Post tune and log file so I can check it here. I don't have any M30 ECUs to check on however I have a damaged one I can send you. I think it got a little corrosion inside it. Started keeping #1 injector open. If that interferes with bench testing I could probably buy a good working one to send you.

These are a low sale ECU so are low priority when it comes for looking for new maps. It all depends on time available understood, if its on your to-do list (no matter how far down) I'll hope for the best. Out of curiousity, what is your highest selling? I imagine its also your most developed as well?

So what's my next step? Finding a way to disconnect my Knock sensor? Zero all the knock settings and take a log?

The tool tips say greater/lesser than 15c(59F) so In the morning I will plug this in and see if it allows real time changes below 15c(59F) and report back. Cold start and Warm start Maps now respond to real time changes based on startup temp.(Highlights are correct too). Good timing on this one as ...

I made the changes you mentioned. The screen shot shows the stock cold enrich next to my warm enrich table. Value of 15 puts me about 12:1 and the cold enrich table is dramatically richer. Based on the temps shown I think this is exactly the behavior I'm getting on cold mornings. Temp enrich capture...

I can totally see why it would have a different enrichment table for colder start. Engine may be warming up but if its still sucking in freezing ambient air a little more enrichment is necessary. I thought I saw 9.7:1 the other cold morning and richer and I think the engine will stumble. My injector...

I found an older adr from a backup and did a side by side.
Left is old march 2015? Right is dated 9/2/2019 when I can get back to the car I might try reverting to see if it helps (or if I've always had this problem, I didn't mess with timing when I was running the stock MAF)

I've seen some of those in the .adr but I'm not sure where I'm going with them.

Timing is being pulled when engine fully warmed up.

I did see that the M30 adr references the BASE_RB20_VG30_256_E.adr (so that's where some new maps came from after an update) has a parameter there changed ?

I did see

#Not used

...

COLD_START_ENRICH,&H0000,0,0,0,0
WARM_START_ENRICH,&H0000,0,0,0,0

Would it be as simple as moving one of those lines to this area? or do I have to turn the zeros into some other numbers first?

#Additional maps
TEMP_ENRICH,&H7EB0,16,1,16,1

Quick check this morning:
-- 46F started ran 11:1, zeroe'd highlighted cell and adjacent: no change.
-- shut off engine at 72F, let ecu power down
--Restarted engine (80F) ran 13:1 per the map, zeroe'd highlighted cell and adjacent: Real-time change reflected 14.9:1~15:3 AFR

I think I figured something out, I believe they're used to be multiple enrichment tables for cold start and for warm start... It wasn't very cold when I took a log yesterday but it was cold enough for me to see the fuel ratios were not following the temp enrichment table and changes made to the high...

I'm not familiar with setup, but the M30 ECU should run same as factory with the Nistune board installed, if it is a different vehicle/engine then some M30 specific operations might work differently? We don't have a board for the engine you mention Log of warmup would be helpful I feel like not the...

There is not much more that can be done unless the idle stabilization tables are identified. However the M30 VG30E code is quite different from RB20DET so that would be difficult Today was colder AAC pulled up to 1800 RPM in the parking lot getting to work. I don't know if this helps but the AAC re...

I highlighted my whole main timing map and subtracted 5 today. No change in its behavior. But I looked more closely at the trace and today it looks like its only happening over 3k RPM. I will try setting all knock maps to zero. There seem to be several that read in different ways. not sure how they ...

If I run a log is there a particular thing I should look for?
I'll follow timing vs TP and RPM and see if I find a connection.
