For a low introductory price of $249, the QuarterHorse delivers in unparalleled fashion. It gives you absolute, bumpless, 100% realtime tuning AND realtime datalogging for all EEC-IV and EEC-V through 2004. It plugs into the J3 port like a chip, but its capabilities are stunning. This is just the hardware, and limitations of vehicle coverage are only with the software packages (which are evolving quickly and available separately).
You can change ANY parameter while the vehicle is running without disturbing operation. You can log ANY parameter in RAM from the EEC-IV and V at sample rates well over 2,000 frames per second through the same mini USB cable (no OBD cable needed). Simultaneous ultra-high-speed rigorous datalogging capabilities are closely-coupled with the realtime-emulation / tuning-on-the-fly for the ultimate tuning experience.
This device continues the tradition and heritage of our highly-integrated, low-cost, high-quality tuning tools from GM and Honda into the Ford arena. It is fully supported by all the major DIY-EFI software such as Paul Booth's EEC Editor, Clint Garrity's Binary Editor, and Mark Mansur's TunerPro.
The QuarterHorse does have limited support (4x) for remote switching via rotary knob (available separately) as well as software-based program selection from PC (8x 1-bank, 4x 2-bank, 2x 4-bank). It does not support reading of the EEC port to harvest 'stock' binaries.
Comes with the QH device, premium USB 2.0 mini-to-regular USB bulkhead cable, cable mounting bracket and bolt, standard USB 2.0 cable, and 2x snap-on ferrite beads. Software available separately (check the Moates.net Software and Drivers section).
