⚠ CRITICAL: TCM — U0101 Lost Communication
⚡ HIGH: Bank 2 LTFT +9.8% — lean condition
⚡ HIGH: 23 knock events detected — timing pull active
ℹ INFO: TCC slip 180ms avg — monitor
GREASE: The U0101 is your primary concern. Combined with the bank 2 lean condition, I'm seeing a pattern consistent with a loose TCM connector or failing CAN termination resistor on the HS-CAN bus...

Built for the tech who gives a damn.

Not for the parts-changer. For the tech who wants root cause, not guesses.
