You may not have to spend the big $$$$ to join the Delta 400 club. Contact Stewart Taylor at SCS Delta USA. His email is
st.tesystems@gmail.com or call 408-458-6845. They are located in Southern California.
They unlocked my SC Typhoon, uploaded the "latest 961 Cal file" and also included a CAN USB Cable to work with the software, if needed. I haven't needed to. This all cost WAY less than a Delta 400 setup! My idle speed is perfect at start up and low rpm hesitation problems are gone. I have not messed with my bike except for upgraded sensors and relays. My original O2 sensors are still installed.
My SE is a May 2014 build with the Norton Short Open Slip-ons. This ECU work was done last month. So far, so good.
