#1. Water wetter and BMWs - from Marc.S.Edwards@QuestDiagnostics.com

Date: Fri, 4 May 2001 13:48:44 -0700 From: Marc.S.Edwards@QuestDiagnostics.com Subject: Water wetter and BMWs A.J. asked: From: "DiVincenti, A.J." <ADiVin@lsuhsc.edu> I don't know if this has come up before. Is it safe to run Redline Water Wetter in an E36 M3 with BMW coolant? Do any of you use this product? A.J. Reply; I have used water wetter in both of my 95 M3s. Both have been tracked and autocrossed and have survived in the chill of the Indianapolis winter and the summer of the valleys of Los Angeles. I have not had any problems either way. In a normally functioning cooling system I'm not sure that it adds anything over the regular coolant. Perhaps the surfactants will slightly increase contact with the metal surfaces allowing that extra margin. Or, in particularly high-heat situations it might add that small margin of safety if not just peace of mind. I'll continue doing it but I don't have any hard facts and data that it does anything. I do keep a bottle in my track kit because in an emergency, if you blow all your coolant out, you can add the water wetter to regular water and it should function just fine to get you home. For that matter so can water if you don't have to worry at all about stop and go traffic. So that small bottle of orange/pink stuff in my track box is another 'spare" that I carry to the track.

Local club members have been putting water wetter into their track and steet M3s running with and without coolant. Works equally well both ways. Some track events require that participants put only water in the cooling systems (aka Porsche clause) to minimize the excitement of the drivers behind you when the coolant system suddenly decides to let go. > I do keep a bottle in my track kit because in an emergency, > if you blow all your coolant out, you can add the water wetter > to regular water and it should function just fine to get you > home.

Coolant is there to prevent pure H2O from freezing and bursting your engine when the ambient temps drop below 32F. Nothing to do with cooling efficiency. alex f

I downloaded one of the PDF documents (specifically, SMG2 in detail), here is a quote: "Moreover, the gearbox can be shifted down by pulling at the left rocker switch or by tipping the selector lever forward. Depending upon the driving program selected and the individual driving situation, the engine will automatically double-declutch like an experienced driver, so that dropping a gear can be done faster and more smoothly. Gears can be ³skipped³ as desired if the rocker switches or selector lever are operated repeatedly. However, these shift commands are carried out by the electronics only if it is possible within the wide rev band of the M3 engine. Over-revving the engine in any driving situation is therefore excluded." - Rich

Good questions, but I don't know. However as of about a year ago there apparently wasn't a Koni c/o kit for the M3, although there may have been for other E36 models. I get around a bit and know plenty of people using regular Koni SAs, but haven't heard of anyone with these coilovers. All of which makes me wonder, hence the post. I was hoping that somebody who is currently in the market for Konis will find out and let us all know. Neil 96 M3

That's always been the popular speculation, correct or not. It sure is a PITA having the staggered sizes though. Neil 96 M3

Our autocross courses in North TX tend to be in the 1:30.xx range though. The tires heat up and wear very well when the suspension is setup properly even on this length of run. It also helps that I ran the autocross program & design the courses (and would sometimes put a 4 cone slalom at the start, for this very reason). Just a small perk of volunteering to run the program :-) I would typically get 6-8 weekends (both DEs and autocrosses) out of them.

Date: Sat, 5 May 2001 01:27:43 +0300 From: "bcg" <cgunes@amideast.org> Subject: RE: [E36M3] SMG II Hi all, I have a 98 euro m3 with smg1. I'm very happy with smg. The gear changes are smooth and fast. I'm sure the smg2 is a much better and refined system. I think on the track the smg system is superior to standart because you dont need to heel and toe. -In manual mode it should operate like your six speed -manual where you can make a mistake and screw up the -gear box. I guess you'll still have people not being -able to brace themselves at a turn and accidently -downshift With smg you cant overrev your engine by selecting the wrong gear. The cpu of the smg monitors the road speed and engine speed and if the selected gear is lower than it should be than the clutch isn't released until the road speed is down to the predefined level for the selected gear. -However, if you're coming to a 2nd gear -corner from a nice long straight in, say 5th gear, does anyone know if you -can preselect the number of downshifts you want. I mean, can you just tap, -tap, tap, and once you're slow enough you'll be in second gear, or do you -have to physically wait until the revs are appropriate before selecting the -downshift? Yes, you can do that with smg1. Once the revs , road speed and selected gear matches, the cpu releases clutch. It even does rev matching for you. Btw: this is the reason why you can't change the differantial ratio in a smg bmw. If you want to change the diff ratio than you should reprogram the default values for road speed for each gear. Cem
