For those that say carbs are easier to set up than fuel injection probably haven't experienced any of the new aftermarket EFI systems. My ProFlo4 (thanks Mike Bray) was super simple to set up. The software is an app on my phone, amd it connects via Bluetooth. All I had to tell it was my engine displacement, cam specs and firing order. Oh, and my intended fuel pressure. It loaded a base tune, and it fired right up first time. I was go-karting 10 minutes later. So simple.
