Best tuner for a Harley Davidson Vrod
by Editor on 04/21/17
Fitzgerald Motorsports makes the best exhaust system for the Harley Davidson Vrod and lucky for vrodders is also in a partnership with Daytona Twin Tec a company that makes the best tuner available on the market.
Having this recommendation from the VrodGuru saved me countless hours of research looking into other providers.
Scott recommends using the TCFID Gen 4 Fuel Injection controller. When you put on a exhaust system that allows your engine to breath far more efficiently than stock, it needs more fuel and a this tuner will remap the fuel injectors. (and yes Scott has the maps)
VRFI Gen 4 Fuel Injection Controller for all models of the VRod
By far the best ECM/tuner system for the VRod whether you are doing mild to wild changes this system can do it all. Having installed several systems I can attest this is the ONLY tuner we use for all of our in house big bore builds and even stock motors with nothing more than our Ground Pounder exhaust system. Also great for supercharger and turbo builds with available 300 kPa speed-density software. Here are a list of the features and capabilities.
Quickly auto-tune fuel curves for front and rear cylinders on a dyno or on-road with new WEGO IIID dual channel wide-band oxygen sensor interface.
Fully programmable plug-in replacement for 36 pin Delphi controller.
Robust alpha-N (throttle position and RPM based) fuel control eliminates problems with long duration/high overlap camshafts.
Powerful Windows software for custom programming and data analysis.
Full support for J1850 data bus used for communications with turn signal/security module (TSM/TSSM) and instrument cluster.
Enhanced data logging and diagnostics.
Billet aluminum housing with black anodized finish.
Easy plug-in installation.
Supports all sensors including theft/security module.
