Riva, RR SC with stock ECU
Anyone gone from the Riva to the RR SC with the stock ECU ?
How much more top/acceleration did you see ?
Anyone done any A/F testing yet ?

A/F is fine as long as you run 42# injectors.
I had a reading of 11.7 at WOT and 12.9-13.1 while cruising.
This is with a complete Riva stage 2 kit

What readings did the stock injectors do ?
Was there a top end increase over the riva SC ?

I didn't even try it with stock injectors. It would quickly go lean.
Yes, there was a top end increase.

Jerry can we order them for next batcha nd when are they gonna be hear?
So you trust it with the 42lb. injectors?
Also what was the boost at only 8100rpm's instead of the 8500rpm's?

What is the threshold for A/F anyways for considering too lean.

How come we haven't heard anything out of the people that received them?

So the higher the number the more lean ?
Why did it get lower when it was at WOT ? I would think it would get a little more lean when you went WOT.

Those are results on your wifes ski with the stock ECU or the RR Stock class ECU? If it is a pure stock ECU, has anyone tried it yet with the RR Stock Class ECU yet adn what are the results? Also if people are still worried about the A/F ratios can we use the 50lbs injecters and be safe?
Sounds like a great setup that I will be doing. Also are you running the Rotax through hull exhaust or the Riva one?
