[SonicF90]

Just got my M5 F90 and just finished the break in service. I did Launch Control and I also had the sports display up on the monitor so I can see how much horsepower and torque it was using. I was surprised that in first gear when I launched the car it did not use all of its power (450 hp). In fact, the max horsepower my car used was 560 and that was when I reached 5th gear during my launch.. Is this normal? is 600 horsepower only utilized like in 6th gear or something? you would think that the car would utilize all the power when the gas is pushed down all the way, right? Thoughts anyone?

Perhaps the digital gauges are for entertainment purposes only.

If that was the case you would think that it would still show it using 600 hp tho

What fuel are you using? And the weather matters A LOT. I live in Riyadh Saudi Arabia, and during the afternoon where it’s 30ish degrees Celsius I get around 680 HP, at night I get 720 HP when it’s around 23 degrees celsius.

stage 1 dme, eventuri intake, akrapovic exhaust btw.

Shell 91 Octane. I'm from southern California so the fuel and weather here is pretty good

Try using 93 Octane and hopefully you’ll see a difference.

I posted something similar previously, after the car was sent in for service and to rectify a check engine light, the car now feels slower, and the display also confirms so, only ever reaching 540 hp or so instead of around 600 hp before going into the service center. They did a software update during the service and since then the car feels less powerful more stupid when slowing down and dropping gears by it self. I can be coming to slow down from 100kph to about 40 to take a turn or for a speed bump but it would remain in a high gear and now go down to a lower gear suited to that speed. Previously before the service the car was smart, now its just odd

Good to know it's not just me, yeah the car struggles to hit 540 and it made me wonder why it's not putting down 600 Hp when I got my foot all the way down on the gas and hitting around 7,000 RPM in first gear

Just FYI you aren’t supposed to use LC until after 3100 miles. The manual seemed pretty serious about that.

My manual said 1,200

From M5 owners manual- see pics. So if break-in period is up to 3,100 miles, you shouldn't use LC before then.

Regardless it's not like the full power is not unlocked until I hit 3,100 miles

Maybe BMW is slowly working towards speed limiting its cars like Volvo j/k

[kdeleon]

For launch control, what some people are talking about is from a technical guide that says not to use it before 3,100 miles.

I hacked my Sports Display, not it always reads "11."

It's the the CA 91 octane fuel. This car needs 93 to achieve full spark and boost.
