HardDrive adds Diag4Bike Diagnostics and Tuning
Launched in Europe in 2011 and available there through distributors such as Zodiac International and Custom Chrome Europe , the Diag4Bike ( D4B ) range of Czech designed and manufactured diagnostic and EFi tuning systems was first seen in the United States at the V-Twin Expo where the company exhibited and gave seminar sessions for two or three years . There has been some distribution of the product line in the U . S . but with Boise , Idaho based HardDrive American V-Twin Products picking the line up expect to see more dealers , including authorized Harley dealers starting to use the D4B program in the coming years . HardDrive ’ s industry veteran V-Twin Product Specialist Gunnar Heinemeyer says that “ even though Diag4Bike is not a common name here in the States , the product is top notch and allows dealers to save the most , make the most and provide the best service to their customers .” The manufacturer of the D4B range is Actia Atal in the Czech Republic - a leading diagnostic manufacturer for automotive companies like Audi and BMW for the last 25 years and , since 2012 , for Harley-Davidson . Some of the most important features of the Diag4Bike diagnostic tool include being able to bleed ABS brakes from the manifold through the computer by front , or rear or in combination ; seeing and clearing current or historical codes ; run a full system ‘ Motorcycle Report ’ and make electrical system checks via the ‘ Toolbox ’ function ; pair new items to the motorcycle - such as radios , speedometers , ECM , TSSM and HFSM modules ; flash a blank ECM ( advance dongle and preregistration is required ); test all actuators such as fuel pump , TPS , turn signals , etc . and adjust the idle and TBW response lag . An advanced dongle and pre-registration is required direct with the manufacturer for some of the functions , such as blank ECU flashing , disarming a security system and replacing or reassigning key fobs ; as is an annual upgrade service , but most of the primary and most often required functions are on-board and readily accessible . All real-time data such as Voltage , AFR , TPS , temperature is more are easy to read , and dealers can improve the professionalism of how they engage with their customers with a customer-specific diagnostic report print out and final tune report with their store logo . In tuning terms , the dongles are married to one motorcycle and will also store the stock calibration for future needs ( the stock MAP can also be saved to a computer ). The USB dongles act like keys to the ECM - they unlock them to allow exportation of the calibration MAP to the screen , make adjustments or choose a MAP and import it back to the bike . This all happens within minutes . The basic dongle ( blue ) is a similar concept to the V & H Fuel Pack but without the external module . It offers limited adjustments of +/ - 20 % in the low , medium and high ranges . Some other functions include acceleration enrichment , spark advance map for each cylinder , on / off closed loop and TBW speed up . This dongle is best for situations of Stage 1 type conditions ( exhaust / slip-ons , air cleaner ) The advanced dongle ( orange ) offers the full range of functions and will open up the MAP for individual cell modifications across all RPM / TPS ranges , as well as offering a choice of performance MAPs for tuning and timing . Other functions , in addition to those offered by the basic dongle , include AFR adjustment for each cylinder , VE maps display with adjustment possibility for each cylinder and idle speed temperature . This dongle is best for

Stage 2 and up type performance needs ( such as exhaust , cams , throttle bodies , big bore , heads ). HardDrive offers a ‘ Shop Pack ’ with four of the advanced dongles for the price of three . Tuning Parameters include but are not limited to RPM limiter , idle and warm-up characteristic , dynamic and temperature enrichments , TBW dynamic control settings , engine displacement , injector flow and more . The Diag4Bike will diagnose model years ‘ 02- ‘ 18 Delphi and ‘ 95- ‘ 01 Marelli ( limited functions ) and tune model years ‘ 06- ‘ 18 . An AFR Monitor is not required , unless needed to create a completely custom MAP calibration ( which will need dyno runs or a very intricate test ride ). The D4B will work with other company ’ s ECUs , such as Thundermax , Daytona Twin Tec , and others .
