Thanks Jim for all your priceless contributions to the BMW community.
: No Steve.. it's not theory. it's reality.
: Here's one for you..
: Go take a stock car and dyno it today..
: Now go dyno it 3 weeks from now.. without
: changing anything except time and possibly the
: fuel if you get a new tankfull (likely). Also
: wait another 2-3 weeks and do it a third time.
: Come back to me with the results..
: Although I already KNOW what you'll find..
: You'll find a measurable CHANGE (up or down, can't
: predict) in the power.. or the midrange torque
: or both..
: That's because you motor is ADAPTING to the
: exact environmental conditions it finds at
: the time you are driving (or testing) it.
: (That's why I always say to go and test your
: car, same day, same dyno.. it's also why
: I tell people that dynoing these cars is
: a waste of money for the average joe)
: This horsesh*t about "returning to stock" is
: getting ridiculous.. I've not intended to get
: off on a rant here, but here goes:
: I think I've probably dynoed more OBD-II BMWs
: that this whole list combined with every other
: tuner in the U.S.(spare Dinan).
: I've DONE all this research for one reason and
: one reason only.. to be SURE that when I tell
: you something it is 100% true, and NOT bullshit.
: (Yet every week, I have to defend myself against
: someone with a fresh notion)
: You or your friend simply as a private individual
: cannot afford the amount of research that we've
: done on these cars... unless you're both crazy
: and independently wealthy.
: As far as the "theory" it's PROVEN in PRACTICE.
: I just got done assisting the owner of a forced
: induction car who was having all sorts of little
: nightmares with mixtures changing. When he
: listened to me, he was able to RETUNE the car
: himself and now his car runs better than any
: of the lot from the well-known tuner he bought
: his forced-induction kit from.
: (Imagine that)
: It really does come down to the fact of you either
: listen to me, and believe what I say, or don't
: If you don't, continue to throw money the way of
: the dyno operators, so they can place more ads
: and further the current "dyno mania" that really
: does nothing by make the dyno operators rich.
: Because it really does come down to that.
: Most "average Joes".. heck, most "racers" can't
: afford to spend the time and money on the needed
: testing. Further, they don't have the scientific
: knowledge to interpret the readings.
: Yes, folks.. you really do need to INTERPRET the
: readings to see what is going on. You need to
: know how that particular breed of car behaves (or
: not) on the dyno.
: Some cars lose power 1st to 2nd run.. some gain.
: Some cars adaption is so weak that they never
: change power at all.. some is so active that
: merely running it at the wrong midrange RPM for
: a few minutes can throw off all the results of
: your session!
: It's sort of like YOU looking at your own CAT
: scan trying to find the problem. It isn't
: likely to yield any worthwhile results.
