Thanks Mr. Tuning Fork
Dude! You are a legend! I tried to understand pull up resistors for quite some time, but you did that in less than a minute! Thanks very much for such great lessons
Yup.. and the worst part is that before you understand them you wonder about their "odd" name. And when you understand them you go "oh, so the name was self explanatory!" :P
This is a fantastic video - the illustrations help explain what Tuning-Fork is discussing, keep it up!
simple but awesome stuff. Thanks
Great timing! :-)
Had to work this one out when you first released a fuel gauge into the IC7
legends. need to do this on a ic7 next week
Glad I now know how to correctly pull the signal into the computer,
Did show how to display on a IC7,
Didn't show how to display fuel level on a factory cluster using a DPO (violet with trace) like how the 1500 can send tacho or speedo,
Can we get the brand/PN's of those fuel level senders?! :)
Useful information that doesn't necessarily apply entirely to a Haltech! That's one reason I'm subbed here, even though I've not got any Haltech products!
What it did highlight, though, is that the value is very "jumpy" when measuring and displaying directly. Does any of the Haltech products offer any "damping" of the signal to slow down the transitions between displayed fuel level - and/or is there any basic electrical circuitry that could be made with common components to smooth out the value?
My first Haltech ECU is being delivered tomorrow! An Elite 2500 for a turbocharged Ford 351W and 4R70W trans. I'm very excited!
Congrats!! Make sure to tag us on the socials so we can see the beast:)
@@haltech Will do! I've been running it on Megasquirt for a while, but I'm interested in experiencing new things (and I want DBW).
Sweet. Was wondering why ground and signal was only letting me get .04 to .24 for 12 to 0 gallons and it jumped everywhere. Thanks!
Wish it was that easy with my platinum sport on a rx7 your interface has improved greatly over the generations
Man your car is nice! :D
@@andersjjensen thank you
Nice Video.
Can you do a video about how to wire in the Alternator and battery control light with a ic-7 dash?
We actually have a full iC-7 install and wiring shoot scheduled for next week, so stay tuned.
@@haltech great😘💪🏼
@@haltech my wallet hurts already 🤣🤣😘😘👍
@@haltech cant wait 😍
If running to ic-7 do you need to run a ground wire from the fuel sender aswell or can we just run the single fuel sender wire from the back of the oem dash?
is it necessary to calibrate if I am about to replace my fuel pump with OEM one?
Do the older Racepak Dashes require a pull up resistor?
Can you set it up for "distance to empty"?
@Haltech if you are using both a nexus and an IC7 dash which would be better to run to?
can that resistor add-on be used on factory clusters that use aftermarket senders? i have an OEM cluster and a VDO sender. the fuel gauge reads the movement the fuel according to the G loads
Hey guys. Which magnetic field read switch style sending unit do you recommend?
hi guys, just about to wire up my fuel level gauge, do I use the fuel level signal conditioner HT-038002 for this? how would I wire this up to the ic7?
What about if my elite 2500 is a plug and play kit , will I still need to do this
Also if I fit sensors to ic7 can my elite ECU see these sensors via can ? This will free up some inputs on ECU thanks
my fuel level sender outputs a resistance reading between 112 ohms - 0 ohms. What would be the ideal pull-up resistor value for wiring direct to an elite series ECU?
is it possible to show dual tank levels ? as i have a 90litre main and a 75 lt reseve in the GQ patrol that i am barra swaooing with haltech ?
How do I get on to the fuel level calibration menu in the new NSP software?
For fuel input to the IC7, you said to wired it to analog input 4 which is pinout 21?
great video.
Question: instead of displaying on a digital dash. Can you use a PWM or other output on the ECU to drive the OEM fuel gauge?
Note: I'm keen to be able to get the ECU to output a signal to my OEM temp gauge so I can reduce wiring clutter in the engine bay. But the process would be the same as outputting to the fuel gauge ;). Just don't know if it can be done.
Regards
Jordan
Should be able to set it up as a generic output and map the fuel level to the frequency
7:40 "The big rod can get stuck..." That statement applies to so many aspects of a guy's life. Scott the Philosopher.
Does it matter it something touches the outside of the capacitive side. Eg, Anti Slosh foam?
While configuring AVI 4 on the IC7 the pull up resistor option says 1000ohm. In the video you say it's 240ohm, is this an error in the video or in the software?
I am encountering the same issue. Did you ever get this resolved?
Can a delay/refresh rate be increased so the level doesn't bounce up and down if driving down bumpy roads?
Some fuel receiver gauges like the ones in old Toyotas have silicone oil built in to dampen and slow down needle movement.
I know its not entirely "Tuning" related, but you should do a video explaining why its bad to run your car on 1/4 tank or less ALL THE TIME.
What about using signal conditioners? Would we still need to wire in the pull up resistor with one of these? Or do they have their own built in?
Just shove a capacitor in parallel to the sensor output/ground and add another resistor to sensor output. There you have signal conditioning
👌🏻
Loving the evolution of your Bedford, you really are mental, lol, cheers bro.
any ideas why won't work on aluminium tank
?? So are you putting voltage to the fuel sender in the fuel???
I'm putting one together and it measures me backwards, what should I do?
How do OE fuel senders work when they dont recognise fuel added to a tank (from a sub tank for example) untill the key is cycled, or in some cases still dont recognise fuel has been added untill you pour 5 or so litres through the filler neck?
China built shit. enuff said.
My fuel level shows only halfway when it has a full fuel tank. And when the fuel tank is half-full, the fuel level will start to show the accurate level of the fuel tank until it's empty. What happened with my fuel level system? Why it could only show halfway but not full?
im in a bit of a problem, i got to install that in the ecu, but i also want it to show in my original panel, how it will work?
Contact our support team via www.haltech.com/support and they'll be happy to lend a hand
So I have a 2000 Impreza with a Elite 1500 and a IC7. If i understand this video. I don't need a fuel level signal conditioner. The car has 2 senders. One for each side of the tank.
Jcar parts number for 240ohm RR0557
You are a legend :) Thank you
@@AllexMurray no problem mate.
Why did I read that as "Full sender level"?
So if I have ic7 and 2500 do I need 240 ohm resistor ?
If the sender is going threw ECU and CAN to ic7 ?
I've put sender into ic7 how do i calibrate in ic7 software?
So convert to raw voltage then get numbers I'm showing correct reading with engine off once engine starts tank level drops from 16L to 8L
What do i do if my input pin on my device has a 10k pullup/pulldown built in and the range of voltage change is tiny? I can't disable it, i tried adding a 10k pulldown on the ground to negate the 10k pullup but that did nothing.
G'day. That sounds like a question for our tech support team. You can reach them at www.haltech.com/contact-us
They'll be happy to help :)
@@haltech I'm an idiot, i put the pull up in the wrong spot lol
Haltech 4tw!!!
Hey haltech 👋 need some help. Trying to setup my IC7 dash in my 01 Z06. Of course they have 2 tanks and 2 sending units... what on earth do I do?!?!?
Hey there, the best thing to do is contact our Tech Support either via phone or on support@haltech.com. One of our tech guys will be able to walk you through the setup.
Hey brah any chance on fuel regulators installation and information

@@haltech thanks!
Send it..
FULL SENDER
So it's just a potential divider basically
What's actually trash is the fact that I paid around $1300 for the IC-7 067012 OBD2 Version. The Fuel Level for my 06+ LS 5.3 Computer has the Fuel Level as a PID in generic data you can see in Global data. My $90 Lufi Xs gauge I got from amazon can read that PID and show Fuel Level with no problems as a Percentage. Your IC-7 CANT! It shows as either Liters/US gallons/CC and doesn't work... Why is it that there is over a $1200 difference and you can't pick global pid data a cheap Chinese OBD2 HUD product can. You guys take pride in your products yet I can't see my fuel level $1300 later. Why should I have to run wires all the way to my sending unit when the level is right in the data already? This seems counter intuitive you sell a product that ignores a very important piece of information to make it work. FIX IT and Update the OBD2 or I'll send it back.

Congratulations!
@@haltech lmao thanks bro lol🤣

Sorry, second. Still - well done:)
