Digital Universal EFIE - MAP/MAF/O2 EFIE

This device (“Digital Universal MAP/MAF/O2 EFIE”) can work with:
1 - 4 wires narrow band (zirconium type) O2 oxygen sensor (Output of the sensor 0 - 1 Volt) or with:"5 or 6 wires wide band (zirconium type) O2 oxygen sensor (Output of the sensor 0 - 5 Volt ) or with: "variable voltage MAP/MAF sensor" (Output of the sensor 0 - 5 Volt) or with 4 wires AFR sensor. (AFR - Air Fuel Ratio ) Comes with 1" x 2" x 3" black plastic box with velcro for easy mounting. All you will need is some wire and drill on hole for 4 wires : the + & - wires and IN & OUT to the sensor & ECM. See instructions link below.

This device has jumpers and buttons. Different position of jumpers and modes allow this device to work with different sensors. You simply re-arrange the jumpers and with buttons,  change to suitable mode. What Sensor is more preferable? Although the MAP/MAF Sensor gives advice, ultimately the O2 Sensor has the final say in the air fuel ratio. The best way would be to enhance the O2 Sensor and slightly enhance the MAP or MAF Sensor (about 10%).  Once you have it set there is no further tuning necessary.
 
Please pay attention:

This device can work only with one sensor at a time. One device per sensor allows placement flexibility during installation. Each device is tested before sale.
 
•    If you have one narrow/wide band (zirconia type) O2 oxygen sensor that to you is necessary only one device for O2 sensor and optional one device for MAP/MAF sensor.
•    If you have two narrow/wide band (zirconia type) O2 oxygen sensors that to you is necessary two devices for O2 sensors and optional one device for MAP/MAF sensor.
•    If you have installed the O2 sensor enhancer or O2 extender and did not see any changes that to you is necessary one device for MAP/MAF sensor.

What the difference between regular MAP/MAF Sensor Enhancer and this Universal MAP/MAF Sensor Enhancer? The simplest answer is: Linearity.

Regular EFIE is a divider, and this D-EFIE is a subtraction.

Features
1.    Soft Start Feature slowly increases the adjustment voltages when powered ON (For example: O2 sensor warm up delay).
2.    Option to disable and change time from 1 to 5 minutes on Soft Start Feature.
3.    LED’s light indicates when the power is ON and show delay time and current mode.
4.    Additional Terminal Block makes testing the voltages (offset, input and output) simple.
5.    Special circuit design eliminates variance of actual voltage output, input and adjustment voltage when using  multi-meter.
6.    Fine adjustable tune with a 4096 steps on full scale (0-5Volts). Each step is 1.22mV
7.    Normal connection from O2/MAP/MAF sensors to the ECU (vehicle computer) when power OFF.
8.    Low current consumption: 23mA (0.023A).
9.    Low linearity error. Max linearity error is 5mV (0.005V).
10.  Low temperature sensitivity +/- 2mV (0.002V).
11.  Operating temperature: -31F to 185F (-35C to 85C).¿12.  Small size: 2" x 1.5" x 0.6 (51mm x 38mm x 15mm).
Please note. The EFIE (Electronic Fuel Injector Enhancer) is not intended to be a fuel saver by itself. The EFIE is designed to be used only in conjunction with alternative fuel devices, such as a hydrogen gas electrolyzer, a propane, a fuel vapor production unit, or other alternative fuel devices that keep emissions with the EPA standards. (EPA Memorandum 1A).
All oxygen sensors that were developed before catalytic converter need own dedicated EFIE device. Oxygen sensors that were developed after catalytic converter don't need EFIE devices because they are only used by ECU to monitor converter fuel efficiency.
All parts and PCB is RoHS Compliant.
