efie for 2003 4runner

by stan

I just installed an hho system on my 2003 4runner 4.7 l. engine. the instractions says that I do not need an EFIE, or anything else, and that I can reset the O2 sensor by following certain direction.

disconect battery, key on key off press brackes and etc.
is it really true that O2 sensor memory can be cleaned, or I just need to get EFIE and be done with it
