Aprilia Motorcycle Specialists.  Performance Parts, Dyno Tuning, and Service for all Makes.

  HP = (Torque x RPM) / 5252     or     Torque = (HP x 5252) / RPM

It is simple math to calculate HP when you measure Torque with a load cell.....
Hint, most dynes do not have a load cell....ours does

To get the the most horsepower and performance out of your engine, AF1 Racing utilizes the latest in dynamometer technology.  We exclusively use the Factory Pro EC997a eddy-current low-inertia dynamometer.   An eddy-current style of dynamometer is far superior to an inertia-style dynamometer (most DynoJet dynes) in terms of its accuracy and capabilities.  An inertia-style dyno is a glorified accelerometer, while an eddy-current dynamometer provides real-world loading of the engine.  Only a true eddy-current style of dynamometer is capable of step-tests, where the eddy-current brake holds the engine at specific RPM data points and measures HP and torque in real-time steady-state.  Testing steady-state, where drum acceleration equals zero, is the only way to get accurate EGA data, True horsepower readings, and real-world loading.  Having the capability to tune steady-state is the only way to accurately tune EFI-equipped motorcycles and flatslide carburetors. 

Look at all that real-time data including integrated 4-gas EGA plots

An inertia style dynamometer measures HP and torque by calculating the acceleration of a heavy drum during a rapid sweep test.  You cannot hold steady-state on an inertia dynamometer (accelerometer) making EFI and flatslide tuning impossible at best.  How does one test highway cruise and part throttle when you have to accelerate the drum just to get a reading?  An eddy-current dynamometer measures rear wheel torque with a load cell while the engine is loaded steady-state at any specific RPM we choose.  Think of it like a giant torque wrench where the brake provides resistance against the force of the tire.  After measuring torque with the load cell on an eddy-current dynamometer, calculating HP is easy. Horsepower is a simple function of torque and RPM.

  Our dynamometer also features a super light roller that is quick to react to load changes and power outputs, which enables us to very precisely tune EFI-equipped bikes, and flatslide carburetors.  Our Factory Pro eddy-current dynamometer is not affected by gearing changes, wheel inertia changes, tires sizes, or tire pressures.  It reads True HP corrected to SAE atmospheric conditions.  It is 0.2 HP accurate every single day, every single run ever done at any Factory Pro tuning center.  We can accurately compare any two sessions any Factory Pro dynamometer has ever done.  No other machine comes close to its repeatability and accuracy.  Expect your HP numbers to be around 12-17% lower with our dynamometer when compared to inertia-type dynes commonly used in magazines and at other shops.  Our machine can run anything from scooters, cruisers, HDs, dirtbikes with knobbies to AMA Superbikes.  Call toll free 877-626-3966 or email us for more info.

 Diagnostic Dynamometer Session with 4-gas EGA     $60                                                      
   For $60, we will perform:

• Full throttle step tests done at specific RPM increments to measure true maximum HP and Torque steady-state with 4-gas EGA. 
• Diagnostic steady-state step tests at various 75%, 50%, 25%, and 10% throttle openings and at various RPM data points with 4-gas EGA.  These tests simulate real-world medium to light engine loads, part throttle cruise, and off-idle responses.
• Idle mixture analysis with 4-gas EGA.  Test will show how to improve idle quality.
• Printouts of data.  All your data is archived with us for comparison to future runs.
• Interpretation of the results and suggestions for improvement

The 4-gas EGA measures %CO, %CO2, HC (ppm), and %O2.  Using a 4-gas EGA not a Lambda (A/F) sensor is the most accurate way of collecting exhaust gas data.  We have the only dynamometer in Central Texas that can do this.  We will analyze the results, and then show you what we can do to improve your throttle response and gain horsepower.  Session takes about 30-45 min, everyday from 4PM-6PM, all day on Saturday, and no appointment necessary.  Call toll free 877-626-3966 or email us for more info.

 Fuel Injection Services       TEKA, PCII, PCIII, PCIIIr, TuneBoy, Kit ECU                                             
     AF1 Racing uses the latest in fuel injection technology to re-map your EFI equipped motorcycle or scooter.  We are leaders in new EFI technology such as TEKA and TuneBoy, custom chip burning, Kit ECU, and Power Commander tuning.

• TEKA:  On all fuel-injected Suzukis, we highly recommend the TEKA fuel injection programmer.  Unplug your PCII, PCIII, or PCIIIr for more power, smoother running, and better starting.  We can make real-time fuel adjustments while running your Suzuki on our dynamometer.  Works on all Suzuki EFI systems found on GSXR 600/ 750/ 1000, SV650, SV1000, TLS, TLR, and Hayabusa.  Cheaper and far superior than buying a Power Commander.  Want to learn more about TEKA? click here and scroll down.  Costs just $199 for everything (no Power Commander anywhere in sight). Hint, this is what the fast CMRA Suzuki racers are using.
   
• PCII, PCIII, PCIIIr, PCIIIusb:   Let us custom map your Power Commander.  We can very precisely tune the Power Commanders with our eddy-current dynamometer and integrated 4-gas EGA (not a Lambda sensor).  Much better than "internet" maps and "auto-tuned" maps.  Get a custom map made for your specific bike.  Price does not include cost of Power Commander.  Tuning costs $250 for PCII, PCIII, PCIIIr, and PCIIIusb.  Add $100 for ignition mapping with PCIIIr.
   
• TuneBoy:  With the TuneBoy EFI system, we can re-map the stock Sagem ECU found on the Aprilia Futura, Aprilia CapoNord, and Triumph fuel-injected motorcycles.  Gains of up to 8hp are typical along with a smoother, crisper throttle response.  Call for an appointment (tuning takes one week), and costs $775 including software key for your bike.  Follow-up tuning costs much less, since the software key is good forever.  Works on all Aprilia Futura, all Aprilia CapoNord, and the following Triumph models:  all Daytona 955i (1999+), Speed Four (2002+), all Speed Triple 955i (1999+), Speed Triple T509 (1997-1998), Sprint RS and ST (1999+), Tiger 855i and 955i (1999+), TT600 (2000-2002).
   
• Factory "Kit" ECU:  We have knowledge and experience with the Honda HRC, Kawasaki Race, and Yamaha Race "Kit" ECUs.  We have the connection cables and Factory software.   Use the ECU the factory race teams use.  Give us a call if you have a CBR600RR, CBR1000RR, ZX6R, ZX636, ZX10R, R6, or R1 as there are better and more accurate tuning options besides a Power Commander.

 Carburetor Dynamometer Services                                                                                                                    
    Utilizing the eddy-current dynamometer we are able to fine tune your carbureted bike or scooter to a degree previously unheard of.  Inertia (acceleration) dynes are unable to hold a steady cruise or simulate driving down the highway.  Using an eddy-current dynamometer is also the only way to accurately tune flatslide carburetors.

• Single cylinder bikes typically run $200-$250 labor plus parts
• Twin cylinder bikes typically run $250-$350 in labor plus parts
• Three and four cylinder bikes typically run $400-$450 in labor plus parts

 Engine Development and Special Projects                                                                                                       
Our eddy-current dynamometer and 4-gas EGA is available for custom tuning projects at the rate of $100/ hr including skilled dyne operator.

We can make your late-model two-stroke exotic fly.  AF1 Racing can very precisely and accurately tune your Aprilia RS50, RS125, RS250, Honda NSR, RS125GP, RS250GP, Yamaha TZ125GP, TZ250GP, Suzuki RGV250, and any other two-stroke GP machines.

Got something mild to wild?? We also have tuning experience with turbochargers, and nitrous systems.

  Below is a Aprilia Tuono Racing on the dynamometer.  The Tuono Racing is a limited edition model (1 of 75) brought to us from Houston, Texas.
