'97 Dodge Caravan, Electronic Fuel Injection Enhancer

Q: I recently bought an EFIE (Electronic Fuel Injection Enhancer)from Eagle-Research. The EFIE allows you to apply an offset to the voltage coming from the oxygen sensor, so your vehicle's computer is completely unaware that the oxygen content of the exhaust has increased. See their website: However my local mechanic does not know how to wire it into the computer of my '97 Dodge Caravan 3.0L Van. Can you help?

A: I did a little checking on the gizmo you want to install on your vehicle. First, if your mechanic installs the device he/she could be breaking state and federal law! Why? No where could I find that the product had Federal or California emissions certification. A mechanic or technician installing such a device is lining himself/herself up for a fine that starts in the area of 25g's. All it is going to take is one government type with a hot pepper in the wrong place to make an example of such person. Altering the oxygen sensor value is no big deal and has been used as a diagnostic tool for many years. As for altering the sensor value to improve gas mileage I wouldn't bet much on it. If the company has such a good product why have they not submitted it for testing? Oh they make great claims, but if their product worked so well they would be rich, retired and not wasting any time with a darn website! Why? Any one of a dozen vehicle manufacturers would have bought them out and mass produced and installed said such product on their vehicles. Until I see dyno and emission testing information in grams per-mile, don't ask to sell or install such a device . Also I found the websites reference on how to "Reverse your Electric Meter, Legally" and the 72 hour Disaster Survival Kit with Step-by-step instructions for becoming crisis ready about as useful as a can of instant water.
