Scangauge can display LTFT value. I have one and clearly saw difference between running stock intake and AEM (i have 2006 xB)
AEM intake is slightly smaller diameter than stock runner which makes the MAF readings be higher than what they should be. So my ECU learned to run -5 to -7 Long Term Fuel Trim once it's off idle. With stock intake before it usually ran between +2 and 0. Last edited by Reactor; 10-25-2011 at 01:04 PM. |
