The basemap is ok. It is not ideal for a 125cc engine as I think it was originally designed for 50cc engines. I ended up using the megasquirt basemap generator online for my VE and ignition tables. As for knock, you would need a genuine ms3 to do it right. I am running a ms3x with the dual knock board in my drift car and it works great. Problem is a ms3x would be way overkill for a single cylinder engine and would add about $600 to the cost. I plan on just slowing turning up the timing until I can hear knock, then back it off like 2 degrees. The great thing about these chineese bikes is everything is dirt cheap, so if I kill a piston its only like $30 and a few hours time.
