iDrive to display torque and horsepower in real time?

[Powerslide]

So - is this true? If what I heard is correct (read it somewhere on this forum) that would be AWESOME........

[gee-m-w]

I don't think the computer actually knows that value. But it could relate the RPM to a dyno run and give you an approximation. Heat and atmospheric conditions would trend those numbers down.

I am shocked it took that long, GTRs nav screen is very cool with the displays.

And also - assuming this is true, how would it be calculated? Would it be a "simple" program that would assume that at a given rpm, assuming full throttle is being applied, that a given crankshaft horsepower and torque are being produced? Or - on the other hand - would the system truly be able to state, without making "assumptions," what the true real time horsepower and torque at the crankshaft are at any given moment in time, regardless of conditions?

iDrive has native Sport Displays that show torque and horsepower, and the figures adjust when you add the M Power Kit. I'm sure the figures will be different for the new F8X as well. They look like this:

Standard feature for the F3x, not just the F8x, correct?

[RealStig]

Yes, they have this feature but so does the 335, so it's nothing new.

Correct!

You mean the F30 or E90?

I'm sure he meant F3X.

Neat

That's pretty lame, IMO.

This is pretty bad ass in the Vette ZO6.

It's BMW so the algorithms would be programmed to read low of course

Wow! You should get a Z06! Then you wouldn't be lame.

Cadillacs are lame, IMO. Not sure what else Government Motors makes that compares to a current BMW?

The Z06 may be bad ass but I'd bet the F8X outsells it 10-1. Most people wouldn't want it as a daily driver, but if you got an $100,000 for track car they are pretty sweet.

You must be 18 years old for such a weak response.
Let a man teach you young buck how it works. When you start making personal attacks on someone in a debate, you lose. END OF STORY. You need to explain why I'm lame without actually saying it. You need to back up why you think I'm lame.
Check out Jonas for a much better response.
For Jonas, GM has unfortuantely spanked BMW's 335, and M5 and barely lost to the 328. I'm a totally BMW fanboy with a LIFETIME CCA membership. You need to read your car mags a lot more. I read them ALL, and I keep seeing BMW coming in LAST plast in comparo's.

The point of my post was to show that we get pseudo torque and HP readings, while GM is giving a full on track lap timer WITH a camera all built in. It's like having a GoPro and Solo II and going through the trouble to integrate the two onto the vid. This is suppose to be the most track oriented car for BMW, isn't it? And guys here are all hoping to get a torque and HP readout???
I guess that's kind of cool??

Aren't we supposed to get the ///M laptimer thingy as a standard feature on the F8X?

Oh wow, you slapped him good

[Powaup]

Yea my moms 428i does that if you switch to sport display. You get a tick mark on how high your last rev went. Wish I had some pics to share

Laptime would be pretty awesome if you could overlay video, or even just use the iPhone to shoot video on the track.

tlp has a few vids where he overlays his Solo data onto his GoPro and it's an awesome learning tool.

It's pretty easy to calculate HP based on all the data available. You can make a rough calculation just based on airflow alone. For instance a airflow of 150g/s equals roughly 150kW or 204Hp.

And then you can adjust for intake temperature, atmospheric pressure, boost pressure, fuel injected etc, etc. There has been apps for your phone that, together with an OBD plug and Bluetooth, has done the same for a few years...

I have to assume it is based on an algorithm that would only work on a stock car. Or would it still accurately give HP reading if the ECU is tuned to increase HP over stock, new intake, new exhaust or larger turbos are installed?
