ECU availability

[thack]

I have a chance to buy about 1/2 of a Paso 750. The engine/frame/swingarm and rear wheel. No electronics come with the bike. How hard is it to find an ECU? Can I just wait it out on eBay?

The bike doesn't have an ECU, it has a dual ignition system consisting of the pickup, ignition module, coil, wire, and plug. You can find everything you could possibly need on eBay, as there are a couple of guys who seem to be consistantly buying complete bikes and parting them out.

what do the ECU connectors look like ? If there are 2 it`s a Kokusan, it`s only one it`s a Digiplex.
And pls. add your location to your profile, thx.

EITHER way there is the IGNITECH TCIP4 alternative which is MUCH cheaper, RELIABLE and PROGRAMMABLE. 110 EUROS, 150US$ plus shipping.

The Ignitech Module is "PIN to PIN" directly swappable with the KOKUSAN modules;

As for the DIGIPLEX (very uncommon on the PASO750) I think you will need to replace the single Digiplex Pickup with the double version used with the KoKusan modules, I am not sure if you also need to replace the flywheel, in any case both items are available for little money on Ebay.

here is the link to the Ingnitech Website (plenty of info in cyberspace) http://www.ignitech.cz/english/aindex.htm and if you go for it, just make sure you ask for the DUCATI "specific" Version.

In the US there was an online shop selling them, http://www.CA-Cycleworks.com, the owner, Chris Kelly posted several contributions on the net but I am not sure if they still sell them.

in anycase, I have purchased directly from the manufacturer, they stand behind their product in case of any issues and they are very professional.

I Fitted it to my SS750 Special (highly tuned engine) and really makes a difference, in particular with HC pistons.

very uncommon on the PASO750

If I remember well the bikes intended for California had it. I know of 3 Pasos here in Europe who have it and all three were imported. Jon also had one and some other guys in the forum, too. But I agree most had the Kokusan units.

Is the Ignitech a plug and play with the correct settings for a 750 Duc ? I`m just asking as there`re lots of guys here that do know little to nothing about CDI programming or electrics in general

I was lucky to find a complete wiring harness once from a Monster/Supersport for €25 and the CDIs came with it
If it`s a private seller it`s always worth giving the pictures a better look.

There`s currently a programmable Digiplex replacement on ebay (works on 750 & 900, normal or dual spark heads). No need to change anything on the engine with this - IF you have a Digiplex not Kokusan CDIs.

I recall the Digiplex being used when the 906 came out as both bikes had the same "set-up", in EU the only bikes i saw with the Magneti Marelli Unit were RE-imports from the USA in fact they had the US BRAKE light unit (all red) instead of the EU version. The one had a very late VIN # therefore I guess the MM unit was used towards the endo of the life of the 750 Model.

As far as the IGNITECH uniti is concerned, they will supply:
- Unit (DUCATI version)
- dedicated wiring loom for KoKusan Modules
- CD Rom with .EXE file (downloadable from their web site too)
- Instructions.

I recall mine came with a starting map in it, then I actually made my maps either by copying the PEDERZINI Modules maps, the OEM version and my own "experiments"

The fitting is straight forward, remove modules, connect the proivided wiring loom, turn the key and in theory it should start straight away provided the map comes preinstalled.

it is absolutely a no brainer and you can find a lot of info online, including a nice set of experiments carried out by BRAD BLACK (www.bikeboy.org) who explainsd very well what are the limits and what can you actually play with.

Its a well made unit, small and light and has also extra features like RPM limiter, Shiftlight and could me linked to a TPS in order to have different maps

it`s only one it`s a Digiplex.

I forgot about the Digiplex - since my 750 doesn't have one.

I wonder just how much of the electronics the partial bike has. At first, I was thinking that the complete wiring harnass and all components were gone.

[thack]

The only electronics it has are what is bolted to the motor. No harness, no module. It does have the coils. I've since found a module on ebay and harneses are available there too. Thanks for the wealth of information. I'm going to go get it. I can't go wrong with the wealth of knowledge here!

Are you saying you used a modern Monster CDI on your Paso?

all SS and Monster 600-750 and some 900s WITH CARBURATORS have the KOKUSAN ingnition modules.

There are two Kokusan modules or one Digiplex. Be sure what you buy is what you need.
Can you make a picture of the wires and connectors that come out of the front of the left engine cover? Otherwise the only way to be sure you get the right parts is to remove the alternator cover to make a picture of the flywheel as that looks different between the two ignition systems.

The Kokusan ignition modules have the number BB1105. They are the same also on the Cagiva Elefant.

PS: here`s a wiring loom for the Digiplex. I`m not posting this because I think this is what you need but because it´s difficult to find in case it is. Note most wiring looms seem to miss the front/headlight wiring.
Also look close at wiring looms you want to buy. Ie this one below was altered. The fuse holder in the front is not original.

angelix do you have the maps from the Pederzini modules and if so from which ones ?

Of course!!!!!!
I have them mapped and ready to go in my Ignitech ECU.

I have also the details of EACH of the 3 modules which are basically the DUCATI PERFORMANCE modules coded as
AL9000-1.1
AL9000-2.4
AL9000-3.0

They differ basically in the the advance curve

-AL9000 1.1 is suggested for for light tuning
from 0 to 1600rpm the ADV is set at 6 degrees
from 1600 rpm to 2800rpm increases from 6 to 30 degrees
from 2800 rpm to 8000 remains at 30 degrees
from 8000 up to 11000rpm goes down to 20 degrees where it remains.

-AL9000 2.4 is suggested for heavy tuning and low RPM torque
from 0 to 2000rpm the ADV is set at 0 degrees (Zero)
from 2000 to 3500rpm it goes from 0 to 30 degrees
3500 to 8500 rpm stays at 30 degrees
from 8500 up to 10800rpm it goes down to 11 degrees where it remains

AL9000 3.0 is for heavy tuning and torque at high RPMs
from 0 to 1800rpm the ADV is set at 6 degrees
from 1800 to 3000rpm increases from 6 to 34 degrees
from 3000 to 9000rpm decreases from 34 to 32 degrees
from 9000 up to 10500rpm goes down to 28 degrees where it remains



There is only one thing that is NOT very clear to me and I will need to do some investigation once I find some time:

- the way the FLYWHEEL is made it has a SET TRIGGER which is fixed (32-36 degrees according to the type of flywheel) and can be modified only by modifying the flywheel by making the trigger longer (refer to : http://www.bikeboy.org/ducati2vignition.html )

- The standard ignition modules are set up with a starting ignition advance (base advance csetting) which can be modified by moving the position of the pickups back and forwards and this will influence also the MAX advance as this is SET by the flywheel.

- I assume that with the modules starting at 6 DEG from 0 to xxx RPMs , the base advance (position of the pickups) has to be set at 6 Degrees; with the module starting at 0 (zero) degrees the base advance has to be set at 0 (zero) degrees.

Unfortunately I do not have the instructions for the modules, so I cannot be 100% sure of how the base advance has to be set.

With the Ignitech you have only to set the BASE ADVANCE SETTING, then enter this value in the software and after that you can modify in any way you like the advance curve bearing in mind the limits set by the flywheel trigger lenght; if you want to have more than the standard 32-36 degrees you will need to modify the flywheel.

[Tamburinifan]

On bikes w Kokusan from factory the idle advance is marked on the flywheel,
if that helps...
