Re: [uuc] Need advice on '97 M3 ---------------------------------------------------------------------- Date: Fri, 11 Jul 2003 15:08:08 -0700 From: [EMAIL PROTECTED] Subject: [uuc] re: Aux Fan (I want high speed only) Actually, you will just connect/jump the hi speed wires and forget about the switches. The methods below will only kick the fan on at hi speed once the temps reach the low speed switch temp. Another thot is to install a lower temperature hi-speed thermal switch. Essentially buy one or modify a low temp switch and install it on the hi side. Last thot, you really should get your cooling system checked out b/c you are only covering up the symptons. Have not been following this thread so apologize if anything is redundant. Grant re: Aux Fan (I want high speed only) was Fan: This can be implemented by snipping the high speed wire from the high temperature output of the switch and reconnecting the wire to the low temperature side of the switch. I did this in conjunction with removing the mechanical fan entirely. On the //M3 I also got some more air to the radiator by removing the plastic cover that sits over the electric fan, and cutting out some of the plastic of the shroud that runs from behind the grill to the radiator. The temperature guage needle never reaches vertical now. Before that it would sometimes barely get vertical on hot days in slow traffic. Add a bottle of Redline Water Wetter to the radiator and you'll be all set under any temperature conditions on the street. ------------------------------ Date: Fri, 11 Jul 2003 15:12:06 -0700 (PDT) From: John Bolhuis <[EMAIL PROTECTED]> Subject: [uuc] Re: E53 white turn signal indicators (full set) where is the best pl ace to purchase these?

In addition to common automotive functions like rpm and dwell (when's the last time you set dwell?!?), it also has a duty cycle function. It's about a 2 or 3 hundred dollar meter. Finding a place to hook into the fuel injector harness is the harder part.

Those 20 foot wheels are hard to come by, I think the biggest they use on Monster Trucks is what...about 5-8 feet. You might have to look in the "Earth Moving Equipment" catalog for the size you desire. :-) But, if you really want 20 inchers, I would agree that BMW usually has very nice wheels for the weight/strength if they have the proper offset and the X5 has at least one 20" option (and come standard on the X5 4.6is I believe) if not more. Also, Tire Rack has some 20" wheels. www.tirerack.com Best regards, Rich ------------------------------ Date: Fri, 11 Jul 2003 18:32:14 -0400 From: "Michael Lawrence" <[EMAIL PROTECTED]> Subject: [uuc] question about an E39 528i AC Group, My mothers 97 528i AC died on her a few days ago. I am not there to look at it, but wanted to get some ideas for trouble shooting AC worked fine, car was parked for about 5 days. It was cranked, left idling with AC on for about 3-5mins, while they unloaded another car. Suddenly smoke was visible, but it did not have a electrical smell to it, just a chemical or oil smell. I figured this was the freon coming out of a busted line. It was taken to a local shop that basically only has gauges and r124, no knowledge of BMW systems and very little knowledge in general. Here is what they found. Pressure on the high side (I believe, but not positive) was 100psi. When they tried to add freon, it would not accept any. Also with the compressor would not come on. Compressor was hotwired, no difference in pressure. >From my past experience, the pressure woudl usually drop to around 25 PSI when the compressor kicked on. Anyway, the system would not accept any more freon and when they tested the line fitting. It released all of the pressure in less than a second, meaning it had very little volume in the line. So, I am thinking a blocked hose or filter screen not allowing the system to be charged? What steps should be taken to trouble shoot this? I dont like AC work and have done very little myself short of changing dryers and expansion valves, converting to R134 on a E34.

Would welcome any thoughts from those experienced with E36 M3's. From web searches it appears that there are at least two issues of concern: rear sub frame tear out and loose oil pump nut. Car has 44k and appears to be in excellent condition. On of the PO's fitted the car with matched width M contour rims. Front rotors are heavily worn - likely close to their wear limit. Carfax is clean. Thanks, Peter ------------------------------ Date: Fri, 11 Jul 2003 18:28:38 -0700 From: "KKiely" <[EMAIL PROTECTED]> Subject: RE: [uuc] How to measure injector duty cycle? Jeff, Your question is vague. Duty cycle will tell you the percentage of on time (wether saturated or peak and hold type) but will vary with RPM. Also how can you do a comparison if you haven't already measured the non-modified head? Are you trying to determine flow rate and thinking that the head needs more flow? Unless you're also running a turbo it's doubtful you're bumping up against peak output at peak power. - -Kevin ------------------------------ Date: Fri, 11 Jul 2003 18:41:29 -0700 From: "Brant" <[EMAIL PROTECTED]> Subject: RE: [uuc] How to measure injector duty cycle? Jeff - Either a Fluke 87 or 88 (and possibly the 78) Digital MultiMeter will measure duty cycle. The 88 reads out in milliseconds (and may have a duty cycle option) and the 87 reads duty cycle directly. Just hook the meter positive lead to the injector ground wire (the one that goes to the computer) and the negative lead to a good ground. You can also do this with a dwell meter. Set it to six cylinder. Whatever dwell it reads, in degrees, divided by 60 is duty cycle. Of course, the premere method is with a Digital Storage Oscilliscope, but if duty cycle is all that you want, it is overkill.

(O-scope seems like overkill.) take a look at http://www.extrememotorsports.com/g1cat/afgauge.htm specifically at "EFI Systems Air Fuel Ratio/Injector Duty Cycle Meter" $100. works well. you get A/F monitoring with it too. there are other sites that sell this device, but most have it for $150 or so. other similar units out there, but also in the $150+ range. just as a note, it probably would be best to get some baseline data from a stock 535 for comparison. you can tap into the injector wire in the box under the hood on the passenger side. (either the wire for bank 1 or bank 2. doesn't matter which one. see bentley manual for colors and location) you can then run the wires through the vent hose thingy from the ECU compartment under the hood into the glove box area without drilling any holes. you can get to the O2 signal wire in that box too. hth - -Michael McCoy - ----- Original Message ----- From: "JSN" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Friday, July 11, 2003 3:13 PM Subject: [uuc] How to measure injector duty cycle? > Hello - > > Is there method to measure the duty cycle percentage of your injectors? > I'd like to do this myself so simple devices and / or layman's tools > appreciated if possible.

Well, those are two *well discussed* issues, and I'm not sure if the rear subframe issue applies to M3s (I've heard it mostly in regard to non-M E36s). The oil pump nut is an issue, but how big on non-tracked cars, I'm not sure. My data points: Had the nut come off the race car (ruining a weekend in Vegas, not to mention the motor), but the nut on the M3 was OK (but secured none the less). More common areas to pay attention to are: Rear shock mounts (RSMs): These wear out fairly frequently. Good replacements are solid ones from either JT-Designs or Ground Control. Cooling system: Although the '97 you're looking at shouldn't have the plastic water pump impeller that plagued earlier M3s, the cooling system is still a weak spot. Failure of the upper radiator neck is very common. I've had the entire cooling system on both my E36s overhauled. Power steering: Hoses usually leak at the bottom of the reservoir, due to the cr*ppy factory crimp clamps. Replace with true hose clamps. There's more I'm sure I'm forgetting at 11PM (and several beers :-)) - search the archives, both UUC and E36M3 (http://www.bmw-m.net/) >Car has 44k and appears to be in excellent condition. On of the PO's >fitted the car with matched width M contour rims. Good upgrade, IMO. >Front rotors are heavily worn - likely close to their wear limit. If the previous owner/dealer won't take care of that before purchase, they are fairly easy to replace yourself.
