Title: Fuel dump after gear change or sudden WOT in higher rpm causing slight bogging Post by: elRey on June 29, 2014, 07:25:19 AM Ok, I'm getting fuel dump from some where, but it's NOT reflected in desired AFR.
Right after a gear shift during a run or suddenly going WOT both in the upper RPM (>4500), desired looks fine (mid 12's) but actual pegs lower limit of 11.025 for a sec then comes back up and stabilizes. During this fuel dump, the car feels like it boggs down. I've ruled out ESUK - rkukg_w and rka_w. I'll post logs later. Thanks in advance.

It sounds like it's related to load transitions. Title: Re: Fuel dump after gear change or sudden WOT in higher rpm causing slight bogging Post by: elRey on June 30, 2014, 05:44:46 AM made rkukg_g = 0 and b_bag = 0
Still got had fuel dump and bogging. Title: Re: Fuel dump after gear change or sudden WOT in higher rpm causing slight bogging Post by: prj on July 01, 2014, 12:23:15 AM Too small dump valve possibly causing reverse flow through MAF.
