I got a HKS FCON piggybacking my ecu on my 93 turbo

. Is it possible to also put in the APEXi SAFC-II at the same time since they both adjust the fuel ratios? Much appreciated for any information.

if they both adjust fuel ratios and mapping, then why have both? dont waste your money.

Well the Piggyback can only be adjusted through HKS Dealers. I dont want to take it to the dealer to remap it if i make changes. So i was wondering if its possible to put the SAFC in it if i do make engine upgrades so i can just tune the maps from the SAFC

Well if you tune the maps with the SAFC, then what use is the HKS unit? you could get something that you can adjust yourself, and then just sell the FCON.

It just seems that you wouldnt need both - one or the other, one you adjust, the other an authorized dealer adjusts.
