Great video. Just an FYI, the 10k resistor to 5 volts is known as a pull up resistor. I've seen a few videos with guys using 5 watt resistors, a 1/4 watt is pelnty. I use Dale resistors from Digikey.
Didn't realize this video has only been up for 2 weeks - Great explanation! You have a gift for education and speaking. Made it very easy to understand, thanks man! Heading into the garage now with my diagram I created :)
I gotta question bro so I bought a harness from sloppy mechanic that connects to the sensor and into the power tap, would i just need to add the 10k ohm ?
So i just googled it and i see its a external pump im guessing your running a fuel cell with a sump?? Can u run tha magnafuel 4303 thru a factory tank with the original pickup if u mount the pump below the fuel level and close to the tank so it pushes the fuel???
Hi good video! Im having problems with my system. Havent had the car running for awhile. Made some changes like bigger injector and a adjustable pressure regulator. Then updated the computer to v3 firmware and the firmware update went fine until i got to my 7 inch dash. It just wouldnt work with the v3 firmware. Went back to v2 firmware on the display and its working. Anyway after that my flex fuel sensor quite working all together. It worked just fine until i switched to the v3 firmware it went straight to 0 reading and said high err on my laptop when i had it hooked up and 0 on the 7 inch display. I put the car together like 3 years ago and its been setting for awhile but the flex fuel always worked good until the v3 firmware upgrade. Im pretty sure i dont have the 10 k resister on the input wire or the 5 volt wire conneted. Im not running the same flex sensor as yours either. Im going to give this a shot and see if it does anything. Just wondered if the v3 firmware is whats causing the problem now? Thanks
the 55% E content is about right, there was a study done that looked at anti knock index and research octane number of E50 vs E85. Its nearly identical, 101.6 vs 101.5 (yes e50 was 0.1 RON *higher* than E85) AKI was 95.6 vs 95.8 for E50 vs E85 so theoretically speaking, you should be able to make 100% of the power you make on E85 on E50. The two limitations of E50 vs E85 (in my opinion) are this: one, out of the pump the blend stock for non ethanol is raw gasoline without anti knock additives, its roughly 85 octane, with all of the anti knock coming from ethanol. This is a non optimal situation for high performance boosted vehicles as opposed to having E98 blended down to E85, E70, or E50 with a 93 or better octane fuel. 2nd limitation is for those without an intercooler. Alcohol content in the fuel has very high heat of vaporization (HOV) and acts as a secondary intercooler of sorts. While in blends the HOV increases in a non-linear manner and flattens out above E40 as mentioned above with RON and AKI not changing much in e50+ blends, the less alcohol you have in your fuel mix, ultimately the less amount of temperature change you will be able to affect on the cylinder, in a non-intercooled application. Non intercooler applications, again in my opinion will be far more sensitive to blends of sub-E85 than the forced induction applications that have a proper intercooler, simply because of the higher evaporative cooling requirements needed in absence of a IC.
Great video! I'll watch it a few times. This is my first go at efi. Thank you for doing this
@@gregm784 thanks!

Outstanding video. Thank you.
Distribution. 🤔Are you using through the throttle body ? Or port by port?

@@victormagana6476 checkout his wiring diagram I'm not sure on what his harnesses have
@ okay I will, I have a terminator aswell just wanted to ask. Anyway you can pm me some pictures of how you have the wires on the input and outputs?
@victormagana6476 have you confirmed power at connector? It is a fairly straightforward sensor, confirm if inputs are configured correctly also
@@WestcoastWrenchin yes it is I just looked into it and it does have a resistor in it already
Do sensors detect the ethanol percentage accurately always??.
@@klmkt4339 I'd say so, good enough at lesst
@WestcoastWrenchin calibration will become a business opportunity in future
What fuel pump(s) are you running??….ive been thinking of going e-85 on both my supercharged nova and supercharged c10…….ca. 91oct sucks
Magnafuel 4303
@@WestcoastWrenchin just that (1) pump does the job???
So i just googled it and i see its a external pump im guessing your running a fuel cell with a sump?? Can u run tha magnafuel 4303 thru a factory tank with the original pickup if u mount the pump below the fuel level and close to the tank so it pushes the fuel???
@@trentdawg2832 Yes no issues, 860lb per hr fuel today no problem

It for sure has to have the resistor hooked up to 5volt as it's part of the basic principal of operation cheers
Where did you get 12v power from? Can you get the power from any of the pins on the ECU plugs?
I get it now you have a 4 pin power tap and I have an 8 pin. I have a terminator with input/output 8 pin. I don't know if I can program 12v out.
Right off the power tap yea, it's a separate 4 pin connector form the 8 pin yours will have it too
