Rev Matching jerk

[GrabberBargeCaptain]

If you are on the normal throttle mapping it can be tough to rev match because of the lazy initial throttle response. I know im way smoother with rev matches on sport+ or track mode. Either way its not the cars fault, just need more throttle on normal mode.

The clutch bites real hard on these cars, that's why.

I agree with OP.

I only owned 2 manual cars for about 8 years combined before getting my GT in the fall, but neither had automatic rev matching and i didn't have any trouble shifting smoothly in either direction. My friend has an insane carburetated Cobra kit car that will kill you in the blink of an eye, yet even with my limited seat time in it I naturally shift smoother than in my own bone stock 30k+ mile Mustang.

The clutch and trans combo has been my biggest disappointment with this car, so i just leave the automatic rev matching enabled. And I'm not even a fan of that, either. Neither are horrible, but i just cant seem to get the shifting down nearly as consistently as other vehicles.

Every now and then i disable the automatic rev matching to practice, often for an hour or 2 on on a long trip (especially on local or twisty roads), and i always end up turning the software assist back on.

I won't disagree that it's a "me" problem, but i don't think it's just a "me" problem.

I'm hoping that killing the emissions BS delay through the Ford performance tune will help.

Man I love auto rev match especially in the city. Have to let all the cars hear my 3" straight pipes while coming up to a red light

The only reason for turning the auto rev match off would be if you wanted to rev match yourself. Turning it off and then expecting downshifts to be smooth just like that, without doing anything about it, is a bit foolish. Why do you think they would go through all the trouble to design and build this feature, if the car were able to shift perfectly smoothly without it?
You must keep in mind that this is not an Opel Corsa. This is a 460HP, 550Nm engine, with a strong, hard-biting clutch and tons of engine brake available. You can't expect it to feel and behave like a Golf 1.4 turbo.

Either you learn how to rev match yourself (which I highly recommend, because it's really satisfying when you get the hang of it, and it's a useful skill to have), or you just leave the ARM on, because it really works great and there's absolutely no reason not to like it.

+1 for replacing the factory clutch assist spring.

I've been driving manuals since I learned to drive. Upon taking receipt of Skye, I struggled with smooth engagement of the clutch. The factory setup was very on/off, an all-or-nothing engagement. The Steeda spring and perch kit was a great improvement.

If still on the factory setup, it's definitely something to consider. Others have experimented with and found their own custom spring rates.

It took me a couple months to get used to the gearing, clutch feel and engine resistance for downshifting. For just regular driving around it was just a matter of learning what ground speed or RPM to drop into whatever gear. This is the first car I’ve had with rev matching. I’ve gotten used to using it and I like it. Occasionally I pull it into 4th when I’m wanting 6th and the revs are a nice wake up.

I ordered the Steeda spring after seeing some good reviews here. I’m curious to see how that feels.

I thought this thread was going to be about how much of a jerk I sound like whenever rev match pops the revs to match first as I come up to the stoplight. I mean, I still do it but I know I sound like a tool.

I got first gear rev match tuned off.
Hated going 10mph to lights and it rev matches 2nd to 1st gear.

Yeh it’s not like other cars when downshifting that’s for sure. It’s slow to build up the revs to match the gear without rev matching.

It's important to keep in mind that when you get the rev match wrong on this car you have to bring the rotating mass associated with 8 medium sized pistons and a huge clutch up to speed when you thwack it with the clutch. It'll take a bit more bite out of your momentum than a little 1.8L lawn mower.

What you feel when you downshift without rev matching is engine brake. Because this engine has tons of engine brake, as opposed to those little toys that we're used to in Europe. What passes for "engine braking" in most European cars is a joke by comparison. A Golf can coast for hundreds of yards with the shifter in gear and no throttle. Whereas when a Coyote engine-brakes... well... it does actually brake, it doesn't mess around.
So, when you release the clutch too abruptly, the car wants to slow down hard, because the engine cannot be easily driven by the wheels (whereas small four-pot engines can, to a degree).
