## What is td5comp?

Real-time diagnostics for compatible Td5 engine ECUs. Connect a compatible Bluetooth OBD adapter to communicate directly with your engine ECU.

FEATURES
---
Live Gauges
RPM, vehicle speed, coolant temperature and boost pressure displayed in real time like dials in your dashboard.

Sensor Data
Mass air flow, manifold pressure, intake air temp, fuel temperature, battery voltage, ambient pressure, EGR and wastegate duty cycle.

Cylinder Balance
Per-cylinder fuel correction for cylinders 1-5. View per-cylinder fuel correction values to help identify injector imbalance at idle.

Fault Codes
Read stored and active Td5 fault codes with descriptions. Clear codes directly from the app. Active and logged faults shown separately.

Accelerator Pedal
Track voltages across all three pedal position sensors and supply voltage.

Try Before You Buy
Verify your adapter works with your Td5 before paying. You only unlock full lifetime access once the data is flowing on your actual vehicle.
We recommend an ObdLink CX Bluetooth Low Energy adapter or similar. Other adapters may not meet the Td5's protocol timing requirements.
