Jeep Wrangler TJ 2004–2006 MANUAL PCM Replacement – NGC3 / SCI-B Protocol

• Configured to your VIN
• SKIM deleted by default (You can choose to activate or not)
• Plug-n-play

The 2004–2006 Jeep Wrangler TJ is well known for recurring issues with its factory Powertrain Control Module (PCM). At ECUHack, we’ve developed a reliable and long-term solution by identifying a compatible OEM PCM and reverse-engineering it to function flawlessly in these Wrangler models.

Unlike other options on the market, our replacement PCM is free from the chronic failure issues commonly found in the original units. Even better—it retains full tuning capabilities, allowing you to adjust fuel tables and engine parameters to suit your needs. This gives you both dependability and flexibility in a single upgrade.
