Title: S4 B5 Trackday car fine tuning Help Post by: tkla on February 13, 2025, 05:51:40 PM Hello, my project car is an Audi S4 B5 2001.5 stage 3
I did an upgrade to 1000 CC Bosch 0280158117 injectors and now I am not achieving the requested boost. This car is a trackday car, so I removed almost everything for the car. I pulled a couple 2nd gear logs due to traffic, however it reflects the same behavior as in 3rd gear. IMPORTANT MODS (The car has more ask if you need something else please) M BOX EV14 BOSCH 1000 CC INJECTORS RS4 MAF HOUSING (Hitachi) ALTTITUDE 2400 METERS ABOVE SEA LEVEL WEATHER 25 CELSIUS. AEM WMI PUMP GAS 91 OCTANES. RS6 K04-25 TURBOS. ABD MODULE REMOVED. VCDS Soft coded N80 REMOVED However N80 wiring DTC is present. OE Engine Attached find logs and current Map if you could help me I will appreciate it a lot Title: Re: S4 B5 Trackday car fine tuning Help Post by: nyet on February 13, 2025, 05:56:47 PM log all PID variables.
If i had to guess, your WG's are set too soft and you'll have to modify KFLDIMX and/or KFLDRL accordingly. Consult the tuning page.

I did a slight mod in KFLDIMX and/or KFLDRL. Here is a log with PID variables, if there is something more to log let me know. Title: Re: S4 B5 Trackday car fine tuning Help Post by: tkla on February 14, 2025, 03:34:48 PM In Action

something very wrong with your setup. bad n75, wg not adjusted etc. hopefully not a boost leak. |
