Western Motorsports / Simple Digital Systems Programmable Fuel Injection System
Overview: Western Motorsports uses an SDS computer built specifically for their application. WMS then builds the wiring harness and lean/rich controller.
Latest News- WMS Wideband O2 sensor – a complete stand alone system using Bosch LSU4.2 sensor and Bosch calibration chip for accuracy. Included is
LED dash mounted display and datalogging software.
Information Source / Company Response- The information was supplied by Shannon Wall at WMS. The company was very responsive to my email.

Hardware
ECU – replaces stock ecu altogether. Wiring harness – Plug in versions to stock EEC-IV or EEC-V harness. Full harness version connects directly to injectors, distributor, sensors etc. LCD Programmer – All programming and monitoring of sensors is done in the supplied programmer, no laptop is needed.
Lean / rich controller – makes easy adjustments to fuel curve, very useful for tuning. Map sensor – 1 bar (naturally aspirated), 2 bar (up to 15lbs boost) or
3 bar (up to 30lbs boost) included at no extra cost. Low Impedence injector drivers – included at no cost if low impedence injectors are being used.
Software/Connection
No additional software is needed with the SDS as all programming and monitoring is done in the handheld programmer – no laptop is needed. Programming is far easier than most DFI systems as there is no complicated software to use. The SDS system is designed so the average person can tune the car themselves. A base program, based on your engine specs is installed initially so it will start up and run.
Hardware Designed for
Almost any application from 2.3 turbos, stock Mustangs to 1500hp race cars. Generally the tunability of the SDS can tame radical engine combinations to run on the street. Limits of the system are 30lbs of boost and 9500 rpm. Of course, you must have injectors and fuel system that is large enough to support the power.
Special Features
Each system includes the handheld programmer for tuning. All typical features are included in the system including rev limiter, boost limiter, closed loop control, fan control, fuel pump control, rpm output (shift light or other), anti-lag programming. High or low impedence injectors are supported. Only options that can be added are knock sensor and a backlight display for the programmer.
Datalogging
You can monitor all sensors in real time in the programmer. This includes rpm, air temp, water temp, injector duty cycle, boost, timing, tp, voltage. No additional datalogging is supported from the SDS computer itself. Our new Wideband O2 sensor does include datalogging software and can log air/fuel ratio and rpm to a laptop.
Additional Items Needed
An ignition box like basic MSD 6A, Crane Hi-6 etc are needed as an amplifier. The SDS controls the ignition and takes care of rev limiters, timing retard etc.
Support
Tech support is virtually unlimited via phone or email. System is covered by a 1 year warranty.
