Tunning & Mapping for EFI
Nowadays with more and more bike switched from carburettor system to Fuel injected system, the tuning world could not be more interesting and exciting. As the advantage of the FI (Fuel Injected) system is much more advanced than the carburettor, the requirement for tuning this highly sophisticated bikes is also increased.
The FI bike give much more Throttle Response, Acceleration, Fuel economy not to mention Low pollution as to conform with the EURO Standard for emission, this thing is hard to achieve with carburetted system. And yet to also achieve that performance gain from fuel injected bike, we need a device that can alter the fuel map so it can meet the requirements of the bike especially for performance use.
 
The principal of Dynojet tuning is simple, use a power commander on your FI Bike, then make a custom perfect map for that bike with the current setup on the dyno to achieve the most maximum performance with your setup. An FI Tuning must consider several factors to make a complete map. First is the Dynamometer machine itself, our 250i dynojet is equipped with state of the art retarder system or eddy current brake, which can manipulate load on your bike, and mimic the load your bike experience on the street. The retarder allow the dyno to map from low rpm to redline with various throttle opening, thing that is impossible to be done on the street or on a dyno without a retarder, other factor is the air temperatur humidity and pressure, which can make a difference in a fuel map made in one place compared to the other.
Example if you make a map on the mountains, your map will be slightly leaner that in the cities with lower altitude, our dyno room is made to simulate this condition with a perfect circulated volume of air that will map your bike exactly like its used on the street for daily use or performance use.  The last factor is of course the tuner itself, Sportisi has tuned hundreds of EFI bikes, ranging from 150cc to a 1600cc Harley Davidson bikes, and lots of sport performance bike in between , this has make us as pioneer and experience in this EFI Tuning industry especially for motorcycles.
You may hear various opinions about Dyno Tuning, the most popular is you dont need a Dyno to tune you FI Bike. well you are so wrong. How can you make a complete perfect map from 1500rpm to 16000 rpm, and from 0% throttle to 100% throttle without proper sensor and equipments ? Ask Dynojet or any other FI Tuners they will answer the same thing . You need to dyno tune your bike if you want to make the fuelling perfect , or the ignition mapping perfect, period.
