Easy to install and configure, and just works
Fitted my 1750 Alfa engine with no problems, and was easy to set up with a suitable ignition curve and then test and adjust to find the optimum.
Feels well made and robust, software seems to work well, although has a few slight oddities with the UI.
I would have preferred a Type B USB socket (often used on printers) rather than the micro-USB used. The micro-usb can be a little tricky to plug in inside a cramped engine bay, especially when the engine is hot!
Also, it would be great to have the socket mounted into the distributor body itself, rather than on the PCB inside. I think connecting the cable would be slightly easier, and it would be possible to leave it connected. With the current design, when connected there's a gap around the plug that could allow oil and dust to get inside.
