Irratic Reading From Flex Fuel Sensor Holley Efi
-
Flex Fuel Setup Then I read the instructions on setting up the flex fuel sensor, just have a question. I want to tap into J1 A26 like the directions recommend, but can not assign the sensor to that pivot. I simply get the option to pin information technology to other inputs, but not A26. Can anyone help me out with where to pin the sensor to?
- Pivot A26 is a Sensor +5V Reference Out. You don't "assign" (Pin Map) the sensor voltage or basis pins, they're hard-coded as such. You only assign the sensor signal wire.

Thanks Danny. So based on the directions, it states one wire is +12V switched, one ground, and one to A26. Which ane would go to the ECU to read the sensor values? Distressing for the dumb question, but I'm a little dislocated on this sensor.

It's a +12V sensor (pin #i) & basis (pin #2). The sensor input to the ECU (pin #iii out) needs to also tie into a +5V wire (pin A26), via a 10K Ohm resistor.
http://documents.holley.com/techlibr...r10864rev1.pdf (Holley EFI V4 Software Overview - Department "five.1 Inputs", Pages 12 & 13)No & no. Please read the instructions again.Since I'm but learning this wiring stuff, does the +5V with the resistor provide the +12V source?
Or should I just ignore the A26 & resistor, and connect information technology straight to a switched +12V source?May God's grace bless y'all in the Lord Jesus Christ.

Thanks Danny. Information technology is much clearer now. That +5V A26 is what had me confused. I'll have 2 connections from pin #3; one going to ECU Input, and one through resistor to A26. For the +12V source, I can use one of my 12V Outputs from the ECU right? I appreciate your time helping me empathise this.
- You can, but why waste an ECU Output for powering a sensor? You can too use pivot B20 (EST +12V Output) from the P1B ECU connector. Originally Posted past Aqwk68

I need a footling management today likewise. I decided to wire my flex fuel sensor this morning time and hither'south how it'south wired:
I took pin 1 of the sensor and tied it to B20 (+12V)
Pin 2 is tied to A18 (Footing)
Pivot three is tied to A13 (+5V)I placed a 10K Ohm resistor between A13, and the atomic number 82 to the flex fuel sensor.
I'grand getting an mistake on the dashboard that says Err Low.
I did verify that I have +12V on B20, +5V on A13, and Ground on A18 with the KOEO.93 Notchback, 383ci SBF, Highports, 80mm turbo, custom cam, TH400
- From what I understand, y'all accept this wired incorrect. Y'all need to run the sensor pivot#3 to your HP EFI input, but T in the +5V with resistor wire. -Greg Originally Posted by Rick90lx

Yep, it's wired incorrectly. Read mail #iv. (I shortened this thread, and so information technology makes more sense.)
May God's grace anoint you in the Lord Jesus Christ.

Clear as mud. Take a await at my diagram and tell me where I'm going incorrect. If I accept it plugged in at the sensor, I become a high error in the nuance display. If I unplug from the sensor I become a depression error. I'm at my wits stop hither. Chose a different input, no luck there either.
