Modern Vespa

Hi, I've been searching for the past hours, mainly if my engine is et4 or et2.
I want to be sure about the specs of my scooter before buying a Malossi cdi.
Here's the identification for my scooter:

VIN: ZAPC536B
model: Vespa Primavera 50 4T 4V

The problem is:
Malossi Injtronic is for 3V scooters only, for et4 engine.

However, Malossi Digitronic is for 4V but it's specified for et2 engine.

What I can't figure out is wether I've got an et2 or et4 engine(and if it matters)!

Thank you for your help

Interested about this as well, can't figure out which CDI I need and have the same Vespa as yours.

This is the one you need

Neither. You can search for the remainder of 2024 and aren't going to find out your engine is et2 or et4. Those are both much earlier Vespa models, neither of which use this CDI. This Malossi CDI is for four stroke, four valve 50cc LX, S, Primavera and Sprint models with a carburetor. Does your Primavera have a carburetor? If so, 5514396 is the correct part for you. If your scooter is fuel injected, this is not the correct part for you. If you are unsure if your scooter is fuel injected or carbureted, it would be a good idea to find out before ordering one of these.

Scotty would be proud?

He's more an extrapolation kinda guy.
