Schwinn MPower Echelon2 users

Hello

Sorry if this is in the wrong place - I’d be grateful for any users using a Schwinn spin bike and their echelon2 console for any advice. I want to know if I need to purchase the echelon2 power upgrade, or whether the basic echelon2 without the power upgrade will work with Zwift. The Zwift site only says “mpower echelon2”, so I assume the power upgrade is not needed. I’d also be grateful for any updates regarding how well it works with Zwift. A few of the older threads notes regular drop outs but these threads are quite old now.

Many thanks!
