Question about 1995 Toyota Camry
Reset emc to burn premium
ECM. And no it does not. the fuel "table" is a timing calibration based on mechanical conditions, primarily valve timing and mechanical compression ratio. Simply reprogramming software doesnt change cam profiles or compression ratio and youd be doing more harm than good. The good news is most modern cars are smart enough to know if they are "pinging" or "knocking" from too low an octane fuel and make adjustments automatically. Go ahead and try going down 1 grade and if you dont hear noise by the 2nd tankful, you will be fine. Some engines are high compression or dont have sensors for detonation (knock sensors) and you wont get a change and must simply run the better fuels, but at worst, you finish a tank or 2 and switch back if the noises never gi away.
