Got a 2011+up F150 3.7L V6

Some of the general areas that we address in our 3.7L V6 calibrations strategies are as follows below:

5star-3.7l

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 3.7L V6 that the fueling tables are a little on the lean (yes lean in stock form) side in stock form 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 3.7L F150 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 3.7L V6 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 3.7L V6 come to life!
There are normally 3 types of limiters on most vehicles and the F150 3.7L V6 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. However, with a 3.7L V6 even running 87 Octane fuel can yield some respectable gains in power and torque over stock. The knock sensors and strategy on the 3.7L V6 are very good in that they can advance and retard timing while you drive.
In all F150 3.7L V6 vehicles 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. Some times a stock truck when you hit any incline the truck will unlock OD gear and down shift. We can get your truck to hold OD longer and not unlock… now of course on large hills it will down shift…like it should…
The 6 speed transmission that comes standard with the F150 3.7L V6 is a big improvement in driver controls over passed 4 speed transmissions. However, there are still some major benefits to be had recalibrating normal daily shift strategies.
We have noticed that while in normal everyday mode that the transmission will move into 6 gear really quickly around town with speeds as low as 35-38 mph this really lugs the engine and when trying to accelerate there is a pretty good delay to either downshift or accelerate. We can correct this by moving some shift strategies patterns around in all gears especially in 5th and 6th gears.

In the tow/haul mode the Factory strategies in are very inefficient. 6th gear is useless under 60 mph. In the 3.7L V6 there is little engine braking in stock form while in tow/haul mode. Coasting or slowing down the downshifts don’t command soon enough to slow truck down and downshifts don’t command soon enough to keep the RPM’s up in torque range and when back in throttle multiple down shifts seem to occur. Gears 2nd, 3rd and 4th are the gears the truck likes to run at under 60 mph towing 5000lb but its in 6th gear at 50 mph lugging engine. Once RPM’s builds to 3000 plus the truck pulls like a champ but factory strategies keep RPM’s low. For owners of F150 3.7L V6 going to tow trailers at 5000 lbs the factory strategies will hunt all over the place in tow/haul mode. We have recalibrated tow/haul mode strategies that enhances keeping the engine RPM’s elevated to take advantage of the torque band in this 3.7L V6 less downshifting and taking advantage of gears 2nd, 3rd and 4th more. All of our calibrations have this new tow/haul strategy except economy mode calibrations.

Shift pressures can be increased and slip timers can be decreased to help keep trans temperatures down and give the truck or any vehicle a better overall feel. In a F150 3.7L V6 shifts are quick and slightly firmer most of the delay between shifts are eliminated when using custom tunes.
The PCM (computer) F150 5.0L truck is located in the engine bay on the fire wall on passenger side. Look for a white sticker with 3 letters and 1 number on it, that is the vehicles PCM Code.

Custom tunes allow for many choices when it comes to tuning your vehicle. 5 Star Tuning will be offering these popular choices for the new F150 3.7L V6.

Our Custom tuned devices will come with 3 of these Performance Calibrations; which will have all the enhancements completed in Engine and Transmission functions. This includes Drive By Wire, Fuel, Shifting, and Torque Converter strategies. These performance calibrations can increase economy the trick is staying off the go pedal.

You will also get user options with each of these tunes as well, so you can change stuff like timing, shift pressures or fueling.

CALIBRATIONS that are available for your F150 3.7L V6 are:

87 Octane Performance/Tow
87 Economy
89 Octane Performance/Tow
89 Economy
91 Octane Performance/Tow
91 Economy
93 Octane Performance/Tow
93 Economy
