Results of R&D R2 Reflash
I tried my reflashed ecu for the first time and thought some may be interested in the results. My FZS is stage 1ish and still running the stock sc wheel and intercooler. My previous best speed was 73.2 with a lot of rideplate angle and diminished handling. Before this test a few days before I shimmed the plate back down for improved predictability and ran consistently 72.4 and .5. The conditions at the time of the test were similar uper 70's but yesterday a ton of wind.
With the R2 the motor picked up about 200 rpm to 7880-7920 and the boat ran a best of 74.9 with 74.7 runs repeatedly. Without the cross-wind and some more fuel burn off she would have done 75 I'm confident. So it would be safe to say that adding just the R2 is good for 2-3 mph depending on your combination.
In addition to the rpm gain, low end power and response as well as more power through the range was evident. The engine also ran as smoothly as stock with no deadspots or hesitation like you get with the powershot.

did you run the r2 w/o a powershot or with a powershot. Are you monotoring air fuel ratios? What were your rpm's befor te addation of the r2, Thanks Tommy Jordan

Need to get them RPM's up. You're leaving speed on the table.
My AFR's were right on with stock SC wheel and IC.

I want to see what I can get out of some cooling mods, handling mods, and other subtle things + an intercooler now that I have some rpms to play with.
Once we've gotten the most of it on the cheap I'll add a wheel and the pump to match.
It does cavitate now. The R2 adds a lot of low end torque and throttle response. It does still feel faster from a standstill and will jump out of the water like a gpr if you trim up and transfer your weight too fast!

Generally I'm going to try to raise rpm's by adding hp but am going to try a gpr nozzle next time out to see if it helps with r's and speed.
