Ducati 620 Immobilizer removal through TUNEECU?

Hey guys, I'm new around here and I just bought a project bike that the previous owner lost the keys to, a 2003 Ducati 620 Dark. I got a great deal so I figured worst case scenario I can swap it to Carb or part it out, but I'm a pretty handy guy and would like to remove the immobi from the ECU through a new map and bring this thing back to life!

So far a bunch of people say this is possible, and obviously it is if there are companies offering the service (for $250), but my google fu is not good enough to find EXACTLY the method I need to go about this. I ordered the necessary OBD and USB cables and downloaded the correct drivers, I think.

What next? Should I use DucatiDiag, TuneECU, Guzzi(something)? I put another ignition switch/key set into the bike that a friend had laying around and now the bike turns on, but obviously the immobi is preventing it from cranking.

Thanks so much in advance, and if anyone needs proof that this bike is not stolen before offering advice, I will gladly provide pics of the title as well as the folder of service records from the P.O.


ETA: Thread is worthless without pics, right?

You will need to find an "XDF" file for that bike. With the appropriate XDF loaded into TunerPro you should be able to turn off the immobilizer. I have never worked on one of those so I am only guessing based on the ECU files that I have seen. You will also need Guzzdiag to read and write to the ECU.

Awesome thanks for the info. Is an XDF the same as an HEX file? I found a map for my bike in the hex format. If not, what is an XDF file and what does it do?

Sorry for the noob questions. This is my first Ducati/immobi problem.

Another question: I downloaded GuzziDiag, but when it asks me to pick which bike I have, which one would be compatible with my 620?

For about $250 either Houston Superbikes or MotoWheels can reflash your ECU with a DP performance map (if available) and also remove the immobilizer. But you need to call them first because your dash could be linked to the ECU.

Jerry,
iaw5x (reader & writer) will do the 59 ECU. I have not used it on my 998 because I do not have a working XDF :(

I believe you will find that you have a 5.9 ECU There is software that can read and write to that ECU but the "Editing" part is where it gets tricky. An XDF file is a "translator interface" used by TunerPro to decode and edit your BIN file which is your map. Now if you have a HEX file and you are able to write that to your ECU using TuneECU that may work as well. I would pursue the HEX file first, I am not aware of any XDF files for the 5.9ecu but I have not looked for one. TuneECU uses HEX and TunerPro uses BIN.

Hope that helps.

Post (attach) the HEX file that you have and I'll see if I can read it. Add.txt to the end so that it will upload.

Don't forget to order a "Fiat 3 pin to ODB2" cable

I loaded up the above xdf and bin files, it looks like that is what you need.

Its not very difficult at all. As said earlier you need an OBD cable. I use a VAG. Then you need the fiat adaptor. IAW5X reader and writer. An XDF for the bike and tunerpro. Pull the map with IAW5X reader. Disabled the immo with tunerpro using the XDF. Upload it to the ECU with the IAW5X writer.

Its that simple. It might however be a bit fiddly and difficult the first time before you find your ways around the softwares but if i could learn can everyone can learn.?

And this

I spoke to a member of one of the big name Duc tuning shops and he basically balked at me when I told him I was attempting this myself. He told me that my model specifically would still be bricked even if I did the ECU reflash because of the immobilizer in the dash. He said it would only run with the dash removed. Is this true?

Not true. I have been disabeling the immo on a few 2;nd hand ECUs that i have been buying on ebay. I have been using ducatidiag flasher for 59m and guzzidiag flasher for 5am. The reason i used ducatidiag was that at this time guzzidiag did not work on 59m. Today it does.

Works good.

A minute or so.

Make a backup of the original file, before messing with the ecu.
Do not switch polarities on the battery with the cables, will fry your ecu.
Do not use the blue-tooth option to flash your ecu.
Check if your cables actual work, 'cause 99% of the time the cables are the culprit.

This and your bad ECU post.

I seriously doubt your ECU is bad. If the bike runs, then your ECU is 99.9999% for sure OK.

Everything I have read about connection problems points to the chip.
The FTDI 232 chip is known to work. I have two Lonelec cable kits and both work out of the box after installing the correct drivers, which as vij wrote must be installed before connecting the cable/adapter so Windows does not make the driver choice.

I have read, but not paid too much attention to it as I have the correct chip/adaptor, that it may be possible to make things work by connecting a couple of pins together.
You will need to search for info, but I also recall the LED colour is an indicator of the chip inside. Mine is red and I think/recall blue is :bad"

You could contact forum member jduke who is in Savannah GA as Jerry has a kit that we know works.

Given the price you paid, compared to the Lonelec kit I have and the cut down CHIPI-X I have for the LC-1 WBO2 connection, I think what you have bought is likely to be wrong.
We all do it, but sometimes it is worth spending a bit more to save the angst.

With the cable connected to your computer you could also drill down via control panel, hardware, then printers and faxes I think, then look at the USB serial converter properties to eventually look to see what driver is in use to see what you have.
I am a Mac user for some 8 years and thankfully have forgotten all the details of how Windows "works"

You might want to head over to the Tech forum Datalogging and mapping thread to look at post # 177 I think, where you will find my guide on this and other matters,

The whole event of getting your bike and pc connected is flakey. There are many things that can and will fight you. This headache is not unique to you ;) Keep pressing buttons and flipping switches, you'll get there. If it were easy everyone would do it.

Post the Bin file here that you read from your ECU. add ".txt" to the end. I'll see if I can remove the immo for you using TunerPro that way you can upload the exact map.

when you read the ECU file a info file is created, you posted that file. I posted the txt from the file you posted. I am a bit concerned that your ECU is a 5.9 and the m620_mr_harry_version.bin shows it is a 5a ECU.
