On lots of ECUs, (MED17.5.25/21) for example, LAMFA is disabled and no matter what you change it to it wont affect AFR, it Will run 14.7 until BTS lambda map is active, i just maintain LAMBDA BTS active all of the time by changing mínimum temp for component protection and setting it to 0 so its always active and the you can control lambda perfectly with BTS maps and with better resolution

No.

Also ditch the greddy.

If the LAMFA module is in the binary then it is no problem to enable it.
Just because you don't know what to do doesn't mean "no matter what you change".
Read the FR and log with a ram logger, and the "impossible" becomes possible.

So this here is 100% misinformation.

As for the OP - is the map even defined properly?
You did not mention what ECU you have or anything of that nature.
Also, this is not how you tune the LAMFA map. You destroyed your fuel efficiency after 3800 rpm basically for no reason.

understanding the relationship between IOP/IRL is all you need.

There is an exhaustive explanation in the s4wiki

Logging all of the applicable vars is tricky since ME7Info doesn't find them all.

disassembly or possibly the various tools from prj/trev may help

No don't edit random things. Why would you do that w/o any evidence whatsoever that that is your issue? I also doubt whatever you changed made any sense since you didn't say what problem you were trying to fix.

You didn't post logs.

You certainly didn't post how you found the rest of the torque RAM locations. All of this is necessary if you expect to be able to tune IRL/IOP past the very basics.

RAM locations are not map locations. They're for logging.
