IEGO and HEGO

Post by Pullmyfinger » Mon Sep 14, 2015 1:22 pm

Are IEGO and HEGO the same thing? I am data logging an existing tune, and am seeing IEGO at between .78 and .85 throughout the RPM and load profile, with a LAMBDA of 1 across the board with the exception of WOT during which it will drop to about .97. I want to make sure IEGO and HEGO are the same thing before I start messing with this.

thanks,
