CVT's (non-hybrid) = fewer opportunities for fuel-cut mode (DFCO) when coasting?

[cRiPpLe_rOoStEr]

These are fitted with a CVT, and non-hybrid.




I drove a sedan a couple of times in 2020, not a taxi though, but I didn't notice much chance for DFCO, as the CVT tends to keep a constant RPM which may vary according to how lead-footed is (or isn't) the driver.

My Ultra Gauge sometimes on downhill coasts will give me readings of 175-200 MPG but even then it's constantly changing with speed and rpm. The only possible indication is in the factory installed MPG unit. It will go to 99.9 but the Ultra Gauge is just showing that it has exceeded its limits. The Scan Gauge in my Ford Escort wagon with 5 speed manual will go to 9999 as soon as I let off the gas at highway speed and stay there until either I accelerate again or the engine needs fuel to continue to operate.

With problems that have plagued the CVT I refuse to shift from "D" to "N" and back to "D" to save a couple drops of gas. If it did cause any problems with the CVT it certainly wouldn't be worth the $4000-$5000. they want to replace one.

it's been a few years since I last replied

the issue is the transmission pump isn't running in neutral, this means you will wear out some stuff in the transmission
unless you get an eAUX pump or something

i got a AUX pump it's always running when in neutral gear, reverse and auto stop... i get 2mpg more with using the neutral gear DFCO is sloppy
neutral gear rpm drops to 600RPM and the drive train free to go as it pleases (SUV has a lot of mass)
