In the process of installing power for my V1 I decided to remove the SR motor. THEN I read in the manual you are only supposed to remove it with the SR closed. Crap. Now it won't go back in. Any ideas how to get that motor re-installed properly??? Crap crap crap.... Scott

#6. fuel starvation - AGAIN?! - from RFKoby@aol.com

Date: Tue, 29 Apr 2003 14:51:07 -0400 From: RFKoby@aol.com Subject: fuel starvation - AGAIN?! here we go again. yes, there is a definite tank change from 95 to 96 model cars. there is also some very subtle difference in the fuel pump, return lines, and transfer line. for those that know me, my 1995 M3, 9/1994 production, will run all the way down to the reserve light. I am driving the car HARD, and can turn laps faster than most others....... so it has nothing to do with how fast you are driving. I believe the difference comes from the actual fuel pump and the volume that it is delivering. but more so, what is important is the volume and pressure of the return fuel back to the tank. The return fuel line goes into the left side of the tank and is used to generate a "jet-pump-venturi" that is used to transfer the fuel back to the right side. the jet-pump-venturi is much like the old style jet-pumps that were used on wells deeper than 30 feet when the pumps were located outside the wells. if the fuel jet in the venturi is manufactured off by a few thousands, the resulting pump action is greatly reduced.... I haven't yet proved this, but this is how the "intended" system works, and this is the only explanation I have for the difference between car of the same year, make, model. bob 9/94 M3 turning fast laps, running on empty >--------------------  1  -------------------- >Date: Tue, 29 Apr 2003 10:29:59 -0500 >From: Neil Maller <neil.maller@gte.net> >Subject: Fuel Starvation > >I finally got fed up with the fuel starvation problem during track use >that's known to many of us, and ordered the Stage II kit that Bimmerworld >sells. > >Talking to James Clay (who certainly knows about such things) on the phone I >learned something that I never knew before: BMW made a design change to the >fuel tank that apparently makes later E36 models more susceptible to this >problem. > >Sure enough, when I went and looked it up in the ETK, I found that E36 cars >up to model year 95 have a 62 litre tank.

#7. Car pulls under braking - from AVUSM3@aol.com

Date: Tue, 29 Apr 2003 14:55:27 EDT From: AVUSM3@aol.com Subject: Car pulls under braking Mel - So far I have just decided to live with it. As long as you are aware of it it's not a big deal, although certainly not ideal! I like the idea of a bias valve for the right rear. This would be more value for a '95 than for the later cars since the '95 has 3 channel ABS vs. 4 channel in the later cars. Regards, John Date: Tue, 29 Apr 2003 08:27:13 -0500 From: "Mel Silva" <melsilva@mindspring.com> Subject: RE: [E36M3] Car pulls under braking Have you that track your cars considered using a brake bias valve on that right real line? Reducing the effective pressure to the right rear caliper should increase the effective pressure to the other calipers. Assuming of course that this is just a "characteristic" of the cars and not a mechanical problem. Mel

#9. Battery vent tube - from Wen Liew

Date: Tue, 29 Apr 2003 12:22:10 -0700 From: "Wen Liew" <wwliew@hotmail.com> Subject: Battery vent tube After being away for 2 weeks, my 96 107k car failed to start. A quick check with PepBoys revealed that the battery can't hold its full charge. So, I replaced it with a Sears Diehard. What is the function of the battery vent tube? If my guess of it venting battery fluids during evaporation at different temperatures is true, then the tube needs to fit into the vent hole to dispose of the fluids. Can anyone confirm this? Thanks.

Virtually all the BMW accessories, including the map light, work by supplying +12V (controlled or not by the ignition switch) directly to the load. The on/off switch is on the ground side. So the circuit goes: o +12V to first bulb terminal o Bulb terminal one to bulb terminal two via filament o Second bulb terminal to switch o Switch to ground. With the lamp switch off, but accessory power on, a meter will read +12V at *either* bulb terminal. A good meter has very high resistance, and draws so little current that the voltage drop due to the filament resistance is unmeasurable. So you can't tell which side is which without a visual check. If your V1 has its positive feed connected to the *second* bulb terminal, then the filament will serve as a series dropping resistor, reducing voltage to the point where the V1 won't work, even though the meter says you are connected to +12V. Solution: Check your circuit, and make your connection to the correct side of the bulb. One way to ID this is to follow the PCB trace back to where it should be fed by a violet/white wire. See Bentley page E-217. Or, it could be something else... Neil 96 M3
