All I did was take the wiring from the Logitech pedals and run them to the
same terminals on the 250k pots that are mounted in the TSW pedals.  The
pots for the Momo's are 10k I think.  So there is a huge difference already.
I didn't change anything else.  The direction of the pot rotation is
opposite on the TSW pedals also - but none of that made a difference!  GPL,
N4, NR2002 and RT all work!  GPL ROCKS with my clutch.  Yikes, just what I
needed something else to make it harder <g>  Oh yeah, the clutch stays on
the USB adapter (purchased from TE) as it's own controller and works fine.

You gotta get the Momo pedal pads from TE if you do this.  They look SWEET -
especially with the Logitech Momo wheel.

Wouldn't it be simpler to take the pots & the wiring from the *Momo* pedals
and install the whole shebang in the TSW pedal base?  That way, you know
you've got the right pot values (and, presumably, rotation), so the rig
oughtta work with non-U games like Rally Championship.

Great tip abt. using the Momo pedal pads with the TSW gear--yer right, the
stock TSW part looks like it came from a 1978 Plymouth Scamp; the Momo pads
oughtta look a lot more convincing.

Hi David:

Did you have any problem using the 250K pots from the TSW as opposed
to the 10K pots that come with the Momo?  I did the same thing as you
with the pedal unit from my TSW, just moved the Momo wiring over to
the TSW pedals and hooked them up to the pots.  The pots that were in
my TSW were 100K's, and I just couldn't get them to perfom with the
Momo.  In F1 2001, I couldn't hardly get any acceleration, even with
the throttle fully depressed.  I finally gave up and stuck the 10K
Momo pots into my TSW pedals, hooked them up, and everything was fine.
It's weird, cause I was using the 100K pots in the TSW pedals with my
old LWFF and everything was fine, but not so with the Momo.  With the
10K pots, I now find throttle and brake to be a lot more sensitive.
I'm assuming (and I'm by no means an expert in this area!), that the
sensitivity is caused by the fact that I've now got a range of 0-10K
over the same pedal travel as I had before when I had a range of
0-100K.  Does this make any sense?  I'd love to be able to get 100K
(or better) pots working with the Momo and TSW pedals.  

Ian

That's exactly what I did, moved the whole thing, wires and pots from
the Momo to the TSW pedals.  As I mentioned in my previous follow-up
to David's post, I'm finding the 10K Momo pots to be quite sensitive
as compared to the 100K (or higher) pots from the TSW.  The problem
is, I can't get the 100K pots to work, so I've defaulted back to the
Momo 10K pots and everything is fine.  Do you, or anyone else, know if
using higher value pots will permit less sensitivity, and most
important, how to get them to work with the Momo in F1 2001.

Ian

One more thing David.  When I was attempting to use the Momo with the
100K pots, I seem to recall that they worked with N4 and GPL, since
they have in-game calibration routines and I was able to calibrate
within the sims.  The main problem I was having was in F1 2001 (which
doesn't have an in-game calibration), and since F1 2001 was my
preferred sim at the time I was mucking around with it, that's why I
had to revert back to the 10Ks.  I noticed that you mention N4,
NR2002, and GPL.  Would you happen to have tried the higher value pots
in F1 2001?  I haven't got RT in Canada yet, but I'm glad to hear that
it works.  When I get tired of F1 2001, I'll probably revisit the
issue and try again.

Ian

Ian,

AKAIK, the Momo pots are 50K, not 10, but I could be wrong.  Whatever they
are, they have to match the value in the appropriate Registry key.  IOW, you
have to edit the Reg so that you get a range of 0-256 to show up during the
N2002 (and GPL, I think) brake & accel calibration.

F1 2001 is a separate prob.  Their calib routine sux, to be charitable.
Since it would be tiresome to re-edit the Reg every time you switched games,
the only other solution would be an external trimmer pot (in parallel, I'd
think, but mebbe in series--dyslexia is messing with my head ATM) that you
could reach from your racing, ah,***pit.  Or you *might* be able to
accomplish something with a controller applet like DXTweak or ProPanel.

I'm not fluent in Hex, so maybe somebody else could suggest the appropriate
Reg values for 10, 50, 100, 150, and/or 250K pots.

--Steve

Initially that was my plan - to wire the Logitech pots to my TSW pedals -
but they wouldn't fit too easilly.  Plus there was no easy way to rig the
arms from the pedals to the pots that could see so I decided to take the
chance and use the TE pots.  Guess I was lucky because it worked pretty damn
good.  In the Wingman control panel both pedals are backwards and the gas
only travels half way, but in all the games I play that doesn't make a
difference because they either have their own controller setup or an ini
file to edit so that I can make it right.

- David

Hmmm.  Not sure about the difference between the 100k's and the 250k's.  I
assumed all the TE stuff was using either the DK 250k pots or the SPEC pots
which I'm just now reading are only 50k ohms.  In any case the 250's are
cheap at $12 each and the fit perfectly on to the TSW rig.

Not sure about the controller setup in F1-2001.  It doesn't seem to good to
me.  I had an easier time getting my stuff to work in GP3.  I always use GPL
and N4 as my test areas for controllers.  Papy oughta license those modules
and make some money as well as save our community a lot of headaches in the
process.

Heh.  I know absolutey nothing about potentiometers other than the fact that
my Fluke multimeter can measure the amount of resistance in ohms at
different spots in the rotation of the "wiper" (I think that's what it's
called).  I'll fool around with F1-2001 some more tonight and get back to
you with my results.

Just went in to F1-2001 (GT Mod v2) and got everything to work!  The Momo
wheel wired to my TSW pedals and even the clutch.  Click here
http://www.flexbon.com/tmp/dc/f1-2001ctrl.jpg to see how my controller shook
out in the options screen with the 250k pots on the TSW2 pedals.

Sorry - I thought from Ian's post that the Logi pots were an easy fit.  I
guess the better alternative would be to find an exact (electrical)
replacement for the Logi pots that would fit the TSW...shouldn't be all
*that* difficult.  Then just resolder the wiring.

Now maybe somebody knows the specific resistance of the Momo pots?

--Steve

Thx a bunch for ResHack; I'd never seen that one before.  Sounds as powerful
(and dangerous) as a 10mm Sig auto-loader.  I'll use it sparingly.

--Steve

Oops, sorry, I should have mentioned that it took a bit of
"creativity" to get the Momo pots into the TSW pedals.  I ended up
using a tightly fitting *** grommet around the shaft to hold the
pots in place along with a couple of small clamps.  Not the most
elegant solution, but it'll work till I get some new exact-fit pots.

As for the specific resistance of the Momo pots, the markings on mine
say "10158-0000 10K/30 0127".  I assume that the 10K refers to the
resistance, but have no idea what the other numbers mean.  If you come
up with a source for replacement pots that will fit the TSW, please
let me know.

Thanks,

Ian
