Hi,

Welcome.

Map 4 is a safety map, meaning if something is really out of whack, the JB4 throws you to map 4 (stock like) to try & save the car from whatever is going on.

In your case- safety 2 = AFR LEAN.

You have some pretty large bank 1 to 2 AFR variances- I suspect an o2 issue.

Do you have any O2 codes? You will need a new O2 sensor.

Need to replace primary O2 sensor, not sure which one but I'd probably just do both.

Now, for some reason car started to somehow slip when shifting. even though I'm not pushing it at all and run map 4. it's like hesitating to shift gears. and this morning when i was driving like 10 mph it threw me trans malfunction.
(I always wait 2-3 min before I drive after start.)

O2 sensors should be replaced today.

Are you running a trans flash?

O2 codes / trans issues arenít related (you probably know this, but just throwing it out there lol).

Now I have another log to review.

Car was jerking under pedal around 30-40%
I changed menu 11 to 1000

now it seems ok, but on the speed around 80 mph under same 30-40% throttle it does the same thing.

I tried to log today, and then it also went to reduced power mode with codes
2D2E
30FE
3100

Ambien temp was around 88 F

car has AR ownpipes, ER CP w/tial, BMS DCI

if someone can advise me on this problem, please take a look at the log

Thank you

Also- work on NOT taking your foot off the pedal during logging, stay WOT

Also- remember it’s Sunday- lot of the regulars are with family etc.
