I'm wondering if My engine is running at full power

CSanto · 08-31-2012, 11:49 PM

I have reason to believe I'm currently not running at full power. I just hit 40k miles and the car just seems sluggish. I don't ever remember thinking it was this slow.

My question is: is there any way a BMW tech can make sure my engine is running properly. Or should I just go get it dyno'd to see what whp I'm putting down?

I may have the old software but like I said I don't ever remembering thinking to myself this car seems sluggish.

Thanks for the feedback.

An easier way would be to compare the speed of your car to that of another "known good" M3's (on a closed course...). I have done this before since my car can feel very slow sometimes. I think it has something to do with riding the sportbike too much.

Have you had you spark plugs changed already?

Filter could be dirty, lax driving adapts the car to a more sluggish feeling, older software, bad plugs (I'm sure your service 1 just gave you new plugs), or maybe just a bad batch of gas.

The ECU does have an adaptive system in that it recognises when it is being driven in a "fuel saving" (slow) manner and adjusts the ECU map to provide optimum mpg (which also reduces power somewhat). Driving full throttle and high rpm for a period of time will reset the ECU back to full power mode. If you take it into a dealer this is their default method of "repair" for owners who report M3s down on power.

Thank you all very much. Maybe I need to do some spirited driving. I dd my car and often I'm I'm traffic with the tranny in D3.

I'm unsure on the spark plugs. I need to see if they've changed them recently.

No I am not the magazine, I just like the magazine very much and think it's a cool name, so I use it as my username on a few sites
