I auto-guided my 9.25" Evo. Wifi was too flaky running PHD2 and Planetarium software over the link at the same time using NexRemote. I had to switch to the physical hand controller and a serial connection to the PC. (if you have less WiFi traffic in your area it may work better but building a cable is not hard or costly and will save you frustration in my opinion).
Guiding was okay but the Evo mount is underpowered and just a little wind would wreck havoc. I should also caveat that I made my own wedge. I could not get it closer than a few arc-minutes from the pole.
Even autoguiding, I think you will be stuck with relative short exposures and you will have a fair number of exposures you will have to drop due to tracking.
You may want to post this question to the Celestron forum under "Telescope Specific Forum." There are a couple of users there that have discussed this issue.
FYI, my best session with my EVO mount and autoguiding:
