What is the Profec A

[gtst4d]

I know they are a boost controllers, but what is the difference between the profect a and profec b boost controllers, did a search on them and found plenty of people using profec b's but couldnt find any pros or cons on the profect a, any help would be greatly aprecaited

ProfecA has more options, I think a more advanced fuzzy logic chip in there to control boost. It's also correspondingly harder to setup as it has more options (which may or may not be useful anyhow).

Most people go for the profecB because of the simplicity of it.. and most report pretty good results.
