At partial throttle timing between paddle input and actual shifting was almost instant but at WOT there seems to be a bit of a delay.

Anyone else notice this?

Yes. This guy got rid of his car because of it.

built in torque pull/tcu delay to save the longevity of the transmission would be my guess once the throttle position is past a certain threshold or the kickdown switch.

may be resolved in the CSL from evidence of the quicker shifts on the 'ring laps we've seen but like i've theorized in the past... that TCU tuning won't see the light of day in normal production cars and maybe not even in the G80 M3 CS.

I could definitely see that during the shift but not response time from paddle to Tranny.

This is a torque converter automatic afterall... not a DCT. Shifts won't be as snappy after pulling the paddle. But as a torque converter it's one of the best.

+1 more for the 6MT

I don't think you guys are understanding me. I don't mind the actual shift action and I've owned many cars with DCT/PDK.

What I find odd is that it feels like a full second between the time of pulling the paddle and the transmission actually starting to shift, but only at WOT. But at somewhat aggressive partial throttle, as soon as I pull the paddle it shifts.

Next time I'm going to try without pushing the gas pedal past kickdown.

Yes, I agree. Not the actual transmission, but seems like a delay in the communication between the paddles and the transmission.

Did you read through that thread I posted? The OP of that thread goes into a lot of detail.

Yes it's much slower than the f90 shifts. It almost feels faster in comfort. When xhp comes out with a flash I'm sure it'll be better.

When you say delay in a shift at WOT, do you mean only a delay at WOT when you're at redline, or do you mean WOT in general? Meaning even during short shifts?

I've mentioned the same exact thing a few times on the forum. I know there is a couple others who experience the same issue.

I have a manual, but this would surely bother me. Hope you get this resolved if it can be.

Last night I read the 6 page thread by AndroidRobot. I thought if the shifting is such a concern, why not go manual? Flipping paddles is nothing like shifting your own gears. I have never driven a DCT, they sound awesome. But every buyer of the G80/82 knows these cars don't have that transmission. So it won't shift like a car that does, and even those are nothing like a manual.

I am not even one month old with my 6MT Blackwing, and I am starting to question whether the M4 Comp xD I ordered is worth adding. I love the look inside and out, I wanted AWD, but I am realizing it is going to be very bland by comparison.

In my case, because the G83 is only offered in comp/awd/auto. Otherwise, I would have gone with a manual

Same dilemma for me - I wanted the AWD. Automatic only. But I could care less how quick the paddles shift the transmission.

How long have you owned the car? How many miles?

Have you owned a ZF-based BMW producing ~300 Hp or higher prior to this?

Yes I've driven and owned several ZF cars.

So one thing Ive noticed this morning is that comm between paddle input and shift is quicker in higher gears but 1-2 and 2-3 there is a bit of lag. Maybe it revs so fast due that I notice the delay more in shorter gears.

[Purekoryo]

Drove some more today and it's pretty random between delay no delay. TCU must have some weird logic for sure. I remember my old 911 with PDK was like this but not as random and more consistent once warmed up.

I'm also thinking it's in my head because when I pay attention to the shift lights rather than the rev, the perception is less delay.

It's not something you can fix without maybe an aftermarket tune. Yes I did sell my car mainly because of that. The ZF8 will never perform like a DCT so since I wanted a more engaging experience I opted for my current car.

If you find a way to fix it, which I hope you do, please share it with the rest of us.

I tried to play with the paddles today and i did not notice any type of delay comparing to other ZF equipped cars i've driven like hellcats and scatpacks mainly. I can't compare it to a PDK which i assume is the fastest shifting there is on the market. But i did live with a friends GTR for 4 months and i can say this is on par with the responsiveness. Although he had an older model so i'm not sure if they improved this throughout the newer years.

Yeah I suspect the CS/CSL will have better tune. If not, I'm sure there will be an aftermarket TCU tune in 1-2 years.

Although I came from a quick shifting 911 GTS PDK, at partial throttle G80 M3 does a good job and don't mind the slight delay one bit. It's when I go WOT that bothers me. But probably not enough to sell the car.

WOT while short-shifting at around 5K rpm seems quick enough but >6K can pm not so much.
