GPL. Good starts?

by Kev » Fri, 17 Dec 1999 04:00:00

I've had GPL for 3 weeks now and I'm not doing too bad but if I qualify
well (with the slow AI core.ini file) I lose my hard earned qualifying
efforts with ***starts.

I find that the engine bogs a lot with medium revs. If I try more revs I
spin off sideways :) I'm in the Murasama BTW (good car that) but I
assume the theory is the same for all.

(I have a MS wheel/pedals and a clutch button)

Thanks

Hi!

Why don't you spend an hour or so training starts? Just learn how to use
the clutch, how to accelerate out of stillstand, how to compensate the
rev-hit, when you release the clutch, and all that sort of things. The
track is yours during free practise, so use it! I've painted the whole
start-/finish-straight of Monza black until I got used to good starts,
but who cares? ;)))

Regards
Crash

The torque you get for a particular throttle
setting varies a lot with RPM. So as you
accelerate to higher speeds, watch carefully for
large increases in torque/horsepower. You may
have to throttle back a bit at the higher RPMs in
the lower gears to keep from spinning. This
may be surprising you until you are ready and
waiting for it.

Learn the sound and the feel of both rear wheels
at a point near breakaway and be able to stay
just under that. It doesn't take a _lot_ of modulation
(even on the Lotus), but it does require some.

Luck,

I used to qualify 1st at Silverstone in Pro-Long, and the AI always
crash me from the rear at first corner ! The only way to be safe is
to keep very at right when i brake and let pass 2 or 3 AI :o(

Do they have cold tire or not ?

Also,  i was so annoyed that i decided to catch an AI up and to crash
it from the rear, i did it on the 2rd corner ( left one ), i was happy , because
a thought it
was going to crash on the side road, but, instead, the AI crash me from
the right side ! I've watched the replay, and the AI managed to put right is car

a way it's impossible to do !!!

Is there a tweak for this ?

I know GPL can't compute physics for all AI, but it's very annoying that AI
can do impossible things. :o(

A common problem, which I'm afraid can only be solved (and yes, it can
be solved) by lots of practice.

I find it best to hold the revs steady near the redline, release the
clutch and ease of the gas slightly at the green flag, and then put
the power back on with some throttle. As soon as the car begins to
slide to the side, decrease the power. As soon as the tires grip
again, increase the power.

The most important thing is to learn the way the wheels sound as
they're spinning. Soon you'll be able to know exactly when to ease off
and when to speed up just by listening to a wheel spin, as I do

The Honda (murasama) is the hardest to get off the line quickly.  I found
it needs to be revved high and once you engage first, be gentle and build
to full throttle.  I like to start from the back of the grid and can
usually pick up places on the start and get blown off the track within a
few laps.  Practice helps!

one of your problems is in using the murasama/honda.
It seems to bog down a lot more than any other car.
It is one of the few cars where its actually hard to get wheelspin in 1st.
you really have to rev it and dump the clutch.
in the lotus and most others just revving it in first will do it even if you
are moving already.

also i think using the clutch is overrated.
even with all aids off, GPL gives you a kind of autoclutch for starts
anyway. Even if you use a manual clutch its still there.
I just hold the revs at around 7000 rpm or so (depends on gearing and car)
when the flag goes down i slam it into first, the compensate with the
throttle to keep the revs up and wheelspin to a minimum (a small amount of
wheelspin for a second or too is just about right). I always beat the AI
this way, and all my mates aswell.

I see. I squeeze the thottle hard with clutch on and when the green flag comes
down, I release the clutch. I usually find myself starting earlier than the AI
cars. Is it "cheating"?

Griffin.

that's right, but you loose about half a second or more, because there
is a delay between the pressing of the shift-button and the actual
shifting.

So don't shift. Put it in gear and sit there with the engine idling.
The brakes will hold the car automatically until you hit the gas. When
you do, you get a brief clutch effect, and the revs shoot up. You then
can modulate the throttle. Try it sometime. It works well in every car
except the BRM.

well its definately NOT half a second. anyway what about the delay in
activating the clutch(digital or analogue)

Put the car in gear before the green flag...

I'm using a button for the clutch (till my home made peds are ready).
I put the car in 1st gear, rev the engine up to 5000rpm or so, and when the
flag goes down I release the clutch and slam the throttle at the same time.
Back off the throttle a little before the wheels start spinning and  I'm off
the line fast and easy (mostly...)
