Fire Spark

I'm not really up on modern vehicle ecu performance upgrades. Sometimes It feels like the drive-by-wire is holding back the revs I'm trying to give it and I would like to eliminate that sluggishness and inconsistency in the power delivery.

None so far with my 2017. Mostly used in stop/go town driving so a lot of clutching and shifting. 41 MPG.
 
I've always given the door hinge pins/bushings on my vehicles a shot of lube a couple times a year to keep them from squeaking/wearing. 70's cars were famous for getting saggy doors that you would have to lift up to latch because the hinge pins/bushings would wear if you didn't keep them lubed and it would throw those long heavy doors out of alignment.

He probably just changes the filter and adds a little oil to compensate for what the filter held and what runs out of the galleries. Most of the oil stays in the pan.

That's really cool.  
 

Do you notice any more power?

As far as I know the only changes to the 2019 LS were purely cosmetic (wheel covers, color choices, chrome grill trim, fog light covers). Everything you mentioned should work on 2016-present.

That idle sounds much smoother than your earlier video!

Make sure to give us video when you roll out in this hot hatch. 

Looks great. I love those little mag wheels.

Sounds like his clutch is toast. Bobby, all automatics including CVT's have clutch plates and/or friction bands that can and do wear out eventually and are much more expensive and labor intensive to replace than a manual clutch would be. You might be thinking of the torque converter that is between the engine and transmission which kind of does the job of a manual clutch when idling, coasting, and accelerating smoothly from a dead stop. Those rarely give problems because like you said they are just a fluid coupler without any wear points besides the bearings. The clutch in a lock up torque converter can wear out however. 

Congrats. These cars grow on you. I bought mine as a cheap point A to B car also but have discovered it is actually quite zippy and quick handling if you're not afraid to rev it up through the gears a bit. The new Fit looks like a mini-minivan to me and the interior is noisier and more plasticky than the Spark. I do like the magic seats though, wish the Spark seats folded completely down flat like that but then again with a tiny car you have to make some sacrifices. The HRV is nicely styled but is powered by the last generation Civic engine to cut cost so power is lackluster. It is in desperate need of a larger engine or turbo to move a heavier and less aerodynamic vehicle than the Civic.
