GM Duramax 6.6L E86 ECM Cloning Service

GM Duramax 6.6L E86 ECM Cloning Service

For 2011–2016 E86 & E86A ECMs

If you’re replacing a failed or damaged ECM on your Duramax 6.6L (2011–2016), our E86 ECM Cloning Service provides a seamless plug-and-play solution. We’ll duplicate your original module’s critical data — including VIN, immobilizer, and operating system — to a donor ECM, eliminating the need for dealer programming or re-flashing.

What We Do

We professionally clone your original GM E86 or E86A ECM to a replacement module with matching service numbers. This means your new ECM will function just like the original — no additional setup, programming, or HP Tuners licensing required.

This service is ideal for:

  • ECM hardware failures

  • Swaps or rebuilds where programming access is limited

Important Requirements

🔧 Service Numbers Must Match
Both the original and donor ECM must have identical service numbers. Mismatched part numbers will result in a failed clone and delay the process.

🚫 We Do Not Supply ECMs
This is a cloning-only service. You must provide:

  • Your original (bad) E86 ECM

  • A matching donor ECM in good condition

What’s Included

✅ Full data clone (VIN, IMMO, OS)
✅ Plug-and-play ready
✅ Safe, tested cloning process
✅ Quick turnaround

Disclaimer: Some ECMs may require the rear cover to be removed during cloning. This is completely normal and does not affect function but may result in minor cosmetic changes.

Supported Applications

We support most 6.6L Duramax platforms using E86 and E86A ECMs, including:

  • 2011–2016 LML

If you're unsure about compatibility, just reach out with a photo or part number and we’ll confirm before you ship.
