I've attached my current tune file; i'll log my drive home and update with that (tried to log the drive to work but it didn't pick up my AEM AFR gauge).
The issue i'm running into is during a coasting condition the engine goes full rich and can cause my MIL light to pop on. At idle (stopped or parked) it runs fine to my commanded AFR and anytime i'm on the throttle it runs to my commanded AFR; however when driving and coasting down a hill or just off throttle while moving it'll go to a full rich condition. I assumed the DFCO would kick in and cut fuel while coasting, what else am i missing?
this is the first and only tune i've done so please explain in fluent dummy terms 2004 Silverado 1st timing edit.hpt
