Two explanations are given for what to do if your vehicle uses frequency instead of voltage. One requires a MAP/MAF Enahancer and the other a EFI Enhancer. Why?
There are different schools of thought.
The overall goal is to
"trick" the on board computer into reducing the fuel usage because not
as much fuel is needed due to the influx of oxygen and hydrogen gas.
Some people have obtained the best results by using the ground wire
with a resistor when the vehicle uses frequency instead of voltage.
Others
have recommended to use a EFIE or in the case that there are 2 oxygen
sensors, use a dual EFIE (not 2 EFIEs). We also include plans to build
an EFIE.
The cheapest solution is the wrapping of oxygen sensors with aluminum foil.
The
recommendation we have as well as our builders is to start with the
easiest and cheapest solutions first. In many cases, they do the trick
and you get the improved gas efficiency you desire. Other times, an
EFIE (or dual) is needed.
