. Pretty damn high :(

I wonder why it doesn't bother calculating it on Map 1 as I've seen with others' logs.
If you are using Tesco Momentum 99 Ron fuel only then you should see between 2.8 and 3.9 at least I did.

My avg_ign used to work with positap and old firmware but it's now blank.

Going to try setting map 5 to see if it shows up in that map butcits very weird.

Loving the OBD connection though and oil temp. :)

Edit:

Avg_ign is back it seems you have to select Map 5 once for it to show up and then it will change as it adapts in map 5 and map 6.

Established the cause some time ago (that it was only calculated on Map 5 with the firmware I was using).

AVG_IGN is however now calculated in all maps as of the v6 firmware update (which you should skip in favour of v7).

I'm unsure what firmware I am on I would presume it's the latest as I just got a new F series JB4 unit.
