I don't know if the Siemens ECU is really any better then the Marelli, if just mapping was needed a 695 with a power commander should make 80 hp. Most of the power gains are from the cylinder heads and cams used on the 696. I would like to see a dyno chart to conferm but I think the 796 hyper is tuned for more midrange, that would explain why the peak power is so close to the 100 cc smaller engine.
That is an interesting point, but my understanding was the 696 heads were nearly identical to the 695's.
Fuel delivery makes a huge difference and the Siemens' ECU may just be better tuned/mapped, I don't know, but they sure squeeze a lot more HP out of that 695 lump for the 696.
I am just saying it would be nice if they brought back an 800ss to do the same.
