Ducati and MyP8
10/16/12 at 18:42:45
 
Hi all,

Just joined here and getting closer on putting a MyP8 to my ducati.

Is there anyone else here, that has put a MyP8 to a ducati?

The thing is that, unlike a Guzzi, the SPS has 2 injectors/cylinder and I'm just wondering if anyone has done the groundwork for this?  Wink

and, to make matters more complicated, I have understood that the injectors are fired sequentially, not at the same time. (the 996S ducati fires the at the same time, but that engine uses the WM16M ECU).

So, that's my introduction, greetings from Finland.

Wonder if there should be a limit how many grazy finns may registrate to this forum  Cheesy

Marko's 996SPS seems to use two sensors at the flywheel to sense the crank rpm and phase. Does the older Guzzis using P8 have similar setup ? This is addition to the double injectors seems to create certain challenge in putting MyECU to SPS.

We seem to be close of forming a local "MyECU drivers association" here in Finland. There are already at least 4 MyECU units here that I know of.

The pickups are the same on the Guzzi, so I think that can be sorted.

What I am worried about is the injectors.

but after some e-mail conversations with JuhaV and LOS, I think this can be handled.

The P8 is typically a sensor on the crank ( 4 lugs ) and a sensor on the cam ( single lug).
Two on the crank doesn't make sense.

Yes, that is true. One pickup is on the flywheel and the other on a different wheel, which rotates twice as fast if i remember correctly.

This is all just early stages. We'll be learning by doing along the way.

Next thing i need is a spare P8 box with the connector.
Then I'll be contacting you Cliff about the stuff that's needed inside.

There is also a miniMyP8 that fits into the 16M case

Yes, i know.

But if, and when, I find a reasonably priced spare P8, It will be much easier just to plug and play with the original housing, than to fabricate a place/fittings for the WM16 housing to go to my bike.

and, my plan is to use the current - fried - ecu for the MyP8 and find a new replacement-original, so that I have at least one working ecu on hand all the time.

So, how much for the MyP8 stuff, delivered to Finland?

I checked the schematics of the P8 ECU of a Guzzi and my SPS and as expected, the pin order is exactly the same on both.

I wasn't expecting there to be any differences, but just to be sure.

Of course, the ECU for the SPS has 2 more pins for the extra injectors.

the new ECU is here from Italy, and the bike starts/runs with it (balance/TPS/CO needs to be set.. if I want to use it..)

so the old ECU can now be cannibalised.

The P8 uses those external amplifier-thingies for the sparkplugs. Any advantage in skipping those and putting in for example coils that are built on the spark plug cap? Just a thought..

Here's a pic of the chip that was inside the new ECU.
...

I just took the old chip from the old ECU and put it in.
The old chip is the one provided by Ducati, to be used with the carbon-Termis.

Hi 996

Nice bike you have there. I've ridden a lot of ducatis including some 996's and have a old 900SS.

I think you should adjust the new P8 so the bike runs well. I think if you have a good base line it will be easier to sort the MyP8.

You are talking about COP, or coil on plug. There are also coils with inbuilt igniters.
http://www.efi-parts.co.uk/index.php?productID=238

I think at this point you should modify as litle as possible and when you have the bike running good, you can mess with it and try to improve it.

Modifying is just another thing to get confused if thing dont go well.

You are going to put the injectors in paralel? I think ducati used the P8 in the sps because of  injector duty cycle issues.

Cheers

Rick

I'm also thinking of using one of these coils in the future, the wasted spark one.

About the coils.. that's just an idea I'm throwing around. Definitely not doing it before I have the MyP8 working.

Funny thing, looking at the link and the site you provided.

It seems that the amplifiers that are on the SPS, are some sort of dual channel setups. but the thing has only 1 spark plug/cylinder?? I don't get it, but then again, maybe I don't need to...

this further proves to me that the Italians are in their own league, when designing and assembling motorcycles.. I used to have a Guzzi LM V.. comparing Guzzis (and nowadays Ducatis) at meetings and such, even if the bikes were of the same year, thay still had different parts among them.. go figure.. I guess they just picked the first part from the parts bin and thought, "this will fit.."

Cheers,
Marko

Do you not have a possibility to read out and compare the chips?

Yes I do, but not at home.

and then I would need to convert the HEX garbage into something more readable too, or not?

For a start look at Wayne Orwigs page, for instance. The web might come up with more  links to similar freewares, you need to search for it.

I used Wayne's ECUEDIT.EXE.

worked perfectly for my BIN file!

Thanks for the tip!
