Greetings John,

I have installed one of these units in my NSR MC21 bike. The HRM III TT-F3. The Transformation of my bike is far better than any expectations i had.
I have a stock mc21 engine with HRC carbs kit and JHA exhausts and when i went to the dyno i had 68hp. I 've installed the ecu about a year ago and so far i haven't got any kind of problems with it. The Bike runs fantastic.
