Lean code on 91? Log attached
Hi all, x-posting from another forum.
I started throwing a 2FC7 "mixture too lean at partial load" + limp mode on my 1er. I had thought I was running too my E for my setup, so I set FOL to 70 and went back to full 91 + Map4. Now, I can make this code happen on demand. 70%ish throttle, comes on as I start building boost - HOWEVER, when going WOT, the code will not trigger. I've managed to capture a log as the code comes on. The log ends a few seconds after the code is triggered. http://datazap.me/u/xer0-449/lean-co...&data=1-4-5-18 '12 N55 135i DCT | CP, DP sans kitty | 7" IC | PPK1 | PE | JB4 ISO | BMS OCC | BMS Intake |

my guess is some sort of boost/vacuum leak. could be o2 sensors and most likely something within the intake system. be sure to repost on e90 though. |
