ps-powersport.com has pretty good information..from what i understand.. the AFE is wired to the ECU.. so it tricks the ECU similar to how E-Manage blue does it.. the difference, or rather, the way it controls close loop is simply using the EST to tell the original ECU to go into open loop...
http://www.ps-powersport.com/support-tech-qa/questions-answers/
it explains it there..
in comparison, i think Dynojet's Power Commander is a more elegant solution for closed loop operation.. considering it sits between the ECU and the Injector..so the ECU cannot undo the Power Commander's fuel trim, and there's no need to trick the car into open loop. -- closed loop offers better fuel economy
EDIT: and while googling, found out our local italian car scene thinks PS products are rubbish..

conclusion? PS Powersport USA is a scam.
