Car: '18 340i
Default 340i switched from map 5 to map 8 while logging - 08-07-2020, 02:13 PM

I was doing some logs since I added the EWG harness. Cars been running fine for a week, and logs looked good. While logging today tho, the car switched from map 5 to map 8 in the middle of the run. Looks like it went lean, not sure why though. Any ideas on what could’ve caused it? Running E40 mix with 91, EWG harness, *** less dp, and intake. Thanks in advance!

Last safety in the log tells you why it changed to map8, looks like the lean AFR and maxed out fuel trims.

Will need to lower E85 mix or add in our back end flash to rescale those fuel trims.
