So after chatting to a guy on this forum called Chatbovon (who is the translator for the tech guys at API). They agreed to upgrade my fixed performance ECU to the unlimited fully programmable ECU with usb connection & newly translated software. You might think your performance ECU from Kawasaki is good but from what the API tech guys have told me, there is an agreement made that API to gently tone down the power so that they could sell them at Kawasaki & not totally invalidate bike warranties etc etc. The ignition timing is very subtlety retarded to not gain anymore power after 8000rpm (the restricted ECU is way more noticeable, as it completely buggers up the timing after 7,500rpm). This can be tinkered with & an increase in power can be achieved up to the redline & beyond for racing requirements. The ECU also controls the sub-throttle which again has be very slightly tweaked at Kawasaki's request to choke the air supply at high rpm's for warranty reasons again. This software can adjust this as well. Of course all elements of the injectors can be adjusted & fuel MAPS can be tweaked for performance parts that you fit or even for a big bore kit! The tech guys tell me a 330 kit is the max the injectors can handle. But only the basic BB kit will work they say, as performance cams & a ported & gas flowed head will be to much for the injectors. Getting this software working properly should make the TBR juice box completely redundant. I will have a play once i've saved the basic configuration file of the stock performance MAP. My friend has been mapping his Harley ECU for a year now & he will help me get to grips with the fine tuning of my bike & of course Chatbovon will be on hand for tech translating should we need it!! So wish me luck, it's time to suck it & see :?
