Re: Long Term Fuel Trim
Actually you need to add the STFT and LTFT together. The total shouldn't exceed 10%. They could be -/+ and adding could equal zero which would be perfect.

Should be 0 with plain gas in normal condtions at sea level. The number should go negative at higher altitudes and go positive with ethanol use.
Should be about 3.5 with 10% ethanol in the gas.
