Fuel Usage Between Those In The Draft And Those Not

Well, I've been trying that strategy for years (both in GPL and N2003, and
both online and off) and it only worked for me once, which I attributed to a
fluke.  And while the DTE (distance to empty) in GPL's setup menu screen was
usually accurate, N2003's was not only wildly off-the-mark but also jumping
all over the place (altho the in-car F3 screen seemed trustworthy).  I just
assumed the feature was broken, like so many other promising might-have-been
in the games (like GPL's adaptive AI and N2003's brake wear).  I'm glad it
works as it gives me one more arrow in my quiver (when yer as old & slo as I
am, you need a lot of canny gotchas to win races).

The last time I remember it working was in Indy 500, Papy's first sim.  When
I complained to Dave Kaemmer that the game was getting too easy (you
couldn't adjust the AI), he recommended that I turn down the boost, which
went from 1 to 9.  I finally got to where I could win races with it set at 1
by a clever combination of rpm-preserving line and aggressive blocking.

I did notice that you could save one fuel stop in the 500 (5 instead of 6),
but by itself that wasn't enuf to win (saving 30-40 seconds--there was no
pit-lane speed limit--over a 3-hour race wasn't sufficient to recoup the
lost speed), which might have worked in the RW but not in "Indianapolis 500:
The Simulation."

My best lap in that game was a 242.  Anybody beat that?  (Without altering
the wing angle during the lap, that is.)  I saved the screenie somewhere....

Fuel gauge is suppose to flutter in N2003 as it models real life.  There is
no fuel telemetry in NASCAR, only a fuel press gauge and crew calculations
done manually.  Been more than one race lost in NASCAR due to "hoping" you
had enough fuel.  Basically when the fuel gauge starts to fluctuate your on
the verge of running out but not clear exactly when it might happen.

Re-read, please.  I was referring to the "Fuel Level: x gallons to x laps"
value in the setup menu in the garage, which doesn't flutter.  The fuel
PRESSURE gauge in the***pit isn't supposed to flutter, either...until yer
almost outta gas, that is.  (If you see it start to drop on a road course
after you've passed the pit entrance, you can stick a fork in yerself - yer
done.)

    Steve, I can remember a C***te race on Ten where I loaded a
Tally setup instead by mistake. I had a really low numerical final gear
ratio 3.05 or 3.10. It was a 50% race. Even though I had the slowest
car I ended up winning the race because I did one less fuel stop than
everyone else.
    That was Nascar 2 I can't say I ever tried it with any other version
but it did alter the fuel rate fairly significantly.
    I also recall running 242's in Indy 500 with the Buick.

Experience has shown that, from the instant the spotter gives his
low fuel warning (the first one), which is usually followed by the
needle starting to drop a few seconds after the message, you
will be able to drive about 7 miles before the engine starts to
sputter, and one more mile after the sputtering commences.

OK thx, I'll look into it. I didn't think it was right that they could
do more laps than me on the same fuel load but then I thought maybe
it's my poor driving style or becauase they are drafting. I could be
right still.

<shrug> I got the warning the other day right as I was going into
Dunlop at Le Mans.  I was sputtering but managed to get it into
the pits before she conked out.  That's about 8 miles right there,
on a track where you're running flat out most of the time.

If you're just following someone at the same speed as them, your rpms will
be more or less the same.  You also won't be using full throttle, as if you
were, you'd be catching up with them.  This is why you will use less fuel
than the guy infront, his car is doing all the hard work punching the hole
in the air.

I think that's the key question.  Does NR2003 actually monitor the true
throttle position, or are all fuel calculations done on a rpm vs. gear vs.
distance vs. ?? equation?

I know this.  I've tried running pace laps in 4th gear to keep rpms down,
and it didn't make a bit of difference in the fuel usage.

That's why I'd love to know what the exact parameters are Papy is monitoring
for fuel usage calculations.
