JP has relaunched his free IAW5* JPDiag A licence is NOT required if your bike uses the IAW59M ECU (usually applies to 2001-2004 bikes). JP has generously set all this up free of charge. Please help keep things free and remember to donate. If you need help and advice then PM me.
Required 1. USB VagCom 409.1 KKL lead (the software will work with ELM327 and Galletto but KKL is preferred) 2. Fiat Adaptor 3. Cable Drivers 4. Software For the USB cable I recommend FTDI driver based ones. However, Winchiphead driver based ones will work after modification (PM me for details). The two leads can be distinguished by plugging in to the USB port. FTDI will not illuminate its LED, Winchiphead will illuminate its LED. The two fly lead Fiat Adaptor is preferred but the single (red) fly lead version will work. When you get your adaptor continuity test the fly lead. There have been instances of the wrong colours being put on the crocodile clips. The red fly lead must terminate at pin 16 on the OBD female plug. The black fly lead must terminate at either pin 4, pin 5 or both. Cable drivers can be found here FTDI (http://www.ftdichip.com/Drivers/CDM/CDM20830_Setup.exe) Winchiphead (CH341SER.EXE) Once the USB cable has been installed on your PC, identify the Com Port number for it in ‘Device Manager’ under Ports. A com port number of 1 to 9 is recommended. Use advanced settings to change the com port number if not. Software Download here JPDiag Bikes made between 2001 and 2004 are likely to have an IAW59M ECU. The correct setting for this ECU is ‘Slow Init’. This ECU does not require a licence for the diagnostic software to fully function. For bikes with the IAW5AM ECU use ‘Fast Init’ and a licence is required to fully function. Use the blue copy button in the software and then the request page on the website.

Teething problems If you already have a previous version then the cle.lic file will work with the new software version. As a temporary measure Software HitCounter Licence Request http://jpl250rs.perso.sfr.fr/jpdiag/jpdiag.php
It's the same as the previous version with no manufacturer affiliation. This is to reflect that it works with a number of manufacturers who all use the IAW* family of ECU's produced after 2001.
Chris other than having the hassle of getting to my ECU is there another way of confirming (maybe from the dash ) which model ECU it is. This may seem a silly question as model make i.e. 999 and year , or say models handbook , but I have had my ECU replaced (at Luigi Moto) as I'd fried mine , my replacement has US on the start up , obviously a yank job, but will it have to be the same code ECU or another possibility.
Only ways are to actually look at the labelling on the ECU or connect to diagnostic - Sorry Rule of thumb is 2001 - 2004 IAW59M. post 2004 IAW5AM, but an IAW5AM will work on an earlier bike. ECU changes like yours also add to the complication. The US can be changed from the dash. Assuming a 749/999
It's not an actual reading. Really it's just a start point. To correctly set the CO you need to use the trimmer with a gas analyser. Saying that, some have had success setting the correct CO by observing max RPM. Personally I use a Gunson Gas Analyser and one of these BSP TAPER THREAD x HOSE TAIL END CONNECTOR FITTING brass air water fuel bspt | eBay This allows the OEM gas take off points to be used.
Cheers Chris, was just asking as I just need the bike running to a level which isn't too rich/lean before it goes into the shop.
Hi Chris, I've found that 3.5-4.00 works fine on stock silencers and 4.00-4.5 for less restrictive, all taken at OEM points.
Hi Guys, I'm after a bit of help with the physical connection to the loom. I've bought the cables as per post #2, but the fiat adaptor seems to have the same connector as the bikes loom (749 2003). Has anyone else had this issue and is there an adaptor so I can connect. (Photo attached). Thanks, Matt
Wrong connector Look on the battery box, left side approx half way up There is a 3 way connector held with a rubber strap with a cover over the connections
I don't want to sound like a complete idiot, but here it goes! I've installed the driver "CDM20830.exe" and connected to the bike via the cables above. All seems fine. Did the cable test and get pings back 15/16ms and TEST 2 Ok. But when I connect on the main screen it just sits there saying "connecting", but never connects. I'm sure I read someone else having the same problem, but cannot find the solution for the life of me.
