I'm guessing firmware version 2.5 is what you want. The later versions are for CAN vehicles (like BMW bikes). I don't know if that means they won't work on non-CAN vehicles or only that they're CAN compatible.
BTW Sam, are you using the stock fan on the new radiator? I'd like to find a better fan. In higher temperatures the stock fan really struggles to bring the temps down from 218. Today in 80 degree ambient temps I was seeing 222-224 before the fan started to slowly bring it back to around 215.
I'm guessing a better fan would help but it may be that there's just no room between the fan and engine block and thus nowhere for the air to go. Unlike the sides which are relatively open.
