Say i bought the Power FC and wanted to install one on my obd2 car? does that completely replace the factory ECU unit? And does it just plug into an obd2 harness? i assume you need to sepecify what model you have? any jumpers required? Will you feel any difference between power fc and your factory ecu? And how does this compare to hondata that keeps the existing ecu right? thanks...

how helpfull would this be if i were to boost later on? avoid engine check light codes? engine would run wil less problems? any info would be greatly appreciated, TIA
