Difference in riva and rotax racing ecu
I'm going to be running the 68 140 le supercharger and was wondering what the main difference in the rr and the riva ecu. I know the rr doesn't have dess key optionor knock sensor

Not much difference, other than that, and the Riva has an 8600 Rev limit, and mapped for 50# injectors. Rotax, can be whatever limit u want.

Timing curve is a little more aggressive on the Rotax VS the Riva too

If it were me, I'd go with the Riva, simply because of the lack the knock sensor option on the RR.
If you got some bad fuel or something the riva unit would pull timing if detonation occurred potentially saving you some trouble.

The Riva One, i have both....
In the Riva you don't have to worry with the injectors, it Works with 48,50 or if the Fuel is Bad the Riva ECU corrects.
Just my opinion
