Riva vs Rotax ECUs
Beside the price what are the major differences or advantages between the Rotax and the Riva ECUs.

my take on it as of now is the rotax makes more power, but the riva has knock control that is needed for high-boost applications. The riva requires dealer activation killing the warranty, the rotax does not. The riva is mapped for 50# inj., the rotax stock injectors.....hope that helps

like 9 said. it mainly comes down to the RIVA is safer to run because it pulls timing when it detects knocking. The Rotax might make slightly better numbers but not worth the safety of the RIVA.

What kinda boost numbers do you gotta be pushing to get any knocking?
