So there is a special trick dyno testers have to do with the latest M3's computer to get it to redline while dynoying. In this above cases, none of the latest gen. M3s were tested to redline....but it give us a good estimation of what happens up to about 6K rpm.

gavriil

Unbelievable how torquey the previous gen. M3's engine was (USA Spec).

Crazy Bimmer

if anyone cares, my 330 dynoed at 197hp and 201lbs of torque stock

Just to compare.

gavriil

Here is the trick.
-----------------------------------

How to get around the 6500rpm limiter issue in an 03 E46 M3 SMG:

Some people talk about pushing DSC for 10 seconds -- I tried this to no avail. All that happened was my dash lit up like a Christmas tree but I still couldn't get past 6500rpms.

I know some people talked about fuse 34 -- I never tried that. I just tried the various "hold DSC for x seconds" trick and it never worked for me.

The Solution:

Before you turn the car on pull fuses 33, 56, and 61, which can be found in the glove compartment.

Now begin your dyno run. Your car instrument panel will light up like a Christmas tree (i.e. ABS light, etc etc). However, you can now dyno to redline! Once the dyno run is completed, put the fuses back in. All the lights will shut off once you start driving.

gavriil

And it's a 2003?

gavriil

So that's about 229HP at the crank, at 16% drivetrain loss. BMWs are always underrated from the factory. It's been proven many times.

GreenMonster

Got to love a motor that puts out more peak tq then hp.

Crazy Bimmer

my 330 was a 2002 5-speed

Type S

thanks for sharing these precious info and date
E36 M3 is always my dream car..
although E46 is already avaliable on the market

gavriil

No problem.

wtf? 272 trq-282trq at the FLYWHEEL? BMW underrating the engine a tad??

zeroday

don't you mean overrating? I thought an 01-03 m3 made 330 at the crank?

gavriil

Zero, please look at my comment about redlining a current M3 while dynoing.

Crazy Bimmer

doesnt the 01-03 M3 have a high reving engine and thats how it gets the power? Well if they didnt redline the car then that means all the power wasnt layed down, rite?

zeroday

yeah but dynos should be looking at real world performance...not what the engine would do if you pulled fuses etc?? If the ecu RESTRICTS rpm's then that's how the car should be tested. Shit if I gutted my Z's interior and removed my rear hatch i'd be in the low 13's...

Zapata

TRQ not HP...... i'm talkin TRQ is 262 at the FLYWHEEL

gavriil

So what we know from the above is that a current generation M3 makes about 307 @ 6352 rpm at the crank. BMW claims peak HP of 333HP at 7900 rpm. Totally doable and I can even say it's underrated from the factory. Would not be surprised to see 350HP at the crank from a stock M3.

Zapata

:ghey:



ECU needs to pulled because the TCS and DSC kick off to the best of my understanding....

zeroday

"CAPABLE" is alot different than what the car is tuned for. just pointing that out.

zeroday

care to elaborate?

Zapata

not sure what you mean buy capability....m3 will run low 13's all day. Pulling the ECU is only so you can dyno it....it's not unleashing any additional power.

somebody with a bmw will elaborate.....

zeroday

my car and the CLS both have a button for this...you're saying the M3 doesn't?

zeroday

this is where i'm unclear. why again do you have to pull the ecu to dyno the car? from gav's posts it looked like it was to rev past the stock limiter.

Zapata

nah it does but the ECU overides it or something....

gavriil

Wait a minute. You make it sound that if I pulled fuses to fool the ECU to let me redline the car while dynoying, I am cheating. Is that what you're implying? If yes, I disagree.

zeroday

That was a question Gavrill...if that's not why you have to pull fuses to dyno the car, please explain again to me. I am thick sometimes lol.

gavriil

They dont "pull the ECU". They pull 3 fuses to fool the ECU so it lets the engine redline.

I am not clear of why the ECU wont let them redline the engine in the first place, but I dont doubt it does. As you see from the several dynos, no car could go near the redline

zeroday

yeah the car wouldn't run very well without an ecu would it lol. so if I owned an m3, why would i not pull these fuses out permanently....this needs more research...

zeroday

I still think if you're comparing stock/stock dynos however the car needs to be as it comes from the factory; fuses and all.

gavriil

Zero, they are not pulling fuses to cheat. They are pulling fuses so that they make the ECU LET THEM reach redline. No extra power comes from them pulling fuses. Clear now?

zeroday

far from clear. why would you want to reach redline if no more power is unleashed by reaching it? collect underwear>?>profit...

zeroday

all i'm saying is a car should be dynoed as stock in it's 'stock' configuration...without pulling fuses. Not doubting the car can dyno what you guys are saying if you yanks a fuse or two.

gavriil

So I will pretend you dont know anything about the current M3 (which is probably untrue).

The answer to the above is:

Because the M3's engine makes A LOT MORE power above the 6K rpm area that the ECU lets these folks reach while dynoying.

Is that clearer now?

zeroday

Yes. But I do wonder what you lose by pulling the fuses. Why not leave them out permanently if it produces...sorry...unleashes....such gains?

zeroday

btw 'stock' to me means how a car comes form the factory; unmodified. If I see a stock vs stock dyno where one of the cars is an m3 I expect no one will be pulling fuses.

gavriil

The gains dont come from pulling the fuses! The gains come from letting the engine go above 6K rpm where a lot more power is made. As I wrote the M3 makes 333 HP at 7900 rpm according to BMW. If you stop at anything below 7900 rpm, you will see a lower HP result. That's how the engine is tuned.

gavriil

The M3 wont let you reach redline ONLY WHEN YOU TRY TO DYNO IT in this case! Clearer now?

Crazy Bimmer

damn it here. I went searching and this is what i found.

Its a traction problem when you are dynoing. Since the rear wheels are moving that much faster than the front wheels, which are stopped, it cuts it at 6500 rpm.

Heres what else i found....

If this is a man trans car...

1) Tie down to dyno and make all hook-ups
2) Start car and turn "off" DSC (lighted)
3) Turn off Dyno brake and run to 6200 rpm... do not exceed 6500 and do not go lower than 6000.
4) Clutch the car and hit the dyno brake.
5) Once wheels have stopped turn car off to key pos 1 (do not turn off all the way or you are hosed)
6) Turn key to pos 2 (dash lights)
7) Press and hold DSC button for 10 - 12 sec. and release
8) Start car and run happily to 8k...

If for some reason you miss a step the car will not go passed the 6.5k mark. All of your lights will be lit. i.e. DSC, Brake, ABS, Blow-out, etc... you will have to take the car off of the dyno and drive over 15mph to reset all of the lights.

Crazy Bimmer
