DCS is very pleased to support the use of the Ford 6.0L & 6.4L Automatic Transmission Control Module (TCM) with the Cummins conversion .
The biggest advantages of using the Ford factory TCM is that you keep the tow/haul functions, retain your factory diagnostics with regard to the transmission, and the stock shift quality adaptive function is retained. We recommend our tuning services for the Ford TCM to assure proper transmission operation and to get the most from your conversion. Be certain to complete your conversion, per our instruction manual, before driving your truck. A service fee of $450.00 will apply for the tuning support, plus a SCT tuner will also be necessary (DCS is an Authorized Dealer). We offer two different options; the SCT X4 and the SCT Livewire TS. Data logs recorded by the customer are required for our Tuning Technicians to tune your transmission to its fullest potential when mated with a Cummins engine. The data logs also allow the Tuning Technicians to confirm proper installation and all needed signals are present.
The SCT X4 Power Flash Ford Programmer is the base programmer we support. A desktop or laptop computer is required which allows you to receive edited transmission calibrations from DCS. If you do not have a Windows based laptop as described below you can buy an SCT Livewire. Remember whichever SCT module chosen, you will at least need a Windows based desktop computer to load custom tunes to your device and email data logs.
The SCT Livewire TS Performance Ford Programmer & Monitor can be used to log the transmission parameters necessary for custom tuning; Shift Points, Torque Converter Status, Transmission Temperature, Vehicle Speed and more. It also monitors Engine Coolant temperature and even EGT, up to 7 total analog inputs, with an additional $30 cable (not included). The Livewire is able to store custom calibration transmission calibrations, act as a performance calculator and a visual alert system for gauge limits.
Computer requirements for tuning: At least a Windows XP computer (Vista, Windows 7, and Windows 8 also work) with a minimum of with 200 MB of free hard drive space is needed to load custom tunes, data log, or to import data from the SCT Livewire tuner. All that is needed for the computer beyond the included tuner software is an internet connection and an email account to email the data logs and receive new custom calibrations. The software does not work with MAC computers at this time.
Q: Can I tune the transmission myself?
A: Due to the complexity and cost of the programming software user adjustability is not practical, although extra tunes may be ordered and flashed in whenever you want. Some parameters can be adjusted with the tuner, such as gear ratio, tire size and full throttle shift points, depending on the particular model of the truck.
Q: How long does the tuning take?
A: The time and number of tunes required varies. Don't be surprised if we have to send you several tunes. Each truck is a little different- one tune, even one that has worked in a truck just like yours, will probably not be enough to get your trans working with the Cummins engine as good as it can be.
Common problems solved by tuning are late shifts, flares between shifts, and late torque converter lockup. Beneficial tuning changes are available as well such as higher automatic downshifts in tow/haul mode, torque converter lockup in as early as 3rd gear and so on. You will need to record information as you drive the truck, also called Data logging, so our technicians can assess the performance of your transmission and make the appropriate changes. Be prepared for several data logs and new calibration files being emailed back and forth. We see a few as two calibration files or as many as six or seven, depending on individual circumstances.
Q: What will the total cost be for tuning?
A: Depending on the tuner you choose, you will pay $450 for the tuning service and at least $399.00 for an SCT X4 tuner. This is a combined total of $849.00.
Information on specific combinations:
The 2003 – 2010 6.0L & 6.4L Ford Diesel TCM option works great with automotive Cummins engines from 1989 through 2009.
