arley-Davidson has sold lots of Race Tuner FI management packages, and if you stay within the limitations of the listed Screamin’ Eagle parts those Race Tuners work just fine. Change anything in the parts mix to something not carrying a Harley-Davidson part number, however, and you’ve got a tuning problem. Now, the only way to get an accurate and efficient fuel curve is to put that bike on a dyno with an exhaust-gas sniffer and get set for an extensive –and expensive –re-mapping session starting from zero and involving some tedious math.
     Not anymore. Daytona Twin Tec’s Twin Scan 88+ Kit, a neat combination of their Twin Scan 88 Scan Tool and one of their wide-band exhaust gas analyzer WEGO units, allows you to log air/fuel data at all throttle positions and RPMs. The Twin Scan software then automatically analyzes and organizes the data into easy-to-use tables with rows and columns that correspond exactly to the Race Tuner’s input requirements. A process that could conceivably take a full day on a dynamometer has just been reduced to a quick afternoon’s work. The Twin Tec software even highlights the areas needing adjustment, either lean or rich, and all this information can be gathered by simply riding the motorcycle as it would normally be used, or of course on a dynamometer. With the Twin Scan 88+ Kit re-programming a Screamin’ Eagle Race Tuner on a bike using something other than Screamin’ Eagle hardware instantly becomes a lot easier.
     The Twin Scan 88+ Kit works on both Twin Cam engines and the V-Rod. The package includes the Twin Tec Scan Tool; the WEGO unit; a wide-band oxygen sensor; two weld nuts and block-off plugs; and the required software. It’s everything needed to do one motorcycle. The Twin Scan 88+ isn’t limited to just one-time use, either; this is a great tool for a dealership. Unlike the Screamin’ Eagle Race Tuner which marries itself to a particular bike for a one-time installation, the Scan Plus and the WEGO can be transferred from motorcycle to motorcycle. All you’ll need are some extra weld nuts and plugs for the O2 sensor ports. Sound good? If you’ve ever had to re-program a Race Tuner it sure does. The Twin Scan 88+ is available through Drag Specialties, so call your rep today.
