As the rather long title says does anybody know what the much more expensive HKS EVC Pro provides over the EVC4.Also could any tech heads explain how the engine knows to supply appropriate fuel/ignition for the different preset boost levels you can set with these machines. Cheers,Deep.

RPM,MAP,O2,AIRFLOW plus other signals,all goes to the ECU which is programmed to give the required fuel and ignition to your engine at a particular rpm and boost.That's the basic function of ECU.

Sorry cant help you on EVC4 or EVC Pro.

Hope this help.

As far as I know the EVC just controls boost levels and doesnt effect fuel/ignition and the Pro just has more settings. I had an EVC 4 on my WRX and it worked fine (i maybe wrong though)
