Lots of rumors surround the current situation as to if aftermarket tuning devices are detectable
in the new 6.4L Powerstroke Diesels. For most devices on the market, the answer to that

question is YES. Ford Motor Company has special algorithms in place within the factory

computers to detectthe download of a program from a non-Ford programming device; which

triggers the diagnostic troublecode "P167F", defined as "Non-OEM programming detected."

This code is only viewable with Ford dealer or Ford Engineering diagnostic equipment, and will

not be read or cleared by any other tuning device or diagnostic code reader on the market.

This code is also stored in multiple computer modules scattered about the vehicle, meaning

that "clearing" or resetting the engine controller alone will not force the code to go away.

 

Other in-line devices (tuning devices that plug into the engine harness connections rather

than being downloaded as a programmer) claim to be undetectable since there is no actual

download of a program through the computer system. However, this is not true, as the

factory computer(s) collect and store information from the engine in the form of

"freeze frames". These freeze-frame data collections WILL show evidence of the use of any

in-line tuning device even after the product is removed from the trucks. And unlike

previous model trucks upon which the computer can be "cleared" by the practice of

removing/unhooking the battery cables, all information on the 6.4L vehicles is stored in

"non-volatile" memory, meaning the information is stored permanently until overwritten.

A traditional "reset" cannot be performed, meaning the evidence of use of a in-line device

will be shown to any Ford dealer or Ford engineer for a very, very long time.

 

Our tuning devices use a proprietary process when saving the stock tune and downloading

our custom tuning to "emulate" the presence of a Ford factoryprogramming device. In

doing so, the presence of the "P167F" diagnostic code is prevented. Likewise, when a

vehicle is returned back to stock using our device, multiple computer modules are internally

reset to prevent and delete other tell-tale evidence of aftermarket tuning. This gives our

Spartan Phalanx programming device the highest level of undetectablilty available on the

market, helping to preserve your factory warranty and preventing warranty denial by Ford.

As Ford truck owners ourselves, our crew members share the concern about preserving

factory warranty and understand the stress involved when choosing an aftermarket device

in this respect. This is why we take every measure to protect our customers' confidentiality
and spend tremendous development effort to do so.
