Which is better and why?

 

i have a safc-2 but it doesn't seem to work right at the moment... it has a cool looking screen though

 

i have ansafc2 also but am thinkin gof going to the emanage, just trying to get some pros and cons

 

The SAFC is just a air/fuel controller, where the emanage has the adaptability(read purchasing more parts) to act as more of a stand alone management system. Such as real time mapping, larger injectors, boost cut etc. www.greddy.com explains it fairly well. There are a couple of 5th gen's with emanage on their VQ35's. Greddy is using it as the sole tuning of their Twin Turbo 350z kit.
