New M5 Owner - M5 is... Slow?

yea mdm is a must because the dsc is so good at what it does it will make u just think it was a slow pull and not that it just lost traction and it came in..

happened to me last night and I thought it was a bad pull or i hit the gear wrong or whatever and then my passenger said a light was blinking .i lost traction in full dsc mode.. and like I said it didn't even feel like it, it just felt like the car was slow

- if you and your girl dont feel like its pulling like a train, something's up.

but i never get on it out the hole unless in mdm.. its impossible wuth dsc fully on

so put it in MDM, drive 20 miles and get warm tires and if you dont feel the pull of 500 lb ft when u get on it u got a problem

ps: my 550 was stage 2 dinan

That suspension comment is completely true, the softer suspension allows a bit more weight transfer as torque comes in and if there are any small bumps the extra compliance at the rear will mean less chance of a wheel skipping

One other comment, your video is in drive with it starting in 6th then dropping to 3rd. I’ve had a number of times when a gearshift has upset the car. Go for 3rd manual and come onto the throttle at about 2500rpm, with the suspension on comfort and the small bit of lag you get from the turbos the car will settle on the rear axle a bit better and should hook up well

Yeah, 100% sure I was just a noob with the platform.

DSC was my problem. The car felt slow but it was actually just DSC kicking in every time. With DSC off, this thing tears the doors off.

What is the ideal power band for launching or pulls? I found that 4-5k had the strongest punch at WOT.

lower gears, anywhere over 2,500rpm. going 45-50mph ready to pass someone drop it into 2nd and stomp it... with mdm on. it may fishtail and hook.. or just hook . just be ready to shift to 3rd pretty much immeduately

also, you cant floor it and take off if you are not on warm michelin 4s tires and have it in mdm or no dsc at all. if traction control is on, its gonna intrude and kill power.

i drive mine in comfort and s1 auto and s2 manual on the regular and it throws my head into the headrests all the time and i smoke everything that i can coax into running me but most people are afraid of embarrassment.

-not talking crap, but if you had gone the right route and gotten a soul muffler bypass system, they come with surgical grade vacuum plugs and put it in the install pamphlet.
plugging the lines is a crucial and well known and talked about part of getting an aftermarket exhaust on our cars

BUT, i think you have a turbo out bc i went from a dinan tuned f10 550 to the m5 and its not even a comparison and I guarantee you my 550 was faster than any 535

I have the TU 550 and I have to admit, I am still learning my F10 M5. It's definitely impressive, but I too am wandering about the lack of pull in low RPMs. My 550 truly throws me back in comfort mode and is an absolute rocket in sport+. The M just seems to be leaving me wanting more while accelerating, even in sport+. I also look at it like my previous 2 bikes. I had a gsxr and FZ09. Gsxr was all horsepower and better for long pulls, but the FZ09 was all torque and completely insane in Low RPMs. With the 550 being rated 445/480 and the M 575/500... I'm curious if the "lack" of power we are feeling is from the M just having more shine when in mid - high RPMs. I sware my 550 snatches paint off of other cars and I love that thing.

my 550 was stage 2 dinan rated at 500hp 600tq and it was definite improvement over stock.
the 550 was easier to drive bc u just floor it and it went
but the m5's 500tq smokes the tires thru 3rd untuned..
u have to shift out of first very early on a pull
i thought the 550 pulled like a train
but no
the m5 pulls like a train
all its power at 1500rpm
due to that it is actually good to shift 200-500rpm before redline

im convinced somethings wrong with your m5

Had the M fully inspected upon purchase and it came out perfect. I would contribute it to lack of knowledge on the M from myself, not a malfunction of any kind. The M pulls don't get me wrong, but I'm pretty sure the 550 is tuned to have characteristics of more low end pull vs the M5 being tuned for top end. One obvious quality from each regarding this could be seen in the way the 550 is ready to go when letting off the brake vs the M needing pedal input and acting more like a manual tranny. I'm going to take both cars out this weekend and test them out.

Agree,there's too much about having it on the max settings and ripping the tyres to shreds.
I have it in auto,dsc on with mdm in sport and soft suspension and it goes off quicker than all these 'hard' settings.The max settings only work on a race track

hey didnt OP just wreck the m5?

Yes I did. I was able to solve the "slow" issues.

But I did end up dynoing it prior to solving the issues and it in fact was dynoing quite low. It was a combination of old spark plugs, bad gas, and 02 sensors that needed replacing

sucks but very nice u figured out the sluggishness. i got new plugs pronto and i only run pure 93. my o2 sensors are obsolete.

what tune did u run? bpm stage 2?

I ran bootmod3 stage 2. With some E85 blended in each fill up because gas in my city is bad, even 93.

Why are your 02 sensors obsolete?

catless downpipes. u had to have catless dp's running stage 2.. the o2 sensors are of no use.

That's incorrect, there are two sets of 02 sensors. Front set (Pre-cat) and Rear set (post-cat). The Catless downpipes only make the ones in the back obsolete as they are used only for checking emissions.

The front two sensors are very important as they monitor your AFR and help your ECU adjust trims. Those are very important in your car not running lean/rich.

If you don't believe me, unplug your front two 02 sensors and drive your vehicle. One of mine was completely burnt out (left bank) and I was making nearly 60 less HP than I should've been and the car backfired a lot.

I thought I was the only one it happened to... DSC kicks in all the time... At first, I thought that was something wrong with the car

Did you find a new M5 yet?

Was in heavy traffic the other day and as I see the left lane open up, I gradually accelerate from 45 to about 70, (speed limit is 70) and some jerk jumps in front of me. I pull the schumacher move and pass on the right. Eco/comf/com and DSC on at 65-70mph, I mash it and my trac light comes on lol.

"Eventually" it pulls away but damn, I'm only stg 1 and this car loses traction at highway speeds lol monster for sure.

well that would have been why your car was slow as well.

as far as the o2's - yes my back pair are obsolete to be exact. they will be coded out as soon as i tune. im just waiting on cooler weather and less traffic

This is pretty much exactly how I rolled my M5. Except I had TC off and there was transmission fluid on the road and I was trying to get out from behind that vehicle. These vehicles can easily break the wheels lose at 70+ when stage 2.

There are some beautiful ones available right now, but I think I'm going to get a simpler fusion driver + weekend car. It fits my lifestyle better... really really do miss it though.

Will probably get an F90 in a few years when they become a little cheaper.
