Shift Strategies: The 10-speed transmission that comes standard with the F150 5.0L V8 is a big improvement in driver controls over prior 6 speed transmissions. However, there are still some significant benefits to be had re-calibrating normal daily shift strategies.
Daily Mode: We have noticed that while in normal everyday mode that the transmission will move into 8th,9th, 10th gears really quickly around town with speeds as low as 42 mph this really lugs the engine and when trying to accelerate there is a pretty good delay to build boost and either downshift or accelerate. Also, Ford is skip shifting in normal mode as well. We can correct this by moving some shift strategies patterns around in all gears. Our calibrations will have an emphasis on shifting at the right mph and rpm as to take advantage of the low torque that is available from the 5.0L V8 engine while maintaining great fuel economy and power to accelerate when needed.
Tow/Haul Mode: Coasting or slowing down the downshifts don’t command soon enough to keep the RPM’s up in torque range and when back in throttle multiple downshifts may occur. Also, keep in mind engine braking; a V8 engine has less braking that Ford’s past V8 engines larger displacement, so a quick downshift for braking is required for owners that are going to tow heavy. We have re-calibrated tow/haul mode strategies that enhance keeping the engine RPM’s elevated to take advantage of the torque band which will require less downshifting by optimizing gears. We have also enhanced the downshift patterns to allow better engine braking with this V6 engine. All of our calibrations have this new tow/haul strategy except economy mode calibrations.
Sport Mode: is a fun mode in factory form but does not have much use in a daily drive except wide open throttle. We have an enhance shift pattern that allows you to take advantage of this sport mode to make use of it during your daily drive when you want both sport and fun with keeping some of your driveability in mind. Upper gears 8th, 9th, 10th are much more driver-friendly after tuning being able to get into these gears at an except-able MPH is key.
Economy Mode: The throttle is desensitized and the shift pattern is reduced with locking the converter up in most all gears and keeping it locked as long as possible to get the most efficiency from your vehicle. All of our Perf/Tow tunes/maps will have this eco mode and should use when wanting the best fuel efficiency.
Snow/Wet Mode: The throttle is desensitized and the shift pattern is reduced with emphasis on maintaining traction in snowy or wet conditions.
Shift Pressures/Slip Timers: 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 an F150 5.0L V8 the shifts are quick and slightly firmer most of the delay between shifts are eliminated when using custom tunes.
