The "Original E.F.I.E. U Solder Kit " George Wiseman from Eagle Research coined the name " Electronic Fuel Injection Enhancer" EFIE circuit that is easy to install, should take just one or 2 hours for an experienced mechanic or car stereo installer. Longer time, for the laymen. The EFIE allows you to customize and 'correct' the voltage signal coming from your oxygen sensor; so that your computer doesn't know there is extra oxygen in the exhaust. Can also be purchased all soldered and tested as well, for those who do not solder or have the time. More installation and operating instructions are here.

The EFIE allows you to retain all your power and performance while taking advantage of increased mileage. No matter what fuel saver device or method you use on your fuel injected vehicle, you'll need the EFIE to unleash the full potential of the fuel saver. Works well with OBD I cars and trucks ( 1987 - 1995) and also on OBD II vehicles ( 1996 - 2014)

The EFIE alone can save 5% - 10% on your fuel bill, simply by 'leaning' your fuel mixture. We do not consider the EFIE to be a fuel saver on it's own. The EFIE is designed to be an ASSIST for fuel savers. We do not consider any technology to be a practical fuel saver unless it can save at least 25% on at least 75% of vehicles!

This EFIE has been working for 20 years! THis EFIE replaces teh 18/1 EFIE we used to sell. Sorry The DEFIE is no longer available. The designer is no longer making them.

We ship 5 days a week, only $6.10 for USPS Priority mail. 90% of the time we ship the next day after you order.

Your O2 sensor is really a fume sniffer, it does not sense oxygen at all?  Go read about it.
