Modern Vespa

Regarding the voltage regulator, is there a more reliable alternative than the original Piaggio/?¥

I use japan motorcycle voltage regulatot for my vespa s 150 3v. U just need to know what your type (3phase or fullwave), then find the subtitution. There are more cheaper, but dont buy the imitation.

Hi, a little old post, but maybe someone can help me here.

In mine MP3 500 the ECU is attached to the throttle body and I check the stamp and say IAWRIU2.E05 is this one compatible with IAWDiag or JPDiag before I start to purchase cables and try to play with? In the list of ECUs in IAWDiag I can't see something that say me is this one...

Thanks a lot for the help

Sorry to say but only the "old" MIU1 and MIU3G ECU's are supported by the diagnose programs JPdiag and IAWdiag.

The changelog for IAWdiag does say that it supports several of the IAW series not just MIU. (I'm not saying if it does it doesn't work with dariusz's IAW)

I expect something like that

Thanks for the answers

Hi everyone,

in first thx Pilaf for the infos, great job.
Its working on my Piaggio Mp3 400ie.
When I start the engine, 4-5 sec after stop it. The fuel pump, ignition, injection are ok.
When I running IAWdiag, no fault codes, just I realised the intake manifold pressure value is 0, but its not able zero, because when the engine run, there it is a vacuum.
Where the ecu measure this?

Thank You
Rob

Is the software capable of dislaying LAMBDA value for analysis while riding the bike?
This is not about fixing a small laptop to the bike. Before I think of that I'd need to know if the KK line is fast enough to show accurate lambda values.

I have a 2011 300 GTS that I bought used a couple of years ago.
When I bought it the engine was not running. Several people had tried to repair it, but did't get it run again. The last owner did buy a used Throttle body from eBay. I got it to run after short time, the registers chain was not at right place.
The scooter has been running after this almost normal. I have some issues at startup when it's "cold". I wonder if some of the last owners tried to adjust "idle screw"
So my question is easy, will I be able to read with this cables and software what degree the TPS is and what is should have been?

The software will show you the degrees open throttle. During idle this is 3.8°.
It will just report what the sensor "sees" though.

Had a request for .bin files, uploading here.

Thank you!!
