I'm in the process of tunning a universal efi kit I fitted to my RX3 (originally carburated here in Argentina). It's a chinese knock off losely based on the Microsquirt. I learned quite a few things… the one you mentioned being one of them. One (small, really) issue I'm having is that despite this chinese ECU being almost fully programable, it retards ignition on close throttle/coasting wich causes popping and backfires, no matter how much fuel I add or cut on the map for that situation, and that functionallity seems to be hard coded in the firmware and there is no parameter to set it (or disable it). But besides the race car blurb on deccel it Works great, so I've learing to live with it.
Just in case anybody is curious, this is the one I have:
