Data and Connections

Wideband

• TechEdge 2J9 over serial: the AFR plus MAP, TPS, RPM and VSS through its analog inputs and counters
• The MAP sensor's voltage transfer (minimum and maximum volts against the pressures they represent) is set in Settings, so MAP is calculated with the right maths for whichever sensor you run
• A diagnostics window shows sensor health live: heater drive, cell resistance and lambda

ECU (optional, monitoring only)

• ELM327 adapter over WiFi or serial for live ECU data: spark advance, temperatures, injector pulse width, transmission, battery and more
• Purely for logging and keeping an eye on the engine's vitals; Auto Tuning never needs it
• The PID list is fully editable, and the poll set follows what the dashboard is showing
• The Dev tab's sniffer and PID Maker let you discover and add your own PIDs

Logs and sessions

• The built-in logger captures every channel plus the target AFR, zone and error for each sample at log time
• Stopping a log packs it into a .l2t session file: one archive holding the log, the profile, the learning database, the dashboard layout and the exact XDF and BIN that were loaded, hash-verified
• Opening a .l2t restores the whole session anywhere, dash layout included
• Logs recorded with TechEdge WinLog are fully compatible and load the same way as native logs
