One of the most glaring was the over rev problem....All E36M3's can be mis-shifted. While instructing last Sept at an Autocross school in my 98M3/4 I went to shift from 2nd-3rd and caught 1st. I was able to get the clutch to the floor fast enough .....but still stored a 7552 RPM over rev.......The dealer caught this and warned me that a 2nd offense would void the warrany with the term "race conditions".............Whatever that means :-) Of course the car is fine..but talk about having your gut in your throat for a few minutes...... What's interesting is I have zero problem going thru the M3 gear box on downshifts....all you have to do is backhand them......but that 2-3 upshift shift is scary.....i've gone from 2nd-5th a few times......so much for that timed run :-) but no damage to the motor.... Regards, Steve

#4. *sigh* more pulling - from Kit Wetzler

Date: Thu, 17 Aug 2000 17:46:40 -0700 From: Kit Wetzler <kitwetzler@mindspring.com> Subject: *sigh* more pulling Argh. Ok, the car has been aligned 3 times now. It still pulled to the right pretty hard, even on totally flat roads... or even on roads that are camfered to the left. It's not just following the crown of the road... the car pulls hard enough to change lanes if I let go of the wheel. The specs are : left right camber -.7 -.9 caster 7.2 7.2 toe -0.01 -0.01 Any suggestions? The caster is a few tenths too high. Should I try a set of camber plates? Could a bent wheel possibly cause this? When I bought the car, it didn't pull... I got a new set of tires and now it does. The tires have been swapped, side to side. I can try running the tires backwards... (they're directional Yokohama AVS Sports) Think the belts could be bad on the tires? If so, I should be able to get new tires out of the shop... Let me know if you guys have any suggestions, please! -kit, the frustrated 97 M3/4 owner

I would think that the Shark Injector would only overwright the program areas (including any lookup tables) and probably adaption but not the data that wouldn't need to be erased - like serial numbers, overrev info, EWS stuff, milege?, etc.. This info is based on experience with Motorola Powertrain controllers for OBD-II cars. I don't think that BMW uses a Mot chip but the operation should be similar. -Matt --- andy radin <fourfa@mindspring.com> wrote: > Date: Thu, 17 Aug 2000 13:31:01 -0700 > From: "andy radin" <fourfa@mindspring.com> > Subject: Re: [E36M3] Over Rev's > > "Actually, what I was trying to say was that, as far > as the over-rev code is > concerned, the dealer can't erase it.

I've always been able to "fix" the pulling by swapping the tires from side to side or front to back. Is the spare a front size wheel? if so, try putting the spare on in place of left or right to see if that fixes. something has to fix it. damn annoying. I know how you feel... Jason

You can slightly bend a valve, allowing the engine to run just fine, for a while. How long? Hard to say. Depends on how much it was bent ;-) 2) The engine does not turn backwards. It goes the same direction, just really quickly. If you spin it over about 7400+ RPM the valves won't be able to keep up and will eventually touch the piston. You could send something through a block but it's much more common for the valves to just bend a little. Which is still very expensive. -Matt --- S Lafredo <slafredo@yahoo.com> wrote: > Date: Thu, 17 Aug 2000 13:14:01 -0700 (PDT) > From: S Lafredo <slafredo@yahoo.com> > Subject: Re: Over Rev's > > Dude, > > I think when the car is "truely" overreved a part or > two flys through > the block.

At a minimum you would bend a value. >Hopefully, you would notice either of these rather quickly ;) Sometimes, depends who's driving. Little story..... Back up 3 years... I'm shopping for an M3 in Bellevue, Washington. So I go over to the snakes at this exotic car dealership (Park Place Motors). They have this nifty LTW with most of the goody LTW stuff missing (this is the future infamous ML LTW, note that ML added all the good stuff back on, right on!). Salesman claims the car has 286HP and is a "Canadian" model. Uh, huh, pop the hood smarty. Yeah one throttle body, OK. On the other side there's a nifty Daytona or Technoviolet Dinan SC M3. Salesman claims the LTW feels faster than the M3 with the big squeakin' belt. Okaaay.... so I ask for a test drive. This thing drives like dog shit, actually worse, I can tell one cylinder at least is not firing. I tell them that. Salesman says, "oh it was just detailed, probably water on the engine somewhere." Next day at "Strictly BMW"...one violet SC M3 getting an over-rev fixed. Yuh-huh...snakes! -Carlos Motor City Chapter __________________________________________________ Do You Yahoo!?

#9. Looking at 320i race car, any thoughts? - from Pieter Van Dien
Top
Date: Thu, 17 Aug 2000 21:56:10 -0400 From: "Pieter Van Dien" <pvd1@worldnet.att.net> Subject: Looking at 320i race car, any thoughts? I'm considering a 1977 320i race car. This car was originally set up for BMWCCA racing by Black Forest Tuning but has been used for round-abouts and auto-x for the past year or so. The car has no fan, instead using an electric unit. The interior is entirely stripped and a full cage has been installed with bars to at least the rear shock towers, maybe the front also. I would use this car for driving schools, SAFE events, auto-x, time trials, etc. and possibly BMWCCA racing at some point. This would be a "learning platform". As I understand it, this car could never really compete in SCCA racing, except maybe in GT which is very expensive. So, what's the M3 content? M3 would probably have to go, at least temporarily, in lieu of a tow vehicle. Any thoughts on this car and setup? Would this be a fun car to drive? Piete
