hondata is a standalone system. it only uses the oem ecm to basically connect the wiring.
once the Hondata ecm is installed, it takes over 100% from the stock ecm's chip.
and since it's allowing for new values to be programmed, instead of simply altering stock values like a VAFC, it is therefore a standalone ecu.
