Sure, you've talked to your engine before. You've probably said some unrepeatable things to it when it decided not to start or ran lousy on a cold morning. With the Pegasus software you can still talk to your engine, but now it will actually listen.
What can you tell it? The Pegasus software lets you completely control your motor's fuel management and ignition characteristics for all types of riding and starting conditions. Getting ready to change the cam or pipes on your bike? With the Pegasus system this is not a problem, because you can easily change the necessary settings with simple configuration settings.
Although the software is powerful, it is still easy to use Only a few settings are needed to get you on the road with significant improvement over your carburetor. In fact, the Pegasus Kit comes to you with the electronic control unit (ECU) loaded with the correct displacement and other settings for your engine, so you may not even have to run our software unless you feel the need to get every bit of performance out of your bike.
Just download the software here and install it on your laptop. Attach your laptop to the serial port on the ECU. Upload the maps in your ECU and begin tweaking.
Once you're done with your changes, you send the maps to ECU and you're ready to ride and see the effects. Repeat until it rides exactly the way you want. The software is also ideal for tuning your bike on a dyno.
With Pegasus 7.0 software you can:
- Download different PFI map files to precisely fit your engine
- Alter fuel and ignition maps depending on your cam, pipes, and riding style
- Change parameters such as engine displacement, rev limit, v-angle, enrichment, starting parameters, and much, much more
- Collect engine data real-time and plot it
- Run closed loop on a dyno to create your own maps
- Diagnose problems
Fuel Map
This picture is an example of a typical "fuel map". To adjust one of the 256 points on the map just drag the point around to change the fuel percentage or use the table editor to see the data in a tabular format. Changes can be sent automatically when you complete a page, or in batch mode after you have finished all of your changes.
