I would like it to be affordable, relatively simple to use for what I need it for and to run on either my garage computer (linux) or an adroid handheld device.
The ECU is located underneath the battery on the left side of the bike and usually has a sticker on it (w/ a barcode) indicating which ECU it is. In many case there is another sticker placed over this one that can be peeled off. The 848 Evo usually has a Magnetti Marelli 5AM ECU.
Here is the text from my ECU sticker [PIC]:
|IAW.5AM.GE BC.0098058.A||SA0PD004 (USA)|
|1098 08 ECU DUCATI055|
|Physical Connection||Fiat/Lancia/Alfa EOBD adaptor ($9.95) lead (must have the +ve and -ve battery connection leads), see connection diagram at below. Koolertron F-12 ELM 327 OBDII bluetooth OBDII adapter ($10.20)|
|Standard||KWP2000, ISO 14230-4|
|Startup sequence||auto-reply to the ECU on power up a certain ISO hex code (55 B0 80 80 80 85) at a specific timing interval|
|Scan M5x Monitor|
|Scan M5x Tools|
|Test Pompe Essence||->||Test Fuel Pump|
|Bobine Verticale/Horizontale||->||Vertical/Horizontal Coil|
|Injecteur 1/2||->||Injector 1/2|
|Ventilateur M59/M5A||->||Blower M59/M5A|
There's a few data points in Scan M5x Monitor that I'm unclear as to their meaning:
|Scan M5x Monitor|
|Pressure||1010||Intake? MAP? Exhaust? Fuel? Probably Fuel (kPa) or MAP (grams/sec)|
|Air||21||Ambient/Intake/Exhaust Temp?(C) Air Fuel Ratio? Flow Rate? Probably ambient/intake in C (21C=70F)|
Plug the Fiat 3-Pin to OBDII Adapter into the loose connector below the ECU, connect the battery leads to the motorcycle's battery, plug the bluetooth OBDII adapter into the loose end of the Fiat adapter and fire up your diagnostic application
DucatiDiag had diagrams
to double check the fiat adapter wiring using the Fiat 3-Pin to OBDII Adapter
that are reproduced below.
Note: the pin outs are reversed on the OBDII picture if checking continuity with a meter on the cable itself. Diagram #2 was correct for my Fiat adapter.
