System Requirements

You will need to have a Desktop PC or Laptop with a functioning USB, running one of the following Operating Systems:

     Win98SE requires a minimum of 24Mb RAM

     Windows 2000 and Windows XP (including Home editions) has a 64Mb RAM requirement

     Windows Vista & Windows 7 requires a minimum of 512Mb and 1 GB recommended

Suggested Optional Hardware

External sensors such as Wideband Air Fuel ratio, Boost or Fuel pressure will require additional hardware depending on year model vehicle and how many items you wish to log. 

On many EEC-IV based vehicles the EGR Valve Position (EVP) sensor can be used as an analog input, to measure a 0-5volt signal, like a Digital Volt Meter (DVM).  The output signal of many add on sensors will be scaled 0-1volt or 0-5volts.  This includes most Wideband Controllers used to accurately measure Air/Fuel ratios.  EEC-V vehicles do not have this specific extra input available.

The Original Equipment Manufacturer (OEM) Narrow band HEGO (Heated Exhaust Gas Oxygen) sensor used by Ford, can measure Air/Fuel accurately only at stoichiometric or 14.7:1.  Outside of that, the accuracy falls off very quickly, while being able to report rich or lean, they cannot measure how rich or lean.

Most wideband controllers measure Air/Fuel Ratios of 10:1 to 20:1.  When tuning a super or turbo charged setup, a wideband is required, if you want to keep the engine together.  

There is an external Analogue to Digital (A/D) converter that is supported and available for VERY reasonable cost.  The DataQ DI-145 (Avaliable 1st Quarter of 2011) gives the end user 4 external channels to log additional sensors.  This unit replaces the previous 4 channel serial port version.

The DataQ DI-148 gives the end user 8 external channels to log additional sensors and uses USB as its connection to your PC.  Using either unit will require at least two (2) USB ports be available, one for the TwEECer and one for the DATAQ unit.

USB Data Acquisition Starter Kits. Low-cost yet extremely powerful data acquisition starter kits featuring sample rates up to 14,400Hz.

We highly recommend wideband controllers from Innovate Motorsports and PLX Devices line of products.  Both companies are VERY reputable and stand behind their products.  We have heard nothing but good things from our customers who have been using these wideband controllers.  We have been using a unit from each of these companies (5+ years) and have been 100% satisfied with each.

The LC-1 is a complete wideband Air/Fuel Ratio sensor controller built into a sealed cable.

The PLX Air Fuel Ratio Sensor Module accurately measures the precise wideband air fuel ratio (AFR) of any internal combustion engine.
