civic ECU chip

my original intent was NOT to make you lok like an idiot BUT just to validate that you don't know what you are talking about i instant messaged you, as did my friend who is a mechanic and to be honest you are a baffoon, you said you are a "machanic" (mechanic is proper spelling) and you give out horrible inaccurate information. You cannot use the stock O2 sensor because it is not a wideband sensor and will not give you an accurate representation of precise A/F ratio. Then in IM to my friend Paxtonpwr who is a real tuner, when he asked you what your A/F was you said it was on"paper" and he said 10:1, 9:1 as a joke and you told him that would blow up the motor and was too lean. Well anyone who has a clue knows that 10:1 or lower would be very RICH , because 14.7 is stoichiometric A/F = ( atmosphere is 14.7:1) and represents a complete combustion process but that would be much too lean in production automobiles so most cars operate best naturally aspirated around 13:1 or so, poweradder cars will usually be a little lower 12.5:1 or so for safety You are another wannabe tuner with no experience you changed oil at a nissan dealership (and was fired) and think you are master mechanic, you have no knowledge and could cause people to damage their motors. you should really refrain from giving out information that is inacurate, OR that you are not %100 sure of.
