RD1 and RD2??????
the s-afc is a piggyback. it takes the voltage levels and changes them to "trick" the stock ECU. the standalone doesnt need to be hacked because it is fully adjustable where the stock ECU is not, which is why it needs to be tricked in the first place smile.gif

Ahh, so the SAFC IS a piggyback. I was under the assumption that the SAFC was a semi-standalone something-or-other. It's clear now.
