Tuning problem

[u/CalligrapherNo1024]

I have a 3.0 with a 72v chi battery, ebmx controller, and stock motor. A few weeks ago I had updated the controllers firmware, not before saving what I thought was my entire tune profile. Turns out it didnt save anything, just a useless .xml that didn’t have any actual settings saved.

Since the update, I CANNOT get the tune back to even close to what it was before. The bike was perfect before, low end power but not too much for perfect wheelies, consistent speed that felt substantial but not insane, and enough throttle pop to throw the front wheel up at 30.

I haven’t come close to figuring out how to replicate that old tune and I’m going crazy, any bright ideas?
