Is an EFIE important to have with my booster?

[pj91gsx]

I was reading and came across the EFIE and was wondering it my car would be hurting without it or it I need it or if it does or does not matter if I have it or not.

The definition EFEI is used way too broadly. EFEI really is a term used to describe a vehicle as having fuel injection. If you want maximum gain you will have to use something to stop your ECM from offsetting the HHO with more fuel. Your vehicle could have either a normal O2 sensor or a Wideband air/fuel sensor. They both measure oxygen in your exhaust defore the cat. The problem is thet with an O2 sensor the higher the voltage from the sensor the leaner your ECM will make your car run and with an A/F sensor the lower the voltage from your sensor the leaner your car will run. They take very different mod's. The A/F sensor is an easier fix. You simply need a proper rated pentiometer in line between the sensor and the ECM. With the O2 you must add voltage. There is also a MAP or a MAF sensor in your intake that senses the volume of air your engine is using and adjust the fuel injectors accorgingly. The same type of mod as with the A/F sensor should work there. First before begining some research must be done as to how your vehicle is equipped.

As in research you mean? i have one o2 sensor, and a MAF of course, I dont think I have a MAP. So with the EFIE would the motor run slower or would it run faster?

the idea behind the EFIE is to tell the computer to use less gas by adjusting the voltage from the O2 sensor, but not to lean the fuel out to much as too over heat the motor - u can usually tell by engine temp.

Its not that the motor run slower or faster - just more fuel efficient.

well since it would run more rich that might cause the gas to wash down the cylinders? Or is it not enough of a difference?

its not enough to make a diff, but wouldnt u like to get more mpg?

right now with mine, i only see a 1 mpg increase, but since it runs richer, i have a huge horse power increase. :cool:

But you dont know the power difference from having it or not, do you? Im already getting 30+ without the booster, I just want to keep my power as well. I would think it would keep the same power or increase power with or without the EFIE.

u will keep the same power or more.

just because u install a EFIE or MAP EN,doesnt mean ull loose power.

hydrogen makes has more energy than gas = more power. Just do over lean it out and u will have the same or more power.

Are you saying it is a tool that I can use to control the amount of fuel going in? I do have an lc1 innovate wideband but I was not planning to use it on my bmw.

thats exactly what hes saying. since hydroxy is highly flammable, it burns quicker and cleaner than gas. its like adding nitrous oxide. it increases the octane and makes it burn quicker and cleaner. since ur introducing a very flammable material to ur gas, why do u need to use more fuel? (since it detects more oxygen) thats the entire logic behind this device. it uses less gasoline and more air (leaner mixture)

Is this tool hard to use or easy to use? And what do I want to look for for my afr 14.7:1?

is there any easy schematics for building a efie?

all i can say is to look on Google, i havnt found one on here, im looking too.

Again the definition EFIE is very widely used. Building one to help a MAP sensor, A MAF sensor or a wide band Air/Fuel sensor is very easy. Do not buy one of the 30 to 100 dollar products offered on Ebay. All the afore mentioned sensors send a higher voltage signal when they want more fuel to go to the engine. All you have to do is buy a 40 or 50k ohm pentiometer from your local Radio Shack. They are under $2.00. You splice it into the sensor wire and adjust the voltage down to where you want it. BE CAREFUL TOO LEAN A AIR FUEL RATIO WILL BURN HOLES IN YOUR PISTON. Start slowly and monitor cylinder head temp's. Do not let the temp go more than 50 degrees above what it normally runs.

so how close are the MAP and O2 sensor enhancers in wiring??

this is off a diff post but has a schematic


They call it a mixture controller.
all the parts were pretty easy to find

sounds good I look into the cheaper way first.

so, does anyone have the radio shack resistors working or should I just get the efie?

I got an Efie from Fuel-saver.org. If I'd know it was going to work that easy I would have done it 2 months ago. Every time I turned the gen on my mpg's went down. Just got efie hooked up and first test mpg went up 6mpg.

cool. im getting one this weekend. I dont know where yet. one guy sells them for 25 on ebay, he makes them and gives a 2 year warrenty on them.
