oddlycalm Member Posts: 30 Registered: Apr 2002	posted 05-07-2002 09:39 PM Thanks for posting the DME dump bbj. Well, we now have confirmation that either the DME's are flawed, or the rev limiter or SMG are. How do you get to 8460Rpm for one minute total with an SMG and functioning rev limiter??? My guess is that you never did. oc IP: Logged

MattsMthree Member Posts: 24 Registered: Jan 2002	posted 05-08-2002 01:13 AM When exactly is the rev-limiter suppossed to kick in? Does anyone know if it is a spark-interupt limiter or is it fuel+spark? I imagine that it might be possible to rev a motor a little bit beyond the limiter due to flywheel inertia/ so-called "soft" limiters, and any other factor that I am unaware of. Granted, I'm only talking about a hundred revs or so. As far as SMG is concerned, it's just as easy to hit the rev-limiter (on acceleration) as the 6 spd, and if in sequential mode, it will bang off it all day long. I hate to think that there are big problems with M3 bottom ends, but there seems to be alot of evidence supporting that fact. I know I broke mine in very carefully. Now (And forever actually...)I won't run it over 4,000 rpms until the oil is at full operating temp (Especially with 10W-60!!). Anyway, sorry to hear about your troubles, and best of luck. Keep us posted... Best regards, Matt IP: Logged

My guess is that you never did. oc That "1/min" stands for RPM-revolutions per minute. The over-rev duration is 13.184s but that doesn't mean it was at the n_max 8460 but anything over 7800 (according to conforti) http://forums.roadfly.org/bmw/forums/e46m3/forum.php?postid=411188&page=10 http://members.roadfly.com/jason/m3engines.htm IP: Logged

Speedi Member Posts: 339 Registered: Jan 2002	posted 05-08-2002 07:28 AM What about the SMG-Adaptation checkbox? If this was an SMG, shouldn't this box be checked/selected? - Speedi IP: Logged

M3_Driver02 Junior Member Posts: 1 Registered: May 2002	posted 05-24-2002 04:52 PM I picked up my 02 M3 today...and I notice that when i shut the car off...that the engine shakes alittle/vibrates. Is that a normal thing??? I am also picking up some vibration on the clutch. I only have 120 miles on it as of yet. They also said that i can't go full throttle at all...so if in the future i happen to do it by accident...and something breaks...will i still be covered under my warranty? Thx! IP: Logged
gsawyer Junior Member Posts: 2 Registered: May 2002	posted 05-30-2002 07:39 PM I'm taking delivery of an M3 at the end of June, 2002 (on a boat from the Fatherland right now). I want to get everyones opinion, after reading these posts, if it would make sense to ask for a DME print-out the day I take delivery? This would show if someone in Germany or San Pedro port revved the shit out of the engine. Do you think the dealer will accomodate me? IP: Logged
M3Lover Member Posts: 62 Registered: Dec 2001	posted 05-30-2002 07:52 PM I think they have to take out the unit to send it off to have it read. I doubt they would do that. Everytime you take the car in for service they could test drive it. The possibility is that someone could abuse it. Since there is no timestamp, they can not prove who over-reved it. I read that they fixed the engines for the december production. You are probably fine. Just follow the break-in period. IP: Logged
M3Lover Member Posts: 62 Registered: Dec 2001	posted 05-30-2002 07:55 PM M3_Driver02, do you feel the clutch vibration as it is being shut-off? If so, you are describing situations that exist in my car too. The engines sounds horrible when it cuts off. I found that if you shut-off the a/c compressor before you cut the car off that it helps some. IP: Logged

M3, thanks for your thoughts. I am slated for a November 2002 production (2003 model year). Now I'm getting nervous about this engine....should I just back off the list? IP: Logged
M3Lover Member Posts: 62 Registered: Dec 2001	posted 05-31-2002 12:01 AM I would not be nervous. Out of all the cars produced, the number failing is low and I believe BMW will stand by their cars. If I had to do it all again and I knew all of this information, I still would get the car. You will have no regrets. You will love the car!!! IP: Logged
Dekard Member Posts: 26 Registered: Jun 2002	posted 06-11-2002 10:31 PM LorenzoNY, I'm in the same boat as you. Slated for November 2002. Hope they fix the problem, I know a lot of people that want this car! IP: Logged
hrb93 unregistered	posted 06-13-2002 08:52 AM I have been reading the engine failure threads for a while and a couple of things have been bugging me. 1. If you buy a new car and the engine blows up (does not matter how it was done) it should be replaced or the whole car for that matter. 2. They have tried to out do themselves with a small capacity Normally aspirated engine. It has come back to bite them. Solutions, 1. BMW run the engines "IN" in germany. 2. lower the Rev limit if this is the problem. So the premium paid for a car that is meant to handle spirited driving does not. IP: Logged
Dekard Member Posts: 26 Registered: Jun 2002	posted 06-13-2002 01:06 PM To the guy asking about the DME printout when you get the car... Did you find out if this is doable/reasonable thing to ask for? As far as over-revving, I think these s/w engineers at BMW should add features which slowly increases the rev-limiter rather than have it fixed at ~8000. Algorithm should go something like ~5000rpms < 1200 miles, then allow it to gradually increase to 8000rpms by say 5000miles? IP: Logged
DRV Junior Member Posts: 1 Registered: Jun 2002	posted 06-16-2002 11:27 PM Reading all the engine problems with M3 I wonder if I have made a wise moved. Just sold my 2002 is300 wich I had driven hard even at 200 miles new, going to 140 mph. In 4 months put 9000 miles with no problems. I have ordered my dream car production 6-21-02. Can not wait to have it, but concerned. Just have to take a Valium and drive slow for 2,500 miles. IP: Logged
