    Yes when they do this

    Shock bolts

    I believe they are the same on the f series trucks, I know the 250 and 350 use that size bolts

    Turbo install

    You have the o-ring on from the turbo pedestal to the intake? It seals the spot where the factory location of the cdr was.

    Shock bolts

    I couldn’t get 1/2” bolts to fit in my shocks, had to get M12 bolts. Don’t worry about how much shank the bolt has as it does nothing when you tighten the bolt and the shock sleeve gets pinched by the shock mount, just make sure the threads come out of the nut a few threads especially if your...

    How to verify if its a long or short pinion 10.25

    If I remember right, I think the long pinion used straps to hold the u-joint as where the short pinion used u-bolts to secure the u-joint.

    fuel gauge test

    Usually pegged past full is an open circuit condition, this can happen if the full switching valve messes up or if both sending units wear out, that’s what happened with my 87 is both senders wore out. This is the resistor piece in the sender that wears out, you can see the missing contact area...

    My arduino gauge project

    I’m using an exhaust back pressure sensor from a 7.3 powerstroke, they go up 40psi and will read vacuum too. Pulled a bunch out of the wreckers, not all of them were good though, 7.3 ones are 1/8” npt, 6.0l and 6.4l are some flare thing and can read pressures up to 75-80psi. The bottom right is...

    My arduino gauge project

    I don’t know a whole lot about running wmo but besides monitoring fuel send temp, do you need to monitor anything else? You could monitor any or all of these, coolant send, coolant return, tank temp, fuel send temp and fuel return temp. I made a quick diagnosis page on my screen a while back of...

    My arduino gauge project

    I’ve been playing around with the data logging and it does work, it puts everything in a text file that’s comma separated, every second it starts a new line and records the values, pretty easy to use. Thanks, post some pics of your pcb when your done. Have you added anything else to the design?

    I have a clunk when I brake

    If everything is tight in the front end than your probably have the notorious huck rivet noise https://www.powerstroke.org/forum/attachments/94-98-7-3l-problem-forum/353081d1414461759-suspension-body-noise-tsb-97-3-10.pdf

    Only one tie rod can be adjusted

    The spring shops around my area won’t sell those add on springs like that, they say they put too much stress on the main leaf causing them to break. My sister bought a f150 that had something like that on it and the springs were all broken, hence how I found out. Personally I wouldn’t run it...

    Only one tie rod can be adjusted

    I highly advise NOT moving the steering wheel as it will throw out the turn signal canceling position and you’ll be lucky to get the steering wheel off again ever! If you only have one adjustment that effects toe then I would be looking at worn out springs, front end bushings and bent steering...

    Glow plug data

    That 400 amps would be absolute best case scenario with no voltage drop from the batteries, wiring or relay. In reality we trade high current for longer heating times. Every beru zd9 I have tested with a low ohms meter reads 0.25 Ohms, 12V/0.25Ohms=48A. As for the factory relay it can...

    Glow plug data

    I posted this a while back but each glow plug draws over 50A each, thats 400+A initial dropping down to about 200A when they are all warm. This is a 7 second run of one glowplug, yellow trace is voltage, blue is current, current starts off over 50A dropping down to about 25A at the end.

    My arduino gauge project

    The program I gave you is designed to read the 2 wire Ford sensors, you will need the circuit below and a Ford sensor for this to work. You only need one "Signal Ground" wire that all your sensors can share, the reason for a separate return ground is to prevent ground current loops from forming...

    @nightrunner84 I think I have the same screen board that you have, try this and see if your screen works LiquidCrystal_I2C lcd(0x27, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE);

    Thanks! Try running this sketch, it will tell you the I2C address of your screen in the serial monitor // -------------------------------------- // i2c_scanner // // Version 1 // This program (or code that looks like it) // can be found in many places. // For example on the Arduino.cc...

    My arduino gauge project

    Try this code, I added the serial monitor to it so make sure yours is set to 9600 or change the code to whatever speed you would like. I also added another lcd pinout in the code, you may have to run an I2C(IIC) scanner program to find the address of your screen if the default 0x20 doesn't work...

    https://bitbucket.org/fmalpartida/new-liquidcrystal/downloads/NewLiquidCrystal_1.5.1.zip You will have to add it by going to sketch-Include Library-Add .ZIP Library... Just to confirm, are you using an LCD with an I2C(IIC) expander board and not just directly connecting the LCD to the...

    My arduino gauge project

    The 2 analog pins are also the IIC bus pins, if you need more analog pins I suggest using a port expander which uses one analog pin and makes it 16 pins https://www.amazon.ca/gp/aw/d/B07K7JF3HX?psc=1&ref=ppx_pop_mob_b_asin_title when I get home I’ll try to figure out which lcd library I used as...

    Front drive axle variations and brakes

    Rotor diameter 87-94 12.56” 95-97 12.95” 99-04 13.03” 05-12 13.66” 13+. 14.29” if you really want bigger brakes look for a 13+ axle use the axle that’s the cheapest for you to use, ball joint vs kingpin doesn’t matter for a tow rig. If you really want a good upgrade I would go with the...

    Here’s my build thread but I’ve been slacking on the updates https://www.oilburners.net/threads/project-crewcab.79692/ As for upgrades I’ve done: 6.4l electro viscous fan Electronic climate control Newer superduty steering wheel I added the airbag system from a f150 so the airbag in the newer...

    Gutless and IP adjustments

    I haven’t had the chance to put the newer fuel system in, the turbo pump is definitely more responsive and more power, as for mileage I’m running my first real tank at the moment so no data yet. I did max out the fuel screw before I put it on but it only moved 3 flats, may try some of Wes’s...

    My arduino gauge project

    The readings bouncing all over the place is from the lack of averaging, lack of a low pass filter into your ADC or could be exactly what your fuel pressure is doing. On my truck the fuel pressure waves around about 1 PSI and a non-dampened mechanical gauge shows the same thing. For the lowpass...

    My arduino gauge project

    Here is a quick simple 4 sensor setup, it reads coolant temperature, oil temperature, transmission temperature and oil pressure. The temperature sensor is the common ford 2 wire temp sensor used on EFI trucks and the Powerstroke engines, these are cheap <$5, they're waterproof and you can get a...
