The VRFI is the V-RodTM version of our proven TCFI fuel injection system for Twin Cam applications.
The
VRFI solves tuning problems with highly modified engines. Competitive
“band-aid” products that interface to the DelphiŽ controller still rely
on speed-density fuel control. Long duration/high overlap camshafts
wreak havoc with manifold pressure - especially at idle and cruise RPM.
Speed-density based fuel control simply can’t cope.
High-end
automotive racing systems use alpha-N (throttle position and RPM based)
fuel control. Alpha-N eliminates any dependence on manifold pressure
and is unaffected by long duration/high overlap camshafts. The VRFI
brings this proven technology to the H-DŽ marketplace.
Unlike
competitive "band-aid" products that only control fuel delivery, the
VRFI allows complete control over all engine functions, including
ignition advance, idle RPM and cold start characteristics. This
facilitates the use of throttle bodies modified for higher airflow.
All
V-RodTM motorcycles use the SAE J1850 data bus for communications
between the engine control module (VRFI), instrument cluster, turn
signal/security module (TSM/TSSM), and diagnostic scan tools. The VRFI
fully supports this new J1850 data bus including the use of the H-DŽ
scan tool to read sensor data and clear diagnostic codes. The VRFI also
has built-in data logging that stores data for the last 15 minutes of
operation. An optional PC link cable and Windows compatible software
allow the use of a laptop PC for programming and data analysis. The PC
link cable plugs into the existing diagnostic connector on the
motorcycle wiring harness.

The VRFI kit includes a wide-band
exhaust gas oxygen (WEGO) sensor interface that allows auto-tuning
during actual on-road riding conditions. The new second generation WEGO
II interface uses a low cost Bosch LSU 4.2 wide-band sensor. The user
programs a table with the desired air/fuel ratios - the system then
does the rest.
The VRFI is intended for modified VRSC engines.
We do not recommend installing the VRFI on stock engines as the unit
will not increase power by itself. We provide setup tables that will
get you up and running. From a practical standpoint, tuning any fuel
injection system requires an exhaust gas analyzer. You can either spend
a lot of time on a dyno with an exhaust sniffer (like the newer Dynojet
units) or you can use our WEGO. With the WEGO, the system will
auto-tune the fuel tables while you ride the bike on the road - you
won't need to spend any time on a dyno. On-road auto-tuning only takes
a few hours and gives much more realistic results that dyno tuning.
