Ducati
One for riding one for experimenting on…
Ow crap… something creeped in my head and i think the is no way of getting it out!
Yesterday i bought something to experiment on. Just a little thingy… Ow well, i might as well tell you i bought a second 916 with a 996 engine conversion (dual injectors and 996 ecu) with 136 hp.
But i bought it cheap, the owner sold it with one cylinder off and the bike not running. He thinks it’s a crankshaft bearing that went bad. The cylinder (in the box) looks like everything is ok. So to i’m taking her apart to learn and diagnose.
Time to buy me a Haynes workshop manual?
The thing that made me buy the 2nd Ducati 916 was this:
I think it would be fun to turbocharge a Ducati 916!
I read up on some ways of controlling boost other then letting it run on base boost. This looks like fun to buy!
Things to think about:
- compression is now 11.5, turbocharged compression should be lowered.
- Boost vs compression post. - where to place the turbocharger; under the oil cooler / front cylinder (just using exhaust gas from 0ne cylinder) ór under the seat (my butt can’t stand the heat / heat shield?).
- how to get enough oil and water to the turbocharger.
- intercooler? And if yes, where to put it.
It’s nice to have a project bike alongside my summertime fun bike. Best of both worlds!
I can’t wait until the sun begins to shine again!
0My 916 ecu read for the first time
Today i got a surprise visit from the mailman. Het brought me my free Moates T-shirt (and some toys to play with).
All items were packed separately in anti static bags and after unpacking all of them i decided it was time to open up the 916′s ecu to see if it would let met pull out the chip.
I needed to make a custom L-shaped tool as my fingers were to big to slide under the chip and pry it out. A bent small screwdriver ore something will let you pry it out from both ends and voila,… The socket is empty and the 28 pins chip is out.
The Moates Burn 2 and Ostrich 2.0 come with no documentation. So i have downloaded all i could find on the Moates website (usb drivers, manuals, tutorials, …). I found the information to be somewhat scatterd across the site. Some files are a bit old. But they will do the job.
With the Flash & Burn tool installed and the original 916 chip in the Burn 2 it’s time to try and read out the original chip. On my first few reads i got a 1k description file. Not the whole 64k binary. A bit of reading i found you have to enter the following data:
Chip addressing
Start address in Hex: 000000
End address in Hex: 00FFFF
Buffer addressing
Start address in Hex: 000000
End address in Hex: 00FFFF
The chip you select is the 27C512 (read only).
Then you “read chip” and “save buffer to file”. This will let you specify a file name and save the original read out.
Here is my original chip content: Ducati_916_G-ice_original_11022012.bin.
Next trick was opening the bin in TunerPro RT. The result was as baffling as when i opened a Saab non turbocharged bin file in TunerPro RT. There are so few maps! The maps are basically a fuel map, ignition map and some engine heating / air pressure maps. I think i need to go a bot deeper and look at the file with WINOLS and or a disassembler like IDA PRO to check if there are a few more maps to play with. But i’ve never used these, so i need to digg in to those first.
Aside the chip reader i have bought a chip emulator. This Moates Ostrich lets me hook it up to the Ducati in the original chip socket. When the Ostrich is connected the micro processor inside will pretend to be the original chip. However it will also (at the same time) hook up to TunerPro with a USB cable. When i change data in TunerPro the emulated chip data will change also. This way you can do some live tuning with the bike running.
It is however hard to ride the Ducati with a laptop on the bike, so what is the advantage i hear you shouting to the screen. You do not have to reflash a chip and click it in the ECU every time you do a little tweak. You can just hook it up, change the data and off you go for another test run.
Uploading data to the Ostrich was done in a few seconds with TunerPro. I clicked a socket booster (to ensure better data streams from the Ostrich to the ECU) in the original ECU socket. Hooked up the Ostrich and (after the drained -15 deg battery was charged again) started up the Ducati.
So far so good, no fuss, no setbacks, everything i hoped that would work just did!
The next step is to compare some 916 bin’s to my own bin to see what was altered for specific performance gains.
0Ducati original and tuned bin files to research
In my dwellings on the net i have found a few Ducati bin files downloaded by someone else.
They might be helpful to examine and compare maps before i attempt to take on my own bike.
To read and understand the files you need to load a description file. This one has been made by Desmo11, who in posting some findings, did a lot of the hard work for me!
Some stock bin files:
- Ducati 748 stock bin file.
- Ducati 916 stock bin file.
A tuning experiment:
- Ducati 916 bin file for a 52 mm half exhaust.
Treat the files with care, do not use them on your bike without proper feedback on the result. I advise you to at least have a wideband lambda on your bike when experimenting!
