Mode and tuning question
As all non F-Sport drivers may know, our gen 3s have 3 driving modes…Eco (economy), Normal (off), and Sport.
The shifting in these modes is self explanatory…Eco has very low RPM shift points, and is a bit lazy, Normal is regular, and Sport has high RPM shift points, and is aggressive.
Now I have a few questions…
1. In Eco mode, it seems to lag the engine quite a bit by staying in a higher gear when accelerating…is this healthy for my engine?
2. Are these modes different shifting tunes only, or are there engine tunes that are loaded too?
3. And if Yes to #2, if I get an aftermarket tune, will it only load in Sport mode, or is that tune “across the board”?
Looking for some real answers, not guesses and speculation, hell, I can do that…I’m the biggest speculator on the planet, lol!
Thanks!

1. No issues there. But depending on your driving, you might actually get less MPG in Eco mode. I never use it.
2. Sport mode will get the tranny to shift higher and hold gears a bit longer, the steering wil be a bit more heavy and the gas pedal will be more responsive. But all that is not really tunes per say, just different parameters in the ECU.
3. Actual "real tunes" like the RR Racing one will actually change lots more that just pedal responsiveness and shift points, they actually alter the fuel and ignition maps in the ECU to make them more performant (something driving modes don't do).

Answer to your first question, I would assume it's better for the engine since it's forcing the car to shift at lower RPM, causing the car to stay in the highest gear which has the least amount of stress on your engine. I mostly use eco in parking lots, 25-35mph speed zones, bumper to bumper traffic. Highway driving normal, if in a rush Sport or even manual mode.
People say Eco mode doesn't work but I'd beg to differ since the car is always trying to stay in the 6th gear (or 8 if you have the 8 speed). That is the biggest factor in fuel savings versus having to put your foot on the gas. In Sport mode, obviously the worst. Normal + manual mode, putting it into the highest gear, I would assume be the best though
