This is the clearest and the most practical explanation I have ever come across. This clearly shows how an Ohm law's resistance is used for temperature measurement.
This is awesome. I tune Holley EFI systems and the Terminator X ECU does not have the ability to add an extra thermistor. Using a pull-up resistor, I can now easily add an extra temperature sensor as a 5V input.
Brilliant it's like your mind readers! I'm wiring an SR20VE over the coming weeks to an elite 1500 and had seen the note about a pull-up resistor fir the coolant temp. It was the last bit in my mind I wanted to get straight. Now I know what it's all about. Fantastic
yeah I would imagine. Even after watching this I still am a bit confused as to how to install one on a ecu. From the diagram it looks easy, but when you have never done it before.. By the way thanks for pasting the videos you have I have watch a lot of your content and am finding it quite useful.
Master and Slave ecu. PSI/Doosan designed their LPG/NG ECU for an 11L Inline 6 engine, one bank. When they added a slave to run fueling and ignition for the 14.1L V8 and for the second bank they used Diode prior to Shutoff Solenoid as well but in reverse creating a Quantum parallel circuit by reversing direction of diode for Slave side solenoid.. Engineers did not realize this until our conversation as I was curious as to why they chose this route. When i asked them if they was aware. Response from th Engineers was no we did not realize we had created a Quantum Parallel curcuit. He said it just worked on a system not designed for a second bank. Lol SMH.. Yes current would flow through a gates direction diode violating basic laws but not Quantum laws. Was an interesting conversation in 2018. 24v DC circuit FYI
Very helpful. Realised i have some wiring issues with temp sensors i had going to analog inputs. Will have to run an external pull-up resistor for those!
In an aplication where software selectable resistor isn't an option, how would you hardwire it into a wiring harness? Crimping standard THT doesn't seem a very good idea although I've never tried, also the legs are very brittle under vibration so maybe soldering and potting whould be and option.
a lot of people solder them to a dtm 2 pin plug and pot them. otherwise you can get away with just soldering it to the wire and using the cable + heat shrink to support it, usually near the ecu.
I keep scratching my head with the resistor in my wiring as a guy with ocd… Lord Simon says thou shalt not solder, plus the thin strand single core doesnt allow to be crimped into a connector…. I have stopped working with error 404 blue screen of death in my wiring section of the brain.
People just get emotional about being told solder isn't the one tool for every job under the sun and don't notice no one is saying crimping is the one tool for every job either, but we understand your struggles 😂 - Taz.
Help! I have totally been lost after the aircon section! It was lots of scientific talk cancelling itself one word after another…. I will be having a functional aircon in my car too running an Australian standalone ecu… I have been told to use an analog pressure sensor on the refrigerant line to the ecu, here your webinar coincides with what i have, i dont select pull up resistor on in that case. Ac compressor has two wires leading to it so one is ground other is voltage, one of them was connected to a manual rotary switch before because the old tuner decided to be a hack. Ac compressor is also needed to be connected to a relay to power on, and also needs to be connected to an Aux output on the ecu. Well then to tell the compressor to turn on, and both the ecu and compressor to know its time to go to work, the aircon climate control or blower fan motor has to send a voltage to either ecu or the relay that fires the compressor on so which wire goes from the climate control to what now? And the piggyback issue here, if both ecus have pull-ups on same same input or output, then i am assuming we keep pull up switched off on the piggyback unit and dont wire a third resistor to make the client go nuts…. But you cannot turn this off, incase this is a thing like MAF sensor or something related to the life support of the engine….whats the solution here…be careful doesnt cut it.
No being from the country where this video was created I can honestly say it's one of the most annoying and incomprehensible vocal deliveries I've ever heard.

My shit diet and lack of exersize is one of my biggest pull up resistors
😫🤣🤣🤣🤣🤣

Love these golden nugget videos! Much needed info for my trucks wiring needs.
Glad to hear it! Cheers mate =)

Can we get a video in the wiring course on different ways of installing external resistors in a harness, love the vids keep up the good work!
Very helpful. Realised i have some wiring issues with temp sensors i had going to analog inputs. Will have to run an external pull-up resistor for those!
Nice tutorial,
Andre, it is called "Voltage Divider".
Fuckin THANK YOU! this has been driving me insane on haltech.
Such a useful video
Oof thank you! I've been on my fuel level sensor for 2 months.
Is that pull up and pull down resistor , applicable in PLC input and out put???
Possible to create a PWM + output by using a pullup on a PWM - output and how to calculate the resistor value?

I think everytime you tried to make it clearer you made it more complicated.
life is a complicated thing
@@nismofreak33 Yes, and when we get onto pull down resistors ....
👍👍

Why not just explain the resistor and it's purpose
