Modern Vespa

And on Digital Kaos I found a BIN for the GTS 300 HPE E4 CM291701 (2019/Feb/25). Note: I don't know if this is the stock bin or the one that the dealer uploads when the piaggio sports exhaust is installed.

On the Aprilia forum I found an XDF and BIN for the GTS 300 HPE (or GTV?) E5 CM316204 (2020/Aug/03)

My 2019 Supertech has a CM291706 so I modified the XDF from the E5 to work with the E4. Next step is for me to workout how to read/write the bin to my ecu as then I'll change the speed limiter (messing with the maps is beyond my skill).

Comparing the mappings between different scoots such as the MP3 300 HPE which has different power figures in it's specs sheet would be interesting. So if you have BINs for other MIUG4 scoots then let me know

And of course a big thanks to Meinolf and Bernd (of GuzziDiag fame) for sourcing the E5 and reverse engineering it

Important: GuzziDiag currently can't read/write the BINs. I will update this post when I know how.
XDF and BIN files for both are available at https://steelbytes.com/vespadocs/BINs%20and%20XDFs/

The torque map is the same in both. And bonus conversion to hp
