Rossnemo Racing Superstock Alcohol FZR Shakedown cruise
3rd time out running E85 fuel. Dialing in the vipec ems fuel map. Have it
rerally close, but running it on the rich side to be safe for now. WOT AFR
ratios are from 11.1-11.6. Will close in on the 12.2 target soon.
Accelleration is well, very very good. :) As you can see, water conditions
sucked with wind, waves and lots of other watercraft traffic. Top speed
tuning and testing coming soon on flatwater.
Yamaha FZR SHO 400HP+
A modified SHO stage 3 conversion 2010 model on normal pump gas (93RON)
and no ecu mods done all home baked! put that in ur pipe !
I roughly measured the acceleration speed at 0 to 82 mph at 3 sec ,mods
done to improve handling stock pump but new Riva Racing impeller.
The 1/8th mile in about 6 seconds !
We have done a hundred hours on this ski and
it still has not given any problems ,build to last!
Rossnemo Superstock FZR testing
Testing new 1700 cc bosch compressed natural gas injectors running with E85
fuel. Final Vipec ECM fuel mixture map tuning puts injector duty cycle at
85 percent at WOT. (wide open throttle) with 52 psi fuel pressure. Perfect.
This pass was 91.5 mph in hot tampa summer heat. 06-30-12 Previous pass
was 50-75 rpm faster which equates
to 1 more mph. Previous pass was just a tad leaner on fuel at 12.8 AFR.
This pass was 12.3 AFR. (air fuel ratio). Putting it back to 12.8 of
