Performance Fuel Injection
Upgrade your carburetor to Fuel Injection for maximum performance
MAD-EFI
Maximum Air Deliver Electronic Fuel Injection systems
for V-twin engines.
Key Benefits
- The only performance EFI system for Harley-Davidson
V-Twin motorcycles
designed from the ground up to maximize your engines performance.
- Simple to tune. The MAD-EFI system does not require the use of a PC
for tuning. Use the included "LCD programmer" box to set all
EFI parameters and monitor the engine.
- Available for Evolution, Twin Cam and Sportster engines
Maximum Air Delivery
(MAD) is required in order to create a high performance engine. Race
bike, big inch custom or a street fighter, it is important that you get MAD
for serious horsepower. We have taken 10 years of MAD technology used in some of
the best marine race engines in the world and applied them to the V-Twin world
of Harley-Davidson.
With a massive throttle plate measuring 2.750" by 2.125", the
intake manifold and ECU used with this EFI is capable of supporting in excess of
200 horsepower in a normally aspirated engine. Maximum power for turbocharged or
supercharged engines are limited only by engine building skills. Poor throttle
response on engines with big cams become a thing of the past with this EFI.
Whether you running an 80CID street-fighter, a 131CID custom cruiser or a 160CID
race bike, your horsepower will be limited by capabilities of the engine
components not the ECU or intake manifold. Click here to view the installation
manual for this EFI. For more information on the MAD V2 EFI project

| MAD EFI Performance Update
Nightrider's 1994 FXDL equipped with a MAD EFI set
an ECTA Land Speed Record of
131.965 MPH in the MPS/PG 2000 class on October 27, 2001. The record
was set on a street bike equipped with un-ported EVO heads, SE-57 cam,
SuperTrapp 2-1 exhaust and Axtell 3 13/16" cylinders.
Not a bad speed for not much more than a stock
engine.

Below are pictures of the new MAD EFI unit for HD V-Twin engines. The
EFI unit has undergone extensive testing on a 97CID EVO engine. Continuous
testing ensures that this EFI meets current and future performance needs for
your V-twin engine. The MAD V2 EFI is now available for serious
performance bikes.
MAD-EFI can also provide the EFI ECU, manifold and other individual
components for race bikes or other custom build applications.
Systems Features:
- Race proven ECU that has been used in automotive and marine environments
for many years.
- Custom design, maximum air delivery intake manifold based on race
proven technology.
- Works with your existing ignition system. The ECU is triggered by the
ignition pulse to the front cylinder. Single fire ignition is required.
- ECU will handle gasoline and methanol fuels with no changes to the the
electronic unit.
- All programming is done through the LCD programmer. Simple trackside setup
and adjustments. No PC is required to program the ECU.
- ECU will control two or four injectors, allowing fine control over fuel
mixtures in high horsepower situations.
Systems Include:
- Harley-Davidson EVO and Twin Cam style intake manifolds with 2.750" x
2.125" inch throttle plate. The intake manifold can be machined to
width for use on longer cylinders.
- ECU - Electronic Control Unit
- LCD programmer
- IAT (intake air temperature) sensor
- CHT (cylinder head temperature) sensor
- Main wiring harness
- Injector harness
- Fuel Mixture trim control, +/ - 50%
- Comprehensive Installation and User Manual (Available
online)
- MAP (manifold absolute pressure) sensors (1,2 or 3 Bar). 1 Bar is used for
normally aspirated engines. 2 or 3 Bar units are used with forced induction
engines with turbochargers or superchargers.
- Bosch Injectors sized to engine power
- Electronic Fuel pump
- TPS (throttle position) sensor
Adjustable Parameters
