Does tht include hardware to laod it?
Of course, tuners always list the 93 tune, itās better marketing. Fine with me, I only run 93 anyways. Always have and will on FI engines.
Interesting, I never knew that. Haven't spent any time out West, unfortunately. I get out there eventually.
This is my first turbo engine and I'm trying to run 93 but it's 90 cents more a gallon than regular right now where I live! Hard to justify it every fill up. Does switching back and forth mess with the computer learning?
I have no idea, honestly. Before going back to Ford, I had two different BMWs (135i and X3 35i) that both required premium. When I got my '15 Fusion new in 2015, I ran one tank of regular, then tried 93. The car ran SO much better, so I only ever ran 93 after that. My ranger has seen 93 since day one.
Look for a Costco nearby. Itās usually .60c a gallon cheaper than any other place on premium. I get 91 for less than others places charge for 87. As for switching back and forth, it wonāt hurt anything. The ECU is able to adapt without issue just donāt expect the same power on lower octane.
Around 25 years ago we used to have 92 but that went away like common sense in this state.
It takes a week or two for the OAR (Octane Adjustment Reading), to compensate when you switch. It just may not take advantage when you switch to the higher unless is for a few tanks.
I wouldnāt go as far to say it takes weeks but it is an active learning process that adjusts instantly to the fuel you use to gather a cumulative rating of effective octane. The ideal -1.0 multiplier is achieved if the fuel is of higher octane than the required minimum. It starts out at 0.0 and the learned octane multiplier can go from +1.0 to -1.0, being a multiplier the -1.0 is our target. All of the data collected over time... is used to calculate and adjust this learned octane value.
