I’ve been working with Fred out at Raptor Performance to get the 2005 Kawasaki Ninja ZX10R more precisely tuned for the modifications and fuel I am using at the track to help overall performance. The initial run brought out 172.5 rear wheel horsepower which is under the stock specification and at 15 years old and 20k miles is pretty darn good.
First off we found out that the Power Commander 3 (PC3) was not connected to the throttle position sensor (TPS) by the previous owner after we were unable to get the throttle to report how much was applied and there was not enough variable in the voltage to report any position. In fact, it was connected to the exhaust flap. Unfortunately, if you don’t follow the specific motorcycle directions this would happen as the correct connection required taking off the airbox and getting to the TPS connector. Problem solved and mishaps averted.
We made three initial passes to get a good understanding of how the 91 octane fuel was being consumed by a zeroed out map for the PC3. We also found a flat line in performance at 8,000 RPMs as the bike was running extremely rich and expelling unspent fuel out of the exhaust.
The first map we tried was the “Completely Stock Bike (updated version of 212-001 based on new production bike)” tune off of DynoJet’s website. This gave us some good groundwork to start adjusting the map at the 100% throttle position. We made three more passes to compare the readings. We were able to identify several variations in the fuel delivery and edge it closer to the 175 RWHP range. The video of the dyno run is below:
Finally, we ended up with 177 RWHP after going through the powerband and making the need adjustments to the Air/Fuel ratio. Below is the video of the finals run:
