Okay, I'll pretend it is just like analog distributors.
I think that you can. There is a plug in the base that you unscrew with an Allen wrench to access the switch. You will need good light and eyesight or a magnifying glass to set the switch.so I don't recall if I can change the curve with the bracket attached
Biba - the programmable one will have a USB port that you plug a standard USB cable into. You don't need a laptop per se, but you need a computer that is close to your car or maybe a super long USB cable.Also my first read of the instructions indicates I need a PC laptop to set it up. How this works with the wires that come with the distributor is beyond me (and I don't have a PC laptop), but Max at Alfaholics programmed in their own special program, in addition to the ones that come with it.
