AREAS WE ADDRESS
Fuel tables are modified for either better economy or all-out performance. Depending on your needs is how most tables are set up. Most vehicles that go into Open Loop use this fuel table for its fueling requirements. Most Ford Sport Vans will not step up into Open Loop (power enrichment) at WOT and from the factory are calibrated to operate in Closed Loop which restrains power levels. By correcting this power enrichment function alone can increase power and torque from your Ford Sport Vans.
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 Sport Van this is one of the most critical areas that must be addressed and modified to generate more torque and throttle response. By reworking the OEM strategies makes your Sport Van seems as if 2 more cylinders were added over night!
There are normally 3 types of limiters on most vehicles and the F150 5.0L 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. However, with a Ford Sport Van even running 87 Octane fuel can yield some respectable gains in power and torque over stock.
In all Sport Vans 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…
On the Sport Vans 5 Speed Trans the Ford Strategy is to NOT use all 5 gears in the Torq Shift transmission. Hard to believe I know. In non-tow/haul modes Ford uses only 4 gears when going up through the gearbox. With a custom tune from 5 Star we will use all gears in our shifting and torque converter lock strategies. You will also see quicker shifts, as the truck will proceed into OD quicker than stock strategy. This will provide better power and economy out of your Sport Van.
Can be modified to an economy or towing calibration. An economy calibration up-shifts will be sooner. Towing calibration shifting will occur higher in the RPM ranges to keep vehicle from lugging and take advantage of the engines peak torque. In vans that do not have Tow/Haul mode this can be beneficial when towing. On the vans with the 5 speed trans, the Ford Strategy is to NOT use all 5 gears in the Torq Shift transmission. Hard to believe I know. In non-tow/haul modes Ford uses only 4 gears when going up through the gearbox. With a custom tune from 5 Star we will use all gears in our shifting and torque converter lock strategies. You will also see quicker shifts, as the truck will proceed into OD quicker than stock strategy. This will provide better power and economy out of your van.
Shift pressures can be increased and timers can be decreased to help keep trans temperatures down and give the truck or any vehicle a better overall feel. In a Sport Van shifts are quick and firm most of the delay between shifts are eliminated when using custom tunes.
Where do I find my ECU Strategy Code?
At the time of your order if your ECU strategy code is known, we will send your tuner loaded with tunes on your selected tuner. If this information is not known at the time your order is placed, you will be provided a blank tuner to acquire the needed vehicle information.
If using an SCT or Bully Dog Device: On your device under vehicle information, you will find your ECU Strategy Code. An example of an ECU Strategy Code for 1996-2014 models is PKRK0R2.
Custom tunes allow for many choices when it comes to tuning your vehicle. 5 Star Tuning will be offering these popular choices for Sport Vans.
Our Custom tuned devices will come with custom 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 Sport Van:
87 Octane – Economy
