I've recently come into some money and am trying to figure which path to take as a megasquirt controller. I've read the manual and only questions several times but to no avail am having trouble trying to figure out what I want to do. For starters I have a L28e that I turbocharged from a 77 280z. The only thing I'm looking to do is controll my fuel and spark and be able to tune properly somewhere in the neighborhood of around 15-18lbs of boost. I'm just trying to figure which version my money will be best spent in and is the most user friendly. I work for CarQuest so oem parts aren't incredibly hard to come by and I have a budget of around 500$-700$ if I can get any input from current users about their systems it would be much appreciated thank you.
