    Fx sho AFR problems

    So I got a problem getting the right reading on my afr, I got a 2009 Yamaha fx sho with Rivas stage 1 and stage 2 installed, fpr set at 55psi with vacuum connected afr reads at full throttle high 13 low 14, so I adjusted it to 60psi still no change does anyone know what to do?

    Wow man, that's a crazy package that riva threw together to call a stage 2. That E1 wheel just doesn't belong with a boost clamp and just the stock IC upgrade. You should really consider going with a reflashed ECU to get some control of those parts.

    Stock ECU?? That's your problem. There's no way the stock ECU as programmed can deliver anywhere near the fuel you need. Did Riva suggest that list of AM parts or did you come up with that?

    I copied that list from riva's site. They should know better. It's not 2008 anymore. Interesting though that the Riva stage 2 kit isn't listed in the GH store.

    I went with what riva recommended I also spoke to jerry they just missed the stage 2 and will put it up here as well, yes it might be a crazy package, but it does deliver, although I do appreciate everyone comments/concern I still needs some opinions about the afrs
