Areas We Address with Custom Tuning

Fuel tables are modified for either better economy or all out performance. Depending on your needs is how most tables are set up. We have noticed on the Ecoboost Mustang that the fueling tables are very conservative and rich in their strategies and have long delay timers set before allowing additional fuel. Long fuel delays create issues with additional power and torque improvements. However, some fueling delays are ok as they help with economy.
The Ecoboost Mustang suffers from poor throttle response down low. By correcting this issue and a few others; improvements will be much better throttle response, step on go pedal, vehicle will respond quicker…this DBW system is a torque driven system, it works by taking a certain amount of torque via engine and wheel and applies it to what the driver foot say it needs; a better way to explain it is its a torque limiter. It only allows so much torque at a given pedal position. Stock tables are conservative and numb at best and that’s why one would feel some times a lag or a goofy pedal with DBW systems. For a Ecoboost Mustang this is one of the most critical areas that must be addressed and modified to generate more torque /hp and throttle response. By reworking the OEM strategies makes your Ecoboost Mustang come to life!
There are normally 3 types of limiters on most vehicles and the Ecoboost Mustang is no different. RPM, MPH and transmission Output shaft limiters are slightly increased to a safe limit in our calibrations. We can also leave the factory limiters in place what Ford has set from the factory based on customer requests.
Can be increased in most RPM areas for improved Torque and HP. Running a higher Octane fuel will net more power and economy from some timing/spark advancement.
The Torque Converter strategies can be reworked to lock up sooner and stay locked longer at light cruising speeds to also help with economy…A locked converter is power to the ground.
We use a custom shifting and converter pattern if you have an Automatic transmission in your Ecoboost Mustang.   This gives you a great daily drive with the FUN factor.   The Sport Mode is also enhanced for better and more precise power to wheel.
Shift pressures are  increased and slip timers can be decreased to help keep trans temperatures down and give the Ecoboost Mustang a better overall feel. In a Ecoboost Mustang shifts are quick and slightly firmer most of the delay between shifts are eliminated when using custom tunes.  Example under about 3500 RPMs shifts are smooth but above 3500 RPM the shifts are firm and have a sporty feel to them.
The PCM Ecoboost Mustang has to be read with the device once you receive by plugging into the OBDii port (Inside Cab Under edge of Drivers Dash) . We need the Part Numbers off the PCM that the device displays under Vehicle Info Menu (example GR3A-14C204-HB) or ECU STRATEGY SGBP2AS. Once we have these part numbers we can then develop your Ecoboost Mustang calibrations and email them back to you to download onto your device.
