Dobeck's engineering staff was dismayed by the decision, but the Dynojet 100 exclusively measured surplus power available to accelerate the vehicle's mass-no more, no less-and that was true even if the modification was a low-inertia flywheel or lightweight wheels. And that was that: For once and forever, the power of everything else in the world would be relative to the '85 Yamaha VMax and a fudged imaginary number. /rebates/2fproduct2f400-9622fdynojet-tuner-kit&. This allows the use of 87 octane fuel with the better throttle response, slight power increase, and reduced exhaust popping. It retains the Dynojet rev limit increase, fueling, and throttle maps. Not sure why but I guess its not that uncommon with the dynojet tuner. This tune has the timing map that only has a one degree advance over stock at higher rpm and throttle settings. Dynojet Jet Kits increase power and smoothness throughout the entire rev range, while maintaining optimum fuel economy. Im happy with the setup but the tuner has lost the tunes twice now and needed them reloaded. Im still waiting on the intake/catch can to become available. Always a pragmatist, Dobeck finally ordered his Chief Engineer to doctor the math so that the Dynojet 100 measured 120 hp for a stock VMax. Ive got AA pre air cleaner piping, charge tube, BOV, exhaust, clutching and level 1-5 tunes.movable weights is important, and dynjot appears to have that covered, so that’s good. if you luck into senior staff it’s better, but. Inconsistent and contradictory advice, etc. Meanwhile, existing aftermarket torque-cell engine dynamometers delivered numbers that clustered around 120. I do know I’ve found dynojet tech support to be lacking. The VMax had 145 advertised factory horsepower, which was far above the raw 90hp number spit out by the formula. Dynojet's final number-fudge was arbitrarily based on a number from the most powerful road-going motorcycle of the time, the '85 1,200cc Yamaha VMax. ![]()
