If it's not really about tuning or wiring. Then it belongs in here.
Does any courses cover the graphing of EFI sensors and what to expect to see from a good or faulty sensor? Im using Texa Navigator diagnostics. Not for tuning but for fault finding
We don't really cover that specific topic in any of our courses. Generally if you understand the particular type of sensor and how it's used then you can normally have a pretty good idea of what the output from that sensor should look like. Can you give me something specific you'd like to know?
for the lambda sensors, when the bike goes in and out of closed/open loop would that cause the graph to flatline? both sensors look similar but another bike im working on just has highs and lows.
