How to deal with stock 1-2 gear rev hang?

[DiddyNotGuilty]

How do you guys deal with fast shifts at stoplights or stop signs without breaking your passenger's necks? I can shift perfectly smooth going from 1-2 at 3k-3.5k rpm but it takes ATLEAST 2 seconds for the revs to drop to 2k rpm to where it shifts smoothly. Kind of embarrassing when I need to go from 0-40 on a busy main street but look like a total tool when an automatic mini van can do exactly what i can do more smoothly without the hassle of working a manual transmission lol. I refuse to tune it to perform how it should out of the factory. I'll replace the transmission oil when i take it in for it's first oil change, but other than that, are there any other ways I can reduce the bucking without replacing anything stock and turning off rev hang? (rev hang was a huge seller...)

Much appreciated for the help.

This car has such minimal rev-hang. My '21 wrx had awful rev-hang and I ended up having it tuned with an accessport to get rid of it.

When you say minimal rev-hang, does that come with no bucking or jerkiness in shifting? Sure, I could just drop the clutch without regard to how smooth the drive feels lol. I'm sure the car would love it too

just give it gas and release clutch at same time; the clutch will bring the engine speed down. i don't even notice the rev hang anymore. takes a lot of practice, but you'll get a quick and smooth 1-2 shift eventually.

Yeah that was my biggest issue with this car. I just add a bit of throttle when releasing the clutch right before the bite point.

I would imagine a tune would be the only way to get rid of it completely, but I may be wrong.

Oh wow, I thought Honda took care of this in the FL5. Is it an issue even when auto rev match is turned on?

They have not. You can eliminate it with a tune. Auto rev match has no impact on rev hang, it adjusts engine speed on downshifts, not upshifts.

I dont even notice rev hang. I've had so many other cars with horrible hang.. So just give the clutch and throttle a little more finesse, you'll figure it out.

Stop dumping the clutch between gears. Pause briefly at the bite point and you'll drop the RPMs.

On older vehicles without rev-hang, you could just time the clutch pedal and give no thought to the bite point, and have a perfectly smooth shift. That's what you're trying to apply to a modern car and it's why you're experiencing jerkiness.

I wouldn't excuse the rev hang as a modern standard. Many if not most modern manual cars don't have rev hang. These are just the ones I have driven that don't have rev hang: Corvette (C7), Veloster N, Miata (ND), M2 (F87), 911/Cayman, Emira, etc.

I do suspect Honda did it purposely because it somehow gets better gas milage and/or emission numbers in testing environment.

I've never understood the rev-hang problems people have. Do people really stare at the tach waiting for it to drop?

Do you have an FL5? Rev hang isn't this tall tale. It's noticeable, annoying af and borderline kills the experience. It's not about staring at the tach, you can feel it. It feels like an ECU delay or the throttle plate not closing fast enough.

I guess we just drive our cars different as it's never bothered me. Properly using the clutch eliminates any jerkiness and I've never had problems with traffic at red lights.

I haven’t really felt jerkiness but at WOT especially shifting before redline I’ve noticed the engine continues to rev up after letting off the gas and putting the clutch in. I think any jerkiness is fixable through driving, also the throttle response/shifting feels a bit better outside of comfort mode.
