Hi Everyone

I have the 1.5L turbo with cvt. I used to be able to drive below 110km/hr and still be below 2000rpm. Now I noticed it revs higher for same input on accelerator by 300 revs or so while in D. I noticed this after putting the car in s mode and driving it to 5000 rpm to get up to highway speeds. I normally avoid going over 2000 rpm always. (Generous on the accelator this time as someone told me the turbo needs to be engaged more so it doesn't deteriorate?)

Anyways I was thinking that the ecu can learn how you drive and thus adjust the gear ratios? Hoping it's just maybe a ecu reset? Let me know what you guys think!

S mode in the CVT keeps the transmission on a closer ratio therefore allowing for high engine RPM speed. Higher engine speed results in closer to peak torque RPM ranges. More "get up and go" the ecu could be adjusting fuel map or throttle inputs based on driving for maximum efficiency or engine cooling on the cylinders for Direct injection. unless it's constantly up at high RPM I wouldn't worry too much. This didn't happen to occur shortly after a cold start?

If the engine has to work harder because you have some "drag", the revs will be higher at the same speeds. The CVT is programmed to choose the right RPMs for the situation. Speed, how hard you push on the gas pedal and drag will determine the RPMs. Remember the old style automatics would "gear down and rev higher" on a hill ? A CVT is similar.

For example, if your tires are under-inflated, your brakes are dragging, your rims are warped, your alignment is out, your windows are open are all things that could make the engine work harder. Even the direction of the wind or an uphill grade can change your RPMs at a given speed.

Your car may need some servicing. Or not.

temp seemed to be at operating temperature when it started happening but I drove all winter even in -25 degrees and now it's getting to 10 degrees and I am expecting better fuel economy. I think it's the ecu adjusting as mentioned. Regarding turbo engines is it true to once in awhile engage the turbo to avoid it degrading?

Were you driving into the wind by any chance?
Lmao no I looked at the numbers over a week. It' snot a big deal it was .5L/100km drop. I asked more so to understand how the ecu can be learn our driving habits and if that reflects in your fuel consumption
