I'm sure there are more....thats just one I found that I needed to get this car to idle correctly...
would not idle down lower than 1200 no matter what I put in for idle airflow.....then I found the file that was originally in it and proceeded to use and modify it because it had a -10 and had zero issues getting down to commanded idle around 700 rpm.
copied over all of my stuff into it leaving the spark idle minimum at -10
it started as a file from somebody else, and was on an SCT box...
I turned it back to stock so they could sell the SCT box...and in the process lost that -10 variable...
thankfully I read the file from the ECU before returning it to stock.

I tested again on two cars, same calibration. No change in mixture when changing lwfm tables when maf disconnected. And no change when another available airmass tables changed.
Any news is this?
Another thing. MAF Temp Compensation, looks it works opposite like it's described. Values from tables are substracted from 1.0 and this gives final factor, not added. So positive values in table makes leaner, negative makes richer.

Is there any table that correspond for enrichement in cold condition and is hidden?
I have problems on 2 cars that they are to rich when wot when cold. No problem on N/A cars, due it makes richer from eg 12.8 to 11.5 or so, but when commanded afr is 11.5, it makes something like 9.5 and then it missfire, way to rich.
I checked all tables available with no results. Airmass tables, transient fuel tables (even zeroed them all).
Some help makes MAF Temp Compensation, but when car is hot, air temp is still same and then it's to lean.
It's not injectors related, due one car is dual fuel, and second fuel is doing this same.
But he don't change commanded lamba, it's cold and hot as set in base fuel table, 0.79.
I tried also cold fuel table, but car never showed commanded lambda from this table. It always uses normal fuel table, no matter what enable and disable ect is.
I checked this on 2 cars.
Looks table like maf temp compensation but in function of ETC could help.

Do You have any info in my case?
FYI, i checked another mustang with different calibration and looks its this same, both cases. Enrichement when cold and not possible to change mixture in sd mode.
I don't totally understand your issue. There is some logic that can take place if the engine speed doesn't doesn't run up like expected, and the RPM adds some additional fuel because it infers that the fuel is of poor quality. There is a switch I can add in so that you can shut this logic off. I have it on my list of things to add.

First issue, make car running without maf with fuel trims at zero percent at close loop. Car will have no problem with stock cams. But with any others trims are usually more rich at idle. I cant change it with any available table.
Second issue, kind of enrichement at accel till car warms up. No problem hot, afr on spot. No problems on cold in close loop. Even i disable openloop completly, trims are on spot. Open loop enabled and its much more rich than commanded. Premium fuel 93 octane.
Same on stock car, but its not noticable, since its not commanded rich. This issue is definitely related to etc not iat.
Both issues will not be seen in 99 percent of cars.
Tomorrow i'll have another stock mustang, so i'll do additional checks.
