It must have sponsorship from local independent BMW service shops.

That's what I thought was happening when I cranked up the FP a 1/4 bar on my car. As Barry has suggested, "mileage" went up. But I figured that had to be an illusion. I came to the same thought - that the mileage is really calculated by the duration and number of the injector pulses. If the fuel pressure is constant, then it wouldn't be hard to do. Adding more FP would increase the fuel delivered for a given pulse. The lambda circuit would shorten pulse to move it towards stoich and the computer would read this as "better mileage". At least I think this is what's happening... :) Bet if you run the car open loop the "mileage" will sink like the Titantic. Question: Will the check engine light come on if you up the FP to the point were the lambda circuit can no longer adjust the pulse width to keep the car in ECU's targeted range?

It's listed somewhere on the net. How to accurately determine it is another story. Marco <Snip> For my wife's '00 540iT, the scale factor is set to 1000 as a factory default. Sooooo.., check reported mileage against calculated mileage for 2 or 3 tanks of fuel. Of course reset the computer reported mileage each time that you fill up. As an example, if your calculated mileage (miles driven/fuel used) is 20.0 and the computer mpg displayed is 21.0, divide displayed mileage by computed to get percentage, in this case 105%. Multiply the 1000, remember the 1000, by the percentage to get 1050 as the new scale factor to enter in the computer. YMMV literally.

Hate to tell you this, but with the 24lb injectors in there, the trip computer MPG gauge is now completely useless. It is programmed to turn the pulsewidth of the stock injectors, into an "amount" of fuel used. Since you put in bigger injectors, your pulsewidth in closed loop operation is now much shorter (either due to adaption, or due to any new software you have in there for them). The trip computer is reading this as better gas mileage. It is false...

Highlights: - Initial low pedal. One pump brings it up nicely. Steady pressure will eventually result in a pedal all the way to the floor, nothing you'd notice in normal driving. - Rebuilt calipers, replaced front wheel bearings, replaced master cylinder. Multiple pressure bleeds. No improvement. I finally buckled and took it to the dealer so they could perform their fancy cycle-the-ABS flush. They flushed and gave it back saying it was all better. It wasn't. I think there is an improvement, but it's certainly not 100%. I took it back today and they brought out their lead technician to discuss the issue with me. He told me that there is nothing they can do with the ABS system while flushing in the earlier E36s, not until '96 or so when some sort of additional pump was put in the system. I was quite surprised as I've never heard this before. He said they would probably try an old fashioned brake pedal pump bleed because sometimes the pressure bleed doesn't use enough pressure to get all the air. Opinions? Chris B.

If it is, then try filling the brake system the way factories to it, pull a vacuum, then introduce the fluid. Gary Derian > > Well, got the car back from the dealer. Still not right.

My Bentley manual is useless on this point. I recall Brett had addressed this a while back, but I'll be damned if I can find it in the archives. And honest, Brett, I always took the pressure off the seat before lifting the lever. So, before I (try to) take it apart, does anyone have any tips as to the likely culprit? Is there a part I should buy before having a go at it? Thanks. Roger '97 328ic (power seats) ------------------------------ End of [bmwuucdigest] digest(15 messages) **********
