Title: 1.8t CFMA Stage 1 log analysis
Post by: Maciek-Jura on December 28, 2025, 11:02:52 AM
Hello i'm playing around with tuning my car and here is my log. There's ignition retard on cylinder 3 and also why doesn't engine load reach the required value? Any help finding reasons would be appreciated. I'm attaching two files one with raw data and one that i processed.

charge pressure doesnt meet request so the load
PID should be tweaked a bit

you didnt log pid vars but the ldtvm spikes on the chart say it all
