WHICH ONE DO I NEED?
That's a good question ( the needs vary with each car), but here is a general rule of thumb: Less than 4 wires into them they're narrow band (Dipped or Quad Efie), 5-6 wires definitely Wide Band (Wide Band Efie), 4 wires can be either way and should be checked with meter.
To see how and get more details- email for my free book on O2 Sensors and learn everything you need to know..
MILEAGE CHIP- If your car is 1996 or newer, you may consider using our new mileage chip which is even better, easier to hook up and adjust!

Single EFIE Basic (Dipped)
Retail: $69.95 SALE: $59.95
If your budget is tight, but you know you need an EFIE, this Single EFIE for cars with just one O2 sensor has the same guts as the deluxe without the added protection of a case and switch. There is still access to adjust voltage manually but meter has to be attached externally to wires. Good budget based Single EFIE works with all hho kits and hydrogen based generators. For use with ONE O2 sensor.

Dual EFIE Basic (Dipped)
Retail: $89.95 SALE: $79.95
If your budget is tight, but you know you need an EFIE, this DUAL EFIE has the same guts as the deluxe without the added protection of a case and switch. There is still access to adjust voltage manually but meter has to be attached externally to wires. Good budget based Dual EFIE works with all hho kits and hydrogen based generators. For use with up to TWO O2 sensors.

DIGITAL QUAD EFIE - BRAND NEW IN STOCK NOW! Works for 90% of all vehicles!
Retail: $114.95 SALE: $104.95
Why a QUAD? Because despite earlier reports that the downstream sensors don't matter, there have been increasing reports on the forums and in our experience that they do! SO if you have had trouble with your car getting the increase it should be getting, think about upgrading to a digital narrow band quad EFIE and treat those back O2 sensors for the same price as just 2 front ones in the old style efie's.
The Quad Digital EFIE allows much leaner settings on vehicles than other older types of EFIE's which are analog. We are now recommending Digital EFIEs for all narrow band oxygen sensors that are upstream of the catalytic converter. (Note: The Quad EFIE uses a pair of analog EFIEs for the downstream sensors)
Digital EFIEs have the following benefits: Can make the air/fuel mix much leaner than earlier designs. With this device you can lug down your engine, and often kill it if you set it too lean. Absolutely rock steady adjustment no matter what temperature the environment. Will work with older, "tired" oxygen sensors that should have been replaced. One adjustment pot modifies both upstream (Digital) EFIEs equally, and similarly, one pot adjusts both downstream (Analog) EFIEs. This makes these devices easier to set.

NEW WIDE BAND QUAD EFIE- FOR WIDEBAND SENSORS
Retail: $119.95 SALE: $109.95
JUST RELEASED from our manufacturer-, this is an answer to a major problem for some vehicles. Many late model Toyotas, Mazdas, Nissans and others are starting to change over to the Wide Band O2 sensors for more accurate readings, which has been bad for alternative fuel enthusiasts.
The challenge has been that in Wide Band cars, only the front sensors are wideband and the back sensors are alway narrow band. This great new product is the perfect combo of 2 widebands and 2 narrow bands built into one! Just use standard 4 line or 6 line phone cable to hook up to sensors.
The Narrow Band EFIE's do NOT work on variable or wide band O2 sensors. Until now, no other solution has worked, but we have the answer for you now! These are actually easier to adjust than the narrow band EFIE's with only one turn of a screw for both sensors.

BRAND NEW! Digital MAP/MAF ENHANCER FOR MAP/MAF SENSORS
I have not stocked any MAP/MAF sensor enhancers until now, because I am not comfortable with the level of designs sold on ebay (since most of the HHO Generators are junk there). However, our manufacturer just released their brand new version here which blows everyone away! Why? Because the eBay style MAP/MAFs are just simple resistors, which work ok with analog signals, but NOT with the newer frequency modulators. To my knowledge, this is the first combined unit to work with either one AND that does away with the need to switch between Highway or City driving like the cheaper stuff. Also, some MAP/MAFS use a voltage increase, not a decrease. Again- making this unit the only one that handles all situations. It's the one you need if you want to fine tune your MAP/MAF sensors.
Installation/adjustment instructions included with MAP/MAF enhancer upon purchase.
Retail: $99.95 SALE: $89.95
More details from the manufacturer:
Our new frequency based MAP/MAF enhancer is the first universal MAP/MAF Sensor Enhancer. It can be used for devices that output a frequency to the computer, or devices that send an analog voltage signal.
Frequency Type MAP/MAF Sensors
This device works with any standard 5 volt frequency coming from the device, and will attenuate that frequency based on the position of it's controlling potentiometers. It will work with frequency type Ford MAP sensors. It has worked with all frequency type MAFs it has been tested on. It's frequency range is from 30 Hz up to 17 Khz. It has been successfully used on a frequency MAF that operated in the range of 7 Khz to 17 Khz.
Analog MAP/MAF Senosrs
There is also an analog port for use with analog voltage types of MAP or MAF. This is the type of device that are currently controlled with MAP enahancers that you can buy from Ebay. Most analog MAF/MAPs need to have the voltage attenuated in order to lean the air/fuel mix. However, some types of MAP/MAF sensor need to have the voltage increased in order to lean the mix. The Ebay MAP enhancers cannot handle this type of of device. However, ours can. By changing one switch position, this device will change from decreasing the voltage to increasing the voltage.
Note, if you like having a "dual edge" MAP enhancer, where you have to flip the switch to change from city to highway driving, then you won't want to use this board. This device was designed to be set up properly for general use, and then left alone. We don't feel that having to manually change settings while driving is necessary or desirable.
