Who cares? It is completely inferior to the almighty DSMlink. Sure link is more, but the SAFC is solely fuel... DSMlink does that, ignition control, no lift to shift, two step, antilag, and a host of other really cool shit. If you want to compare features, DSMlinks site is
www.dsmlink.com and I am sure you can find the one for SAFC by searching "Apex industries" on google.
