[/quote]devices like VAFC , SAFC, AVC-R and whatever other device rides on top of ur ori ECU...they only manipulate signals from your sensors to trick ur ECU into believing that they are running richer, lower boost...
with standalone engine management units like Haltech and Motec... u have full control of how the engine should run... from ignition & fuel mapping, boost, VTEC, nitrous control to traction control and anti-lag...
a comparison between standalone and piggback is that they have more points per map compared to piggyback...i think SAFC has 6 and Haltec has 500++...
