Frequently asked questions

From the factory, your vehicle’s computer is calibrated for the masses, designed with the average driver in mind, not the performance enthusiast. This not only leaves valuable horsepower & torque hidden inside your vehicle, but it also makes for a mediocre driving experience.

It supports multiple tune files, datalogging, real-time parameter adjustments, and easy return-to-stock capability. Pre-loaded with base files, but shines with 5 Star’s custom tunes for your exact modifications.

Benefits:

  • Increased horsepower and torque across the RPM range
  • Improved exhaust note with reduced restriction
  • Better towing performance and daily drivability
  • Easy, at-home installation and tuning—no trips to the dyno required for basic setup

What Is the Process With PCM-F0-MG1-U?
HP Tuners is pleased to now offer an upgrade service for the MG1 PCM found in 2021-2022 Ford F-150 trucks powered by the 3.5L and 2.7L EcoBoost V6 or 5.0L V8 gas engine. This service enables full functionality of VCM Suite software custom tuning using an RTD+ or newer generation interface. This one-time upgrade service upgrades your original Ford MG1 PCM requiring you to remove the original PCM from your truck and send it to our headquarters for servicing (see shipping information below). After upgrading, we’ll ship it back to you and you’ll have full access to calibrate, log, and scan via the OBDII port using the latest version of VCM Suite.

No relearns/reprogramming required (see important notes):
No IMMO relearn*
No crank relearn*
*As long as the PCM is installed back into the same vehicle it came from.

Ford MG1 PCM Service:
PCM (Ford MG1) License for tuning: (4) Universal Credits (Included with the purchase of 5 Star Tuning RTD+ or 5 Star Tuning email tunes)

Important Notes:
This service is required to tune 2021-2022 F-150 trucks with the 3.5L EcoBoost/2.7L EcoBoost/5.0L gas engine and MG1CS036 PCM using VCM Editor.
This is a send-in upgrade service that requires the original PCM to be removed from the vehicle and sent to HP Tuners for servicing.
Expect 1-3 business days for servicing (not including shipping times).
PCMs with broken tabs or connectors WILL NOT be accepted for upgrades. No exceptions. Please be careful when removing your PCM.
This service only upgrades your original PCM for tuning, it does not reprogram your PCM for a different VIN. If you intend to send HP Tuners a spare PCM, it will be returned to you with the same programming as it was received and may not operate in your Ford vehicle without additional programming by a Ford dealer.
Your MG1 core must be fully functional with no physical or internal damage.
No other tuning or calibration tools can be used with the PCM (including dealer reflash tools).
VCM Scanner, Dealer Diagnostic, and other diagnostic tools will continue to function normally.

How It Works:
Step 1: Once you’ve confirmed your vehicle’s support (2021-2022 Ford F-150 3.5L EcoBoost/2.7L EcoBoost/5.0L with MG1CS036 PCM), purchase this service.
