---------------------------------------------------------------------- Date: Tue, 01 May 2007 08:31:09 -0800 From: bbarry <[EMAIL PROTECTED]> To: Matt Bader <[EMAIL PROTECTED]> Cc: [email protected], [EMAIL PROTECTED] Subject: Re: (Mileage) Message-ID: <[EMAIL PROTECTED]> In the hidden codes on the OBC there is a correction factor that can be entered. It takes from .750 to 1.125 iirc. Numbers out of that range are not accepted when pressing 'set'. On my 3.5" MAF tube, stock MAF sensor, Turbohoses intake boot, ASC throttle body removed, UUC Viper airbox, 24# injector, 4.5 bar fuel pressure, M50 manifold, Dinan stage 1 s/w, 3.38 rear end, '97 E36 //M3, making 251 rwhp SAE, I calculate between 20.5 and 25mpg between leadfoot and steady highway with cruise control. With maximum correction factor entered, the OBC still reads 21% to16% higher. The variance from tank to tank due is to time spent idling and how full the tank fills to. A proper part throttle ECU mapping for this setup would improve economy, but no one does custom remaps for OBDII anymore, and a lot of people have bought unnecessary cams and euro MAFs to get the same or less power because of it. When the motor and differential were still stock I got a steady 22-3 in mixed local/highway, and highway MPG on steady cruise at 75 would go as high as 32mph in midsummer 80+ degree air, typically more around 26-8. at higher speeds.

Me too. The only problem with the M Roadster is the puny (12.5gal) gas tank which does restrict the range of the car a bit. Otherwise I love it, I would love to have that drivetrain in an E36 chassis - I am about to be jealous...

Taking out tire height and gearing differences, a quick analysis of weight to power ratios gives a glimpse into the anticipated performance. While this S54 is staying internally unmodified at this point, it is getting long-tube headers and free-flowing metal matrix cats, a combination regularly shown to generate nearly 370hp (crank) on the E46 M3s. Bench racing numbers: E46 M3 - 3415lbs, 333hp 1b/hp=10.25 Z3 M Coupe - 2940lbs, 240lbs with 240hp S52, lb/hp= 12.25 with 333hp S54, lb/hp= 8.83 Z4 M Coupe - 3108lbs, 333hp 1b/hp= 9.33 E36 M3 - 3150lbs with 240hp S52, 1b/hp= 13.12 with 333hp S54, 1b/hp= 9.46 with 369hp tweaked S54, lb/hp= 8.53 My M3 is already fitted with the E46 M3 6-speed gearbox, 3.64 diff, more weight dropped thanks to BBS wheels, Recaro seats, UUC exhaust, UUC brakes, and all my hot air. - Rob ----- Original Message ----- From: "Jamie Howton" <[EMAIL PROTECTED]> > > 20mpg on a mixed commute is in the "happy" range for me with a fun car with > > a strong motor. > > Me too.

I don't drive an M3, but my car (E46 328Ci) has the same tire specs as the later M3s (225/45-17, 245/40-17), and the PS2s are by far my favorite tires. I've tried the Conti SportContacts (suck), Yokohama AVS Sports (OK, but got very noisy and tramlined like mad), S03s (good grip, but a little soft), and the PS2s. Life from them is good as I can get into the mid to high 20k miles on them with a moderate amount of track schools. The grip is really good, and they just feel right with the stock suspension of the car, almost like they were designed for the car --- I can't explain it any other way. Wet grip is really something else, much better than the other tires. It's also the first set of tires that I've worn out and replaced with the same tires instead of switching. --Andre ------------------------------ Date: Tue, 01 May 2007 12:55:08 -0700 From: Kazuto Okayasu <[EMAIL PROTECTED]> To: [email protected] Subject: Re: <E36> M3 tires Message-ID: <[EMAIL PROTECTED]> At 11:43 AM 5/1/2007, Andre Yew wrote: I've put about 2k on a slightly used set of PS2s now. And though they're good, I don't think they quite live up to the high praises everyone seems to have for them, especially considering what they cost. They're slightly noisier than I expected, and grip and traction is VERY VERY sensitive to tire pressures, unlike any other tire I've ever used. At 'track pressures' (~30-32psi cold), they're pretty good. At 'street pressure' (~38-40) they're almost as bad as P Zero Rossos, that is, not so great. The Falkens I had just prior weren't as good overall (and really went away when heated up), but were fairly consistent at different pressures. We'll see how well and how long these wear. So far, I'd recommend em if they were $175. But not so much at the $230 my size costs. >I don't drive an M3, but my car (E46 328Ci) has the same tire specs as the >later M3s (225/45-17, 245/40-17), and the PS2s are by far my favorite >tires.

The biggest problem I have with the Toyo on this car (on higher-profile 16"ers) is that, compared to the old Dunlop 8000s that were on it before, the sidewalls flop over way too early, and probably for related reasons, have really sloppy turn-in. I hate to say it, because they're so noisy and they get a lot of grief because of it, but I still like Yokohama ES100s.
