I am planning to replace the MIU G3 ECU on a Vespa GTS300 scooter engine.
Single cylinder 300cc Four stroke with 24-2 crank trigger and stepper motor idle control.
Should I be using the 0.4.3c board or can I get away with NO2c board?
Also, any other advice would be much appreciated.
Many thanks,
Glynn

NO2C will work fine.

I've replaced the ECU in my MIU G3 throttle body with NO2c. The engine is running fine but I am unable to get the tickover below about 2000 rpm. I'm using the inbuilt stepper motor idle control but I'm unable to see what it's doing and suspect this is where the problem lies. How can I investigate this further ?
