you can get the software free..... and the e-manage hauls the SAFC any day of the week you just have to know what your doing, they both do the same things but the e-manage does everything a SAFC does and then some more. Just to name a few that I'm pretty sure an SAFC can't do are, Timing adjustments, Have a boost input and tune off of that (even more so with Ultimate), Full logging capabilities, and more control over what the ecu sees and does Hell you can use the second MAF input to log a wideband too. I know without a PC (or E0-1) you can't tune it but it has so many more things on it. IMO E-manage blows away the SAFC and since you already have one your golden, I bet you could pick up a cheep laptop for like $150 to use only for tuning too, that or have a shop tune it. anyways the software can be had "If you lost your disk" @
http://groups.yahoo.com/group/emanage/ this place is a great source of info for the E-manage, there are all sorts of tips and tricks just waiting for you to find em. Seriously Keep the e-manage you will not be sorry once you know how to use it and can take full advantage of all the radical stuff it has. Peace, Pat
