My Story
I am retired after spending a lifetime designing large electrical systems worldwide. My passion for motorcycles started at the age of 11 when I got my first minibike. Of course I had to teardown and rebuild the mighty 3.5HP engine weekly. Carburetor and Ignition systems were a fascination to me. I repeated this process of riding, wrenching, optimizing with my Kawasaki trail bike, Triumph Bonniville, Suzuki race bike, Yamaha dirt bike, Harley Davidson (Panhead, Shovelhead, Evo, Twin Cam), and now Indian TS111.
I learned tuning on carburetors (re-jetting) and ignition point systems. Always thought there should be a better way...then I bough my first fuel injected bike, a Harley Davidson Twin Cam. I learned tuning by changing out the Delphi ECU with the ThunderMax ECU with wideband sensors. After taking that system to its fullness, I found TTS Mastertune software for the Delphi ECU. Unfortunately my 2005 bike did not have narrowband o2 sensors so I bought a takeoff harness from a 2006 bike with its Delphi ECU and converted my 2005 to a bike with narrowband closed-loop fuel injected system.
The TTS Master Tune had an application called VTune which allows the user to tune in their bike by placing a large portion of the AFR table into closed-loop operation (up to 85% load....90 kPa). I was amazed how well one could tune in their bike with this system. At this time I also started to use a local Dynojet 250i dyno to develop tunes for the Harley Davidson, especially performance packages. To tune client's bikes, I used Dynojet Power Commander III or the TTS Mastertune. Just depended on their request.
After taking time out with fuel injection systems (bought and rebuilt a '76 FXE Shovelhead), I purchased my current ride, 2016 Indian Roadmaster. At about this time there was rumor that Dynojet was developing a flash tuner for the Polaris fuel injection system named Power Vision CX. I wrote a letter to Dynojet sales office offering to be a Beta tester. To my excitement, they sent me a unit and software to start testing on.
The absolute ease and power of the PVCX and Dynojet Power Core Software Suite blew me away. I could write equations that performed powerful math on the tune using actual logs from the operation of the bike to correct all the tables within the tune. For the first time since 2005, I could manipulate and correct the tables the way I wanted to correct them.
So I decided that others should experience the ease and power of tuning their bikes themselves. Hence this blog and YouTube videos.
