otorcycle electronics are great–until something goes wrong. Those ECUs (electronic control units) that call the shots for a late-model Harley Davidson’s fuel delivery, its timing and for just about everything else that has a wire going to it do a wonderful job. The only trouble is when you do have trouble you’re pretty much at a loss. Figuring out what’s acting up, and why, takes a sophisticated–and expensive–scan tool, and not many shops, and certainly not many riders, have one of those on the shelf.
     Now everyone can. The Twin Scan 88 is the first low-cost scanning tool on the market. It’s made just for late model Harleys, and with a retail price of $149.95 there’s no reason why any shop or serious enthusiast can’t have one. That low price (comparable tools sell for $700 to $2,500) is made possible by using a laptop PC as the display. It provides diagnostic capabilities not found in any other currently available tool, even those expensive ones. The Twin Scan 88 is especially useful for diagnosing hard-to-find intermittent trouble codes, too. It’ll store a 1/2-hour of data before and after the point in time when that the trouble code was set, and this scanner is small enough to be left on the bike for weeks, obviously without the laptop attached.
     The Twin Scan 88 is compatible with all 2001- 2005 Harley fuel injected bikes using the Delphi system (including the V-Rod), and 2003-2005 carbureted bikes with the new 12-pin ignition module. It’ll read and clear diagnostic trouble codes from the
     ECU, turn signal/security module, speedometer and tach. The scan tool offers a full range of capabilities for analyzing and printing out logged data, and there’s even a real-time display of engine data available on an instrument-panel type display. Check with your Drag Specialties rep. These days there isn’t a shop–or a Harley owner–who doesn’t need a scan tool, and at $149.95 the Twin Scan 88 is everyman’s answer.
