Here some of the most common questions ask about the FASTBOX.
Q: What is the FAST II system? Is there a FAST I?
A: The FAST II is an add-on fuel and ignition adjustment device for fuel-injected motorcycles, also known as a “piggyback” device. We have developed the FAST II to work in conjunction with our exhaust systems to allow the end user to have a fully-developed complete “kit” of both fuel management and exhaust that works in tandem for optimized performance.
There is a FAST I module as well. It is for fuel map tuning only and does not allow ignition advance adjustment. It is designed for use on single and dual cylinder scooters and was mainly developed for European models. It was not imported into the U.S. and is not currently available through LeoVince USA.
Q: How is the FAST II module different from other systems on the market?
A: The FAST II works very much like the popular aftermarket "piggyback" type systems being used today. Most control fuel adjustment with the same type of strategy, where the FAST II stands out is in the method used to allow for ignition timing adjustment and integrated quickshifter function without the need for additional harnesses/modules. We have also developed it to work seamlessly with our exhaust systems.
The FAST II also features an auto-recovery function. In the rare event of a hardware error, the FAST II allows the stock signals and sensor output to bypass the FAST II and behave as if the unit was not installed. This allows the rider to continue to ride the bike without being stranded and without having to disassemble the bike and disconnect the unit.
Q: Do I need a separate module to adjust ignition timing, or to add a quickshifter, as on other fuel injection controller devices?
A: No, the FAST II already includes fuel and ignition adjustment capability, in one module. By controlling the crankshaft position sensor output signal, we are able to manipulate the ignition advance curve of the bike and allow both advancing and retarding of the ignition timing. This inclusive method also allows us to add a quickshift function by only adding the sensor. There is no need to add an extra harness or another module, even on dual injector per cylinder bikes.
Q: My bike has a top speed/peak power/lower gear power restriction. Will the FAST II eliminate this?
A: It depends on what is causing the power restriction. If your bike has a peak power restriction due to the ignition timing being retarded (like the CBR1000RR for example) then yes, the FAST II will allow you to regain this power as it has the ability to advance the timing to where it should be. If the power loss is due to the secondary butterflies closing (like the 2011 ZX10 or some Suzuki GSX-R models) or by the ride-by-wire, ECU-controlled throttle valve closing (like the R6 and R1) the FAST II cannot eliminate the restriction. If the power loss is gear position based, the FAST II will not affect it either.
Q: Can I use the FAST II with my stock pipe? Can I use it with another brand of aftermarket exhaust?
A: Absolutely. While we will always have maps available for our specific exhaust systems, we usually have some for a stock exhaust as well. It is also possible to use a map for our exhaust systems with another brand if the designs are similar (like a slip-on for example). Besides these provided maps, you can also have your dyno tuner use the included software to make a custom map for you.
Q: I see on the website that you list a lambda eliminator/lambda emulator for my bike. Do I need to order this at the same time?
A: Most likely, yes. The lambda eliminators and emulators (some bikes require an emulator, some an eliminator, depending on the model) allow you to remove the stock O2 sensor and disable the closed loop system. This is important because it allows you to tune the lower RPM range and smaller throttle position openings of the fuel map without interference and adaptation from the stock O2 sensor. If you don't eliminate the O2 sensor, the bike will continue to trim the air/fuel mixture in the closed loop range, and you will not get the optimal performance from your FAST II system.
Q: I have aftermarket rearsets on my bike. Do I still use the sensor that is recommended on the website?
A: Depending on how the linkage is arranged on your rearsets, it's possible you may need the opposite sensor than the one recommend for your bike on the website (push or pull). This can also change depending on if you are using reverse or standard shift pattern. The best thing to do is select the appropriate sensor for the way your shift rod (not the shift lever) is moving when you upshift. You can also watch this video here (insert FAST shift video link)
Q: What version of Windows do I need for the FAST II software?
A: The FAST II Injection software interface should work fine with any Windows-based computer. However, it is highly recommended to use at least Windows XP Service Pack 2 or later. See minimum and recommend requirements below.
Q: Can I use the FAST II software on a Mac OS?
A: Sorry, the FAST II Injection software is only supported on Windows-based operating systems at this time.
