Title: simos18- reducing overrun fueling Post by: marchewa on March 02, 2023, 07:19:31 AM Hello, I have quite unusual problem as in opposite to everyone else I'm trying to reduce overrun "gurgling" sound. I have two cars- eu-spec octavia with chh engine and us-spec audi a3 with cnt engine. A3 overrun fueling is about 2-3x longer than in octavia. As a3 is decated this fueling is hearable and it just annoys me. I tried changing ENOS module maps but it solves problem only in stationary.
As I understand form documentation I'm playing with PUC state but can't find any map related to my needs. Also was looking for cat heating functions as US-spec have additional catalyst but also no luck. Could anyone give any hint how to solve it? Thanks.

PUC is when it's fully cut off. Title: Re: simos18- reducing overrun fueling Post by: EanDem on March 02, 2023, 11:11:35 AM You need to reduce duration of PU state. PUC is when it's fully cut off. Take look to clf_driv_mod_thr_open_puc_inh. |
