SSM-NATIVE SUBARU TELEMETRY

SSM datalogging for Subarus.
Native on your phone.

FBKC, FLKC, DAM and per-cylinder knock at up to 10 Hz, over an OBDLink MX+ or Tactrix Openport. Pulls trigger on throttle and flag themselves on save. Alarms latch and can speak, so a knock event registers without looking at the screen.

WHAT IT DOES

Two jobs. One tool.

ON THE ROAD It watches so you don't.
KNOCKFlood, tone, and a spoken "Knock" with the cylinder — latched until it clears. Wrist buzz if you wear the watch.
PULLSArm on throttle, capture with a 2 s pre-buffer, save on lift. Zero taps at speed.
GAUGESBoost and AFR as error vs the ECU's own target — glanceable in direct sun, dimmed at night.
VIDEORecord the run with live engine data burned into the frame — RPM, boost, AFR, gear, speed on every clip.
HANDS-FREEVoice commands, volume-key mapping, watch gestures — log, mark, silence without looking.
AFTER THE DRIVE The answers are already flagged.
FLAGSEvery saved pull is auto-flagged — knock, lean, overboost — the moment it lands. Tap a flag, jump to it.
COMPARERPM-axis tracks line pulls up run to run — commanded vs actual, Δ vs last pull, knock heatmap.
HEALTHDAM history, FLKC learned cells, trims per bank — with a plain-language verdict.
REWATCHAlarm events drop chapter markers in the recording — jump the video straight to the knock, data on screen.

FEATURES

More in the box.

LATCHING ALARMS Compound rules with arm-conditions — judge AFR only under boost, for example. A firing rule floods the screen, plays a tone, and can speak a short phrase, then latches until the value returns to safe. Dry-run any rule against your last five pulls before saving it.
TRACK VIDEO Record from the phone camera with telemetry burned into the frame — RPM bar, boost, AFR, gear, speed. 1080p60. Alarm events drop chapter markers in the recording.
WEAR OS A companion watch app (Wear OS 3+, installed from the same Play listing): live ring with gear and the worst-severity channel, a wrist shift light (haptic at redline), a knock alert with tap-to-silence, and remote control — double-tap drops a marker, long-press starts or stops a log, every gesture remappable.
EVENT SNAPSHOTS Knock, a DAM drop, roughness or a DTC auto-captures a snapshot with a 2 s pre-buffer and 1 s post — the moments before the trigger are kept, not just after. Each snapshot links back to its pull.
ECU HEALTH DAM tracked across sessions, the FLKC learned-cell table by RPM and load, A/F learning per bank on a ±10% scale, and a plain-language verdict with suggested next steps.
TIMERS + VIRTUAL DYNO 0–60, ¼-mile and 60–130 with GPS cross-checked against wheel speed, plus a MAF-derived virtual dyno with SAE correction and per-car run history.
