JTEC PCM Tuning

Remote tuning for supercharged & naturally aspirated Chrysler/Jeep engines running the JTEC Speed Density platform.

I offer remote tuning services for JTEC-managed engines using HPTuners VCM Editor & Scanner. Whether you're running a stock 4.0L inline-6 or a forced-induction build with upgraded injectors and a 2-bar MAP sensor, I can help you dial it in.

What I Work With

• Jeep 4.0L inline-6 (and other JTEC-managed engines)
• Supercharged and naturally aspirated setups
• Upgraded injectors, MAP sensors, and fuel systems
• Manual and automatic transmissions
• Methanol injection integration

What's Included

• Base pulse-width table calibration
• Closed-loop and open-loop fuel strategy
• BARO, MAP scaling, and sensor configuration
• Power enrichment and transient fueling
• Idle tuning (including manual transmission swaps)
• Datalog review and iterative revisions

How It Works

You'll need an HPTuners MPVI2 or MPVI3 interface and a laptop. I'll send you a base calibration file, you flash and log, then send me the datalog. I review it, make revisions, and we repeat until it's dialed in. Everything is done over email.
