please share your findings!

won't be overnight... 

kit 016-671 which is for a yamaha has the same throats and axial diameter as the ducati carbs.  it's for a trx850.  the TPS mount and boss is there and you just have to order the tps from yamaha (3 wire, i believe).  when ordering the kit from sudco, ask them to rejet it the same as the ducati carbs.  carbs are identical otherwise except the jets and the tps boss.

i think i need to pat myself on the back..

can the standard FCR41 be adorned with a TPS? What do you know, man?!

[junior varsity]

Here's what I know about TPS (Throttle Position Sensor) and the Keihin FCR series carbs:

021.561    1621-844 HARNES     $23.15
021.560    1614-812 SENSOR     $84.89

Don't know if is plug and play or not, this information found by researching on the Sudco website.

The TPS unit itself  is plug and play, but you have to wire it and program it in the ignitech.

That is as simple as wiring the TPS's wires to the proper plugs on the Ignitech harness.  Once it's connected, then you have to set up the Ignitech to understand the TPS's voltage range.  There will be a nominal voltage for a closed or "zero" state throttle and a maximum voltage for fully open or "one hundred" state.  Once you have those two values, you then set up the steps (10 available, just like the RPM advance) of spark retard.  I haven't done this yet except as a dry run on the desktop, but that's it in theory.

In short -- TPS has three wires, one is 12v (dropped to 5v usually) from the key switch for power and the other two are the feed to the spark control. ( It has a built-in VRM so variations in voltage do not affect it.  It works the same as any potentiometer. )

The output voltage usually is very low, such as 3.x to 4.x and increments in 100ths of a volt.  

You will have to use a multimeter to set the throttle positions to your needs -- i.e. write it all down.

you go first.  (and report back your doings)

As I've said in the ignitions thread, I'd like to give this a crack...I enquired about the TPS through a local distributor their price..
harness $35 aus
sensor   $139 aus       with a 3 week wait!

can an recommend somewhere to purchase in the states?

Time-out. Check my other thread on the TCIP4 right quick for the latest I got back from Sudco when I emailed 'em about it:

And more specifically:

Other information:

Those interested in getting a little more zip out of their bikes will likely find the Ignitech a handy ignition and performance tuning tool. The ignitech's features are not being fully realized in its plug-and-play form. The Ignitech's software shows the ability to use a Throttle Position Sensor (TPS). Those same people looking for more zip may also upgrade to Flatslides (such as FCR 41 for the 900 or the 39s for the 750). The Sudco catalog does list a TPS sensor and wiring harness:

021.561    1621-844 HARNES     $23.15
021.560    1614-812 SENSOR     $84.89


-- Email from Sudco re: FCR41s and the TPS --

Hello Josh,

Sudco Part number 016-671, the 41mm FCR carbs for the Yamaha TRX850 are basically the same as the Ducati FCR carbs. The biggest difference is the TRX850 carbs have the mount and throttle shaft for a TPS, where the Ducati carbs do not and these pieces are not available individually. The other difference is the TRX850 have longer spigots, different jetting and cable bracket then the Ducati, but all these pieces are available for purchase. Basically, if you purchased the 016-671 carbs, TPS from a 98 or earlier Yamaha TRX850, changed the jetting, spigots and bracket you would have Ducati FCR41 carbs with TPS.

that's funny... i emailed chad about a year ago about this and figured out the TRX carbs fit Ducatis and told him...

Chris was copied on the emails to Sudco, and here's his take on the matter:

You actually can't purchase the spigots for the Ducati dual FCRs. They're never available and are stupidly expensive. So the next question would be how much longer are the TRX spigots...


Alternatively, we have a customer who got FCRs + TPS working on his bike and he is reporting a huge improvement in driveability. I'm hoping he'll reply with some details of how he got it all to work.

Two shops that seems to sell spigots:

[monsta]

do you really need the spigots?  I would have thought that we could have just extended the throttle shaft, made a bracket to support the TPS and configure it from there??
I was just going to get the sensor and cable and see what could be done...

[ducatiz]

Yes.  The throttle shady is too short on the ducati carbs

Friends, Romans, Ducatisti,

I call your attention to this thread:

http://www.speedzilla.com/forums/general-ducati-chat/56146-ignitek-tcip4-amazing.html#post596784

Gents, we may soon have a package setup.

I am hoping it would consist of:

Vague instructions on how the wires connect to Ignitech
FCR 41's with tps connected, jetted to baseline ducati settings, with appropriate spigots, mounting, etc
More stickers to put on the back of my cage.

For those of you playing at home who already have flatslides, i'm not sure this would be all that helpful to you. But you may be able to sell those suckers and get the package. I'll annoy Chris tomorrow afternoon and post up any findings I have.
