Greddy E-manage - Whats The Go ?

[Sammy]

hey guys

i am at the stage where i need to sort some sort of management for my RB20 silvia.

Now i have been doing a bit of reading around the web, trying to see how the Emanage has worked on cars similar to mine as not many people seem to run them here.

However with Greddy recently launching the Greddy E-Manage Ultimate - it is now a high contender on my mind.

So my question is:

why would you use a power fc/microtech over a GreddyE-manage if it can do ignition, fuel maps, air flow meter changes etc with the emanage?

if anyone has had experience with them, pls post up!!!!!

thanks
