Diesel Technology 7.3L IDM Rebuild HVHC Service - 1994-2003 Ford F-Series

7.3L Powerstroke IDM High-Voltage / High-Current Upgrade & Testing Service (1994.5–2003)

If you’re experiencing injector misfires, rough idle, hard starts, or no-start conditions, your IDM (Injector Driver Module) may be the root cause. As these modules age, internal component tolerances drift, reducing injector voltage and current output. This service from Diesel Technology of Chattanooga restores and enhances IDM performance beyond factory specifications.

This is not just a repair — it’s a tested, proven performance upgrade designed to improve injector response and overall drivability.

🔥 What This Service Does:

• Fully tests IDM function and injector firing capability

• Verifies output voltage and waveforms using an oscilloscope

• Performs a complete rebuild as needed

• Upgrades injector voltage from 110V to 140V

• Increases injector output current by 20%

• Restores reliability while improving performance

⚡ Performance Benefits:

• Faster injector activation

• Stronger and longer poppet valve engagement

• Smoother idle and throttle response

• Improved drivability and acceleration

🧪 Testing Included:

Each IDM undergoes extensive validation, including:

• 20-point inspection on a custom-built test bench

• 30-minute stress test at 3000 RPM / 3.0ms injector pulse width
