Note: You should avoid using contaminated fuels in the first place because contaminated fuel causes problems such as faults in the flex fuel sensor. Failure of the Power Control Module (PCM). To connect the Flex Fuel sensor to the car's ECU, you must connect this sensor to one of the ECU's digital pulsed inputs or DPIs with the OUT terminal of the Flex Fuel sensor. From here, take your last length of wire, and connect it to the remaining pink lead (bottom) from the flex fuel sensor. Placing the sensor on the surge tank loop would work fine as well, however during a rapid change in ethanol content (switching from gasoline to E85, for example), the sensor could detect the change before that fuel actually reaches the engine. Whether you choose to crimp your own connectors or use the GM pigtails, the next step is inserting your wire. Please note sensor power and sensor ground wires must be supplied from the ECU, noise and incorrect signals from power and ground outside of the ECU will create an unreliable signal and false data. A real sensor fixes this problem. Note: Verify the connection and functioning of power, ground, and open circuit terminals using a multimeter. Assuming you have a multimeter capable of reading frequency information, back probe your signal wire with the positive probe of your meter. As I mentioned before, your oxygen sensor (some call the lambda sensor) sees 1.

Gm Flex Fuel Sensor Location And Delamination
4T, ran much better than the 87E10 available at most stations. To replace the the Flex Fuel Sensor, a new one will cost you roughly between $400. It may just need several fill ups with flex fuel to fix the problem permanently. Does anybody have experience with a Fuel Composition Snesor? If you have 100% gasoline, then your oxygen sensor is going to tell the computer that the car is running damn near perfectly, resulting in very little fueling change in closed loop operation. Wiring is really the first place where a bit of latitude is given in the install. The e85 does seam to free up a bit of debris from my old tank. Flex Fuel sensors are very much accurate.

Above certain RPM, airflow, and throttle percents the ECM goes in to open loop operation, during this time is uses a multiplier to increase fuel delivery to richer targeted air/fuel ratios. Are you wondering where is the flex fuel sensor located? Works with all major ECU on the market. If a manufacturing problem has occurred, we will investigate the part once it is returned to us, and then check with the manufacturer. Whether you're a do-it-yourselfer or trained auto tech, you'll appreciate the convenience of home or business delivery, or picking up your Flex Fuel Sensor product at the nearest Advance Auto Parts location. The flex fuel sensor uses quick-connect style fuel connections, an incoming fuel connection, and an outgoing fuel connection. The e85 composition is a frequency whist the temp is voltage... or something like that. Be sure to set your baseline ethanol% number to whatever you see on the display after it comes up. The flex fuel sensor measures the fuel alcohol content and sends an electrical signal to the engine control module (ECM) to indicate ethanol percentage.

The bypass function of the Full Flow Sensor Adapter is exceeding the inlet and outlet size of AN10 which maximizes flow at the same time as you get an accurate reading out of the sensor. Most common for mounting is the small flat section in front of the windshield panel. So how does a flex fuel sensor work and what are some common questions? Should make for a super clean look. I put all my fuel stuff over on the RHS of the engine bay away from everything hot and up out of the way. This wire is located under the drivers-side, on the inside of the frame rail, next to the ABS brake modulator. With the GM push-connect style fitting it is very simple to install the new hoses... probably less than 1 minute. There are a few tricks in the tune which I don't plan to detail intimately in this thread that can cause a lot of time wasting and headaches. Pumping the tank out on an NB at dyno and putting E85 in the tank, it took probably 5mins of idling to get the sensor read 70% (it was a 80% blend). This means that you can place a flex fuel sensor on the pressure / feed side of your fuel system without losing flow or having to create a bunch of leak points by plumbing Y and adapter fittings. Known to work with GM ethanol sensors 13577394, 13577379, and 13577429. Welcome to the forum... You may need to have see what the alcohol content reading is...

This install is very similar to the "Basic" install. Don't attempt anything you are not absolutely comfortable with, and always respect common sense principles of safety. The fuel composition sensor is connected with the return fuel line anywhere between the Fuel Pressure Regulator and the Fuel Tank. I have the braided line that others pointed out indicates it can take it. Genuine OEM connector kit for the GM Continental Flex Fuel sensors, compatible with stock terminals and wire. GM sells many "Flex Fuel" vehicles, but only a small percentage have the sensor installed that inspired this whole thread. Instead you will make another feed hose using the Dorman fittings and nylon hose. 8) have no means of handling ethanol contents greater than 10% reliably. With key turned on, the ground wire should be a ground. Next, connect your ground probe to battery ground. Is this true, if so why? The chemical ratio of substances like hydrocarbons, such as methane or ethanol, which is present in the fuel and determines the theoretical air for the fuel's complete combustion, is called the fuel composition. An output frequency between 180 Hz and 190 Hz indicates that the fuel is contaminated.

Terms: Stoich- An ideal air/fuel ratio for the fuel that is being burned. Car is going to be coming back from paint finally so I hope to start assembling it in the next month. There are many many many other sites I have viewed. This is an excellent point to check your work. Before reaching the fuel line, all gasoline flows via the flex fuel sensor. I was thinking about on the passenger side where all the fuel lines are, but those are supply lines. Electronic items are subject to engineering inspection prior to a refund being issued. It would be mounted in the rear of the car soo a little bit of length of fuel line till it gets to the fuel rail would this have a big effect on tuning?. Many factory ECUs and tuning softwares will have the capability to operate Flex Fuel Tuning as well as Holley EFI, Megasquirt, Haltech, Fueltech, AEM and more! The fuel composition sensor has a battery positive circuit, a signal circuit, and a ground circuit. 9% of stations in the USA have "up to" 10% ethanol content in any octane of fuel. It allows you to adapt your hose to directly attach the GM barbed fitting.

Wave frequency corresponds to ethanol content (50-150Hz), and wave pulse width corresponds to temperature(1-5ms). If those are your only two options, I'd stick with installing the sensor on the feed line to the fuel rail. Supplies Required: None additional. Flex fuel sensor, GM ethanol content sensor SE1003. After much speculation and inspection of the tune, I was finally able to determine that the knock-off sensor I was running had a 20Hz offset, causing the car to run excessively rich. All electronic items are carefully tested and inspected prior to sale. Flex Fuel sensors are a 5v reference type of sensor.
Ok thanks for the replies. I think it is safe to assume that most or all members of this forum adding flex fuel are interested in pushing the envelope at least a little. How does the sensor work? I've done some research, and based upon the color schematic of the wire, and what I could find online, this connector appears to be a Fuel Composition Sensor. In this case, expect to see up to a ~10psi pressure drop if multiple pumps are used with a high-powered engine. Alcohol content information is supplied to the ECM from the fuel composition sensor.
Some people choose to run this to a constant 12 volt source such as the battery, but ideally this would go to a switched source. Stainless steel metric hardware. Join Date: Aug 2008. After making your connection, use your multimeter to verify there is 12 volts at key-on on this wire.
