I got the BIN file downloaded from my 2007 GTS 250ie, and unfortunately GuzziDiag's MIU1 XDF file isn't compatible (it's listed for a GTS 300 anyway). I was able to get ahold of a partially functioning XDF file though, and hope that this could be modified into something fully functioning.

See the attached for the BIN & XDF files.

I've made some progress in modifying the XDF file for my 2007 GTS 250. Comparing the working XDF file from a 300 (with the MIU1HW201 hardware), against my 250 (with the MIU1HW101 hardware) has shown that many tables have some or all values that are identical. I was able to then find the corresponding table in the 250's .BIN file, and create a partially functioning .XDF file. Many thanks to https://hexed.it, Excel's 'HEX2DEC' & 'DEC2HEX' functions, and a modernvespa forum member that PMed me their 300s' .BIN file.

See the attached for all fields that I have successfully mapped, and the corresponding .BIN (with software version 1224GA95) and .XDF files.

Now for the fun part: how the 250's tune (1224GA95) compares to the 300's (22A3GS14).

The description for each table is directly below the table in tiny italic font. I believe TPS % is the horizontal scale, while RPM is the vertical scale

Relatively small variations on the 300's fueling table, but the 250's ignition table doesn't even look like Piaggio tried below 3000 RPM. Also the ignition is WAY more advanced on the 300. I wonder if this is due to hardware changes other than the throttle body.

One more post for tonight. I would be interested if anyone else has any other software calibrations for the MIU1 ECUs. Post them here or send me a PM.

Awesome data, Thanks !!!
I am wondering if there is any chance you might have all the "Error/Fault Codes" for Piaggio/MP3 500 HPE Sport Advanced ???
Or maybe a link to dig into for myself, I have not been able to find more than about 26 which are listed in an old Service Manual ...

Not sure yet, have not picked it up yet, it's a 2021 MP3 500 HPE Sport Advanced, should it not have the most recent or newest ECU ??

I believe that's at least one generation ahead of the MIU3 ECUs. FWIW: the MIU1 ECU was only for a few years (2006-201?) and was replaced with the MIU1 ECUs. MIU1s have a metal side cover, MIU3s are plastic (at least on the Quasar motors, not sure about anything else).

Good day,

Your scooter is Euro 5, so it must have MIUG4 magnetti Marelli ECU and also Cable Euro 5 OBD2. So, a different connection (we have Fiat type OBD1)

Right now - as much as i know - there is no free software to read this ECU.

If anyone has any news about this matter let me know, because the MIUG4 ECU goes to new Vespa 300 HPE.
