Hey guys, been spending a few days with the M2 as I think I'm going to buy one. Wondering if this is an issue with just the M2 I'm driving or the DCT in all M2s... when you shift into reverse and hit the throttle, there's a huge lag before it actually revs up and moves. Same if you're in reverse and switch to 1st, you have to wait like a full second before pressing the throttle or it just doesn't register/rev/go anywhere.

Is this delay normal? Pretty annoying actually, especially if making a 3-point turn.

Normal. Usually on start up.

Why? What's behind that? Not an issue on any other car I've driven as far as I can recall.

Reverse takes a bit to switch over to. For me, it happens when I go from park to drive it takes a bit to switch over and there's a bit of lag and it jumps. For three point turns it's usually not an issue, but sometimes it can be.

Std DCT, you can speed it up with the GTS DCT performance flash

I have a fix for that.

Get the manual.

And if he gets it in 'Hockenheim Silver Metallic', it will be a metaphoric "silver bullet".

What is that and how does one do it?

A full second? Who has that kind of time?

Yea that's on mine MY17. It doesn't seem like it's always laggy but I take care to try not to jam on the gas as soon as I put it into reverse. It's only really annoying if someone is waiting on you. I don't recall it feeling as laggy when I been driving for a while, or maybe that's just because it's in sport/sport+/traction mode and not comfort at the end of a drive. When I just fire it up to move the car I don't bother getting it out of comfort. The other modes have faster crisper shifts and comfort has laggy shifts so, try that I guess.

I have actually mashed the gas too hard in reverse because it was laggy and then it spins the tires lol. Maybe I drank the koolaid but I consider it a charming character of the DCT.

I dunno I feel like either way it probably won't make or break your decision on the M2.

Yeah, that's another thing: the M2 should start in Sport mode by default! Who the hell drives an M2 in Comfort? You should be required to press and HOLD to confirm you want Comfort.

Well it does warm up faster in Comfort because it doesn't run the intercooler as aggressively, so there is that. In theory this is also true in traction-MDM mode (quick press the traction button) which gets you faster shifts, more sound if you're picking the gears yourself, and traction control partially off.

I typically wait to move the car over to Sport+ until the car is warm.

I have the same issue with my 2018, but most mornings since I took delivery it's been below 20 degrees. It's much better once the transmission warms up after a few minutes of driving.

The intercooler is air to air there is no mechanism to control how effective it is at cooling maybe you mean the coolant system?

Anyway I see this comfort thing asked a lot. The reason behind it is emissions. That's why the throttle pedal is so dull as well. Comfort mode is engineered to optimize the EPA drive cycle for emissions and fuel economy testing so they can put a nice number on the sticker / also not harm their CAFE quota. (CAFE is US fleet gas economy standards, manufacturers have to reach a certain level of fuel efficiency). Anyway in order for them to be able to use this mode as the testing mode the car has to default to it on Startup. That's why we can't have the car to start in sport. Pretty sure the same thing applies in Europe.

That was my immediate thought when I read this thread title...

Thanks clarifying that. When akkando mentioned that, it didn't sound right to me from what I know about turbocharged cars I've had. I don't know that much about the M2 so I wasn't sure if there was something I wasn't aware of.

No I'm just dumb.

Not sure if the DCT is like VAG DSG, but if so...
They put 1 and R on different gearshafts, so that should help with shift speed. However, if you're in 1 and moving, the car is going to want to preselect 2. If you then put it in reverse, it has to get out of 2, and then grab R before it can engage the clutch and get you moving.

It's just one of the unfortunate disadvantages of the predictive logic and engineering choice of where to put R on a dual-clutch gearbox.

You have pretty much said what I wanted to say.

As for M4GTS flash, I wasn’t aware we can do that for the M2. Has anyone actually tried this?

By every measure, an inferior product.

Oh it might be but it will still fix the problem.
