#3. ODBII Error Code. - from Jeff Kumler

Date: Fri, 23 Mar 2001 11:19:23 -0600 From: "Jeff Kumler" <jdkumler@comdisco.com> Subject: ODBII Error Code. The CE on my '96 M3 came on a couple of weeks ago and I finally had the code pulled yesterday. The only problem is that the car feels a little under-powered. 65 - Camshaft Phase Sensor 222 - Coolant Temp Sensor (time to engine temp threshold) Had the CE reset and it came back on after about 10 minutes of idling, code 65 again. Estimate to replace the sensor was about $220. Can anyone provide more information regarding these codes??? Would it cause the car to retard timing? Any help/insight would be appreciated.

#7. Re: Valve Float versus Resonance - from RogRacer@aol.com
Top
Date: Fri, 23 Mar 2001 13:14:13 EST From: RogRacer@aol.com Subject: Re: Valve Float versus Resonance Chester, et al. Valve float and spring resonance are two different things. A hypothetical MASSLESS spring will have infinite INTERNAL natural frequencies (resonance), but if it is not stiff enough for the mass of the valve, lifter, etc it will NOT follow the intended cam profile, i.e. - the valve will STILL float. This is NOT "spring resonance" - our hypothetical massless spring has infinite natural frequencies! It is a simple case of the spring not being stiff enough to follow a cam profile given the weight of the items it needs to move. Spring resonance has to do with the natural frequencies of the spring itself, which are a function of the spring material properties (including weight) and geometry. It is a seperate effect, but if not properly accounted for, can also prevent the valve from following the intended cam profile. Roger W.

But in this case, you'd probably want to set the origin of your coordinate system at the point where the object is at rest. In the case of the valve, that would be when no force is applied by the cam, so the position of the valve would be at the valve seat, not halfway open. In the case of the speaker, it would be the point where the suspension of the cone positions it when no signal is applied to the voice coil. That would be at the approximate midpoint between it's maximum positive excursion and negative excursion. Specs for cams describe lift and duration. Lift is always a positive number, with the zero reference being the valve seat. Specs for speakers describe maximum cone excursion with the zero reference being the cone at rest. The speaker cone will move +/- the excursion distance, referenced to the rest (or zero) position. -rb >From: Skip Bogard <Skip.Bogard@ALUMni.DUKE.edu> >Reply-To: Skip.Bogard@ALUMni.DUKE.edu >To: Ron Buchalski <rbuchals@hotmail.com> >CC: e36m3@bmw-m.net ^^^^^^^^^^^^^^^^^^^ (not private!) >Subject: Re: [E36M3] Re: Solid Valve Lifters >Date: Fri, 23 Mar 2001 12:40:31 -0500 > >PRIVATE MESSAGE. ^^^^^^^^^^^^^^^ > >Ron, >The origin in a coordinate system is arbitary.

The Eibach rear spring is significantly stiffer than either the stock or H&R Sport (which are similar in stiffness). This is why they look different and why they are shorter even though the ride height is higher. Remember ride height is a function of both spring initial length and spring rate.

#10. BMW springs and eibach part numbers - from TFRM3@aol.com
Top
Date: Fri, 23 Mar 2001 15:01:19 EST From: TFRM3@aol.com Subject: BMW springs and eibach part numbers Chuck Roberts Sez: "Front & rear spring #'s are 2017.101." This is the correct part number for the front only. The correct part for the rear is 2034.002, and will look COMPLETELY different. All the springs; stock, HR and Eibach should look pretty much the same for the rear. The lengths may vary, and are not necessarily indicative of final ride height, due to progressiveness and wire diameter. However, even if they are made out Chrome-Moly steel, (which actually is not a spring steel) the specific alloy makes no difference in stiffness. Your best bet is to call who you bought the springs from and double check everything.
