True stand alone Electronic Fuel Injection
Complete stand alone Electronic Fuel Injection can be programed for practically any motor.
This system comes complete with everything needed to run your fuel injected GENIII LS motor
on an airboat or in a Hot Rod. System comes with ECU Electronic control unit, all required
harnesses one harness is for the ignition and one is for the fuel injectors, harnesses plug
into the crank sensor, fuel injectors, throttle position senor, cam sensor, water temp sensor, O2 sensor.
This kit also comes with a high pressure fuel pump capable up to 550HP, fuel pressure regulator,
O2 sensor, relay connection box for easy wiring and installation. We will program this system
for your specific boat application. This ECU is capable of running two maps or different programs
such as one for AV gas and one for cheap gas, or one to ride and one for N20. Can log up to 40
hours of data. You can program endless controls such as a high water temp timing retard, boost control, cold start or even a fuel economy mode for frogging. It offers
a convenient screen that shows crank inputs, cam inputs, water temp, KPA or boost inputs, air
fuel ratios, timing, inlet air temp, RPM’s, oil pressure, voltage it offers endless amounts of
information about your motor and ways to control it! (requires a connected computer or digital dash to be displayed on)
Please, call for current pricing.
Electronic Fuel Injection ECU
This is the computer that we use to control our fuel injection motors. It can be used on many motors as it is a very flexable system. The standard 8 cylinder model for normal aspiration motors like the ones we using on our motors sell for $1700*
Custom Electronic Fuel Injection Harnesses
The standard harness we use on our LS motors sell for $600* Full custom harnesses can be made to order, but will cost more depending on what is needed.
Sensors - Here is a list of the sensors used by the ECU to monitor the motor:
Crank Sensors - Reads the degree of the crank at every moment. Black 24X sensor - $55* and Grey 58X sensor - $60*
Cam Sensors - Reads the cam location for the ECU. Black rear sensor - $42* and the Tan front sensor - $47*
TPS - Throttle Position Sensor - $38*
Water Temp Sensor - Reads the coolant temp from the cylinder head - $36*
MAT - Manifold Air Temp Sensor - $44*
IAC - Idle Air Control
This is how the ECU controls the idle of the motor for cold starts. - $97*
Depending on how much power and what RPM you want to run the motor, will detirmine the size injectors you need for your motor. Sets of 8 injectors start at $300* and go up from there.
Fuel Pressure Regulator
We like to use a Denso regulator for it's reliablity and because it is non-adjustable. These sell for $95*
There are reliable adjustable regulators from Aeromotive. Those sell for $155*
Standard EFI fuel pump
Pump is designed for EFI systems that run a base pressure between 30lbs to 50lbs,
this pump will support up to a 600HP motor. If you run a supercharger or nitrous
we recommend you upgrade to our standard EFI pump. $240*
Platinum EFI fuel pump
This fuel pump is capable of handling an EFI motor up to 800HP this pump will also
handle turbo charged or supercharged motors. Intended for applications with base
fuel pressures between 30lbs and 65lbs this pump will flow over 450lbs per
Super Heavy Duty Fused Relays
These have two fused output posts that can handle up to 70amps each and one of them is switchable through the
relay. These allow you to use the switchable relay post to control the motors electronics and leaves the open
always hot post to wire the console. We turned to these to eleminate the problem of cheap ignition switches that couldn't
handle the currents we needed. Just for testing we wired one to a bulb on the switchable side of one and beat
it on a bench and it never even flashed. We sell it complete with two 50amp fuses and relay pigtail made.$40*
We like the FAST 92mm because it provides enough flow to make power even on are larger packages and this is the only one we have found that was designed well enough that you can adjust the idle without losing a finger or two. $410*
We have found that these do not hold up to the vibrations of props on airboats and can not recommend them for this application. Sorry.
