Title: Help with ignition retards and low timing Post by: dmntr on October 14, 2025, 12:50:23 PM Hello everyone. I really need the help of the community with my problem. Have a Passat b5 1.8t 4B0906018DH ecu.
Chinese Jrone K04-15, turbo. injectors bex 0280156061 — 06A 906 031 BA. The main problem is ignition retards under load, and low ignition timing. I am attaching the latest version of the firmware to the post, .xdf and a log file made today. P.S. I know that the duty cycle of injectors after 5000 is more than 90%, but I'm more concerned about retards over the entire RPM range. |
