That's about the time they came out with ver 3.2 and Amber Gore advised me to download the upgrade...I did and it "popped right in." They have now introduced ver 4.0.... remember, all software upgrades are free.... I'm not associated with them, I just feel good about finding something that works and at a reasonable price. regards.....r3 97 M3, Siver/Black 86 325, Red/Beige xxxxxxxxxxxxxxxxxxxxxx original message xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx Tripp, That's great news - when I tested the earlier ProScan 3.1 for the Roundel article which will be coming out in May - it had some real problems with the BMW interface. David Gore had sent me email last week about the new version - and that the BMW problems had been solved. I'll have to take a look at it and see if Satch will publish a quick update for the article in a future issue. Thanks!

#4. Am I smelling coolant?- from S Stiles
Top
Date: Sun, 26 Mar 2006 12:56:00 -0800 From: "S Stiles" <stiles_s@hotmail.com> Subject: Am I smelling coolant? <sigh> Issue first, then a quick vent. Seems like I'm getting an occasional whiff of sweet coolant smell in my '97 M3 after the heat kicks on. I don't see any leakage on the carpet, and no "low coolant" messages (I think the coolant is holding pretty steady). Any ideas? On my old cars, this would mean "heater core", and "now go tear apart the dash and the car will never be the same again". Same w/the M3? <vent> Bought the M3 about 6mos ago, and have been playing catch-up w/this 85k-mile 1-owner car. Replaced rad, thermostat, hoses, suspension, rsm, rtab and a bunch of other stuff. On the to-do list is control arms, front wheel bearings, brakes, etc. Will it ever get to the point where I've replaced everything and it drives like a "like new" car for a year? Or, should I just dump it and buy a new GTI? :) </vent> Thanks, Scott.

I'm somewhat anal about changing fluids on the M3, but what about the plugs. I did a plug change at 25K miles and did not feel a difference. Now as I near 50K, I'm contemplating another change, if for no other reason then to check the tip condition. Car pulls strong, no hesitation, no problems (knock on wood).

You can get > readings all over the board from day to day, dyno to dyno... That sounds like a sweeping generality... Lets try to be more specific. Most dynamometers I've seen, heard of, or ran on have a margin of errors between 0.3-10.0%. A huge difference, to say the least. A significant part of the error is introduced by relying on the tires to transmit the torque from the engine to the measuring device. Dynamometers that mount directly to the wheel hubs would be expected to produce tests with a smaller margin of error. For example: Dynapack 3000 Series : +/- 0.3% http://www.ultimategarage.com/dynapack.html Dynojet 248C : +/- 3.0% (quote from the operator of a TX facility) Interestingly, neither Dynojet (www.dynojet.com) nor Mustang (www.mustangdyne.com) disclose their products' error margins or calibrating requirements on their web sites. Other contributors to the random dynamometer output variability are the environmental and engine adoption factors. Most of the people have heard of the former. If you run back-to-back on the same wheels/tires and in front of a decent air-cooling fan, you can expect comparables output #'s relative to each other. DME adoption, on the other hand, is a huge head-ache. I remember a talk Steve Dinan gave to the LSC member where he basically admitted that the only way to get honestly comparable dyno output #'s was to re-boot the DME before each run. However, that would not yield the true maximum output either as DME adoption would typically Here is a link to an article that discusses these issues: http://www.caranddriver.com/article.asp?section_id=4&article_id=8020 alex f > -------------- Original message -------------- > From: "Lawrence Barbieri" <larry@logicalconclusions.com> > > > Date: Sun, 26 Mar 2006 02:31:15 -0500 > > From: "Lawrence Barbieri" > > Subject: Lack of performance improvement > > > > I have a 95 M3.
