Go into the Go EFI Initial setup then find Reset Learn. Once in that menu, find Reset All Learn, highlight this and push right on the joystick to go to #1, then save that to the ECU by pressing IN on the joystick. Once that is saved, go back to the main menu and then up to the Dashboard and select it.
Can you use nitrous with Fitech?
If the ECU is to be in control of the relay that drives the solenoids, set this accordingly. If the ECU is used with a nitrous system, set this accordingly. If the signal that tells the ECU to enable nitrous is a +12V signal, or a grounding signal, set this value accordingly.
What is idle set mode on Fitech? (video)
Does Fitech need a return line?
You NEED a return regardless with an inline pump fuel system. It comes down to if you are returning from a remote mount regulator or from the built on regulator.
How much fuel pressure does a FiTech need?
That’s because the FiTech System throttle body contains an internal fuel pressure regulator that maintains fuel pressure into the system at a constant 58 or 43 PSI depending on your system.
How do you adjust IAC on FiTech? (video)
What is hanging idle?
Most people say without any mechanical issues, a hanging idle usually means you’re running lean in your idle, or even partial throttle circuit. Found a few sources claiming a hanging idle can also occur when you’re too rich, because of excess unburnt fuel.
How do I turn off PWM on FiTech?
Step 2: go to main menu, scroll down to option 4: Go EFI Initial set-up, click the joystick to enter. Up Enter Down Page 2 Step 3: go under option 1: engine setup. Then, scroll down to option 6 (pump PWM/FCC) and select edit, press clear (CLR) and enter a new value.
How does FiTech fuel injection work?
FiTech Fuel Command Center
The fuel command center is fed by the low pressure fuel pump (either inline electrical or mechanical) used by the carburetor as a lift pump to fill the reservoir with fuel. Inside, the high pressure fuel pump feeds the fuel injectors on the throttle body.
What happens if fuel pressure is too high?
If fuel pressure is too high, your vehicle’s engine could be over fueled, leading to many of the symptoms listed below. Some of these symptoms include your engine running rough, poor fuel economy and black smoke from the exhaust.
What makes more power carb or EFI?
Warren Johnson: Properly tuned, carburetors make more peak power than EFI in a Pro Stock engine. A carb’s pressure differential atomizes the gas a lot better than spraying fuel through an orifice. But EFI has a broader powerband and superior cylinder-to-cylinder fuel distribution.
How much pressure is in a fuel return line?
With a return system, the base pressure is set with the engine off, but the pump running. For a GM, this pressure is usually set to 58psi (factory fuel pressure in the rail). The vacuum/boost referenced regulator will help to change the pressure in the rail based on the pressure in the manifold.
How do I choose a fuel pump? (video)
How do I reset my IAC?
You can reset the idle air control (IAC) valve by turning the car on, putting the car into park, pressing the brake down, then pushing the gas pedal down, counting down about 5 seconds, turning the car off, waiting 10 seconds and start the car again, checking to see if the car is idling properly.
What is the normal idle RPM?
In most of today’s cars, an idle speed of 600 to 1000 RPMs is average. If your car is idling rough, though, it won’t feel smooth. The RPMs will jump up and down, for example, or they’ll fall below 600 RPM (or whatever is typical for your vehicle).
How do you adjust a idle screw?
Set idle speed adjusting screw, clockwise to increase rpm, counter-clockwise to decrease rpm. Idle rpm range should be 950 to 1050 rpms. Adjust idle mixture by turning idle mixture screw slowly clockwise until the engine runs poorly.
Is a hanging idle rich or lean?
Sometimes a lean condition will cause a “hanging” idle that is slow to settle down to set idle speed.
What is throttle cracker?
throttle cracker is what is added to idle airflow at given conditions. Example: Going down the street, let off the gas and at 1600 rpm the car goes into a surge. Chances are your throttle cracker is too high.
Why does my motorcycle stall when idling?
The dreaded stalling issue when the engine is warm is the most common idle problem and it is mostly related to the very lean air/fuel ratio on the modern fuel injected motorcycle engine.
Who owns FiTech injection?
To those hold-outs with their head buried in the sand, we’ve got one thing to say: you better check out FiTech. FiTech, a new American company based in Riverside, California, is the brainchild of Ken Farrell and Jeremy Schmidt.
Which EFI system is best?
Our pick for the best overall aftermarket EFI system is the New Holley Sniper 550511 EFI Kit because it provides a great deal of functionality. For a budget-friendly option, you should consider the FiTech 30021 Go EFI System.
What is Holley EFI? (video)
What are the symptoms of low fuel pressure?
Low fuel pressure can lead to engine misfires, low acceleration, rough idles, and engine stalls. If your check engine light is on and your car has been stalling out, you may have a fuel pump failure.
How do you unstick a fuel pressure regulator? (video)
How do I know if my fuel return line is clogged?
If they do, you’ll notice some pretty disturbing signs. For example, if you have a blocked fuel line, you might end up with smoke inside your vehicle’s interior. This is dangerous, as the smoke contains carbon monoxide, and indicates you’ve got gas flowing back into the tank and leaking into your engine.
Can you Carburate a fuel injected engine?
It is possible to convert your fuel injection into a fuel injection conversion kit that makes the process very easy. In older cars, carburetors are used, but electronic fuel injection (EFI) provides greater fuel efficiency and improved performance.
Is EFI more reliable than carburetor?
When discussing power and performance, there is no arguing that EFI and modern electronic controls are more accurate than carburetion. With EFI, fuel delivery can be tuned to match driver demand. While carburetors can be properly tuned to offer precise fuel delivery, that tune is not able to alter for outside effects.
How much horsepower does fuel injection add?
When looking at pure horsepower, the fuel injection system only delivers about 10 extra horsepower at peak. It is the ability to constantly be tuning the fuel and air intake for each cylinder that benefits the performance.
Which fuel line is the return line?
The vapour-return line normally runs from the fuel pump or the fuel filter to the fuel tank. This vapour-return line is connected to a special outlet in the fuel pump. Any vapour that forms in the fuel pump returns to the fuel tank through this line.
How much fuel pressure should I have?
Fuel pressure for most vehicles should stay in a 5- to 10-psi range. But, techs should make sure to look at the service information for the specifications. Other data PIDs used to regulate the fuel pump include the engine position sensors.
How does a fuel return line work?
How Do Fuel Return Lines Work? This fuel system operates with a fuel pressure regulator that directs the volume of fuel expelled from the intake valves. It uses a fuel pressure regulator to ensure there is no fuel loss through any vacuum effect due to engine power-ups.
How many Lph do you need for 500hp?
|Fuel Pump Free Flow||Carbureted Engine||Fuel Injected Engine|
|40 gph/155 lph||450 hp||400 hp|
|50 gph/190 lph||600 hp||500 hp|
|67 gph/255 lph||750 hp||650 hp|
|90 gph/340 lph||1000 hp||850 hp|
How many LPH is a 1200 hp?
To estimate flow, simply multiply 1,200 horsepower x 0.9 BSFC = 1,080 pounds of projected fuel per hour.
How many gph fuel pump do I need?
A good estimator of volume to power is approximately 10 hp per gallon or 2.64 hp per liter. For example if your pump flows at 50 gph it should be able to support a 500 hp engine (50 x 10 = 500).
What happens if you unplug IAC valve?
If your inactive engine has not changed, you may suspect that it is the IAC. If it works properly, stopping it would cause panic to your inactive engine. Normally, if you turn on your car, the inactive air control valve will increase and decrease the rpms engine slowly.
