Riva ECU and NEW C-kit. DO I need a FPR?
Guys do I need to get a FPR with the RIva ecu and new C-kit?
Also since 18p.s.i is the safe limit for stock 93oct gas. Is it safe to say that I may aswell just stay with the new C-kit and 15p.s.i since I do not want to go race fuel and stay a little safe?

So the Riva ECU only works with about 13-14 lbs of boost until it needs some help?

Right! I wouldn't push it more than 14 PSI without the rising rate regulator.

Will the c-kit work with the FPR/Rotax ecu and 38's?---or should I use 42's?
Trying to find a deal on an ecu/valvetrain kit----not sure which ecu I'll end up with. I've heard good things about both.
This new FPR setup seems to be the ticket----been doing it for years with the mustangs/camaros on a boosted app.

The Riva ECU is mapped for 50# injectors so you set the rising rates base pressure at 60. Don't try to run more pressure than that.
So said the C kit will work with RR ECU and 38's, but i would feel more comfortable running the 42's and i would measure the AFR just to be sure.
I am in love with this rising rate regulator. The US made brand should be available in the next 2 to 3 weeks
