    If you wanted to rebuild a 7.3 idi, increase it's performance w/o a turbo, what would you do?

    The best I ever could get was mid 10mpg in the summer and 8mpg in the winter, drove like a grandpa made no difference, this was with a zf5, 4.10 and 35” tires, tried 3 different IP’s and made no difference, tried timing from 6-12degrees didn’t help either. In the end I found my expectations had...

    If you wanted to rebuild a 7.3 idi, increase it's performance w/o a turbo, what would you do?

    Turbo also helps with elevation, if I remember right, every 1000ft is -3% in power, if your at 5000ft that’s -15% right of the bat, just some food for thought. Not sure what your hoping for power and your expectation but this is a 45 year old engine technology, they don’t have good power but...

    7.3idi turbo vs 7.3idi

    You also need the turbo engine balancer and flywheel/flexplate as they are weighted differently than the NA engine.

    7.3 idi throttle position sensor question

    The reason I say don’t use the battery is because we don’t know if the ground to the TCM is good, if it’s bad and the TCM is “floating” then any measurements will be off, measure right at the sensor using it’s dedicated ground back to the TCM will help rule out odd readings. Grey/red is the...

    7.3 idi throttle position sensor question

    Before you can fix anything you need to double check the vref voltage going to the sensor and make sure its right, if it’s truly 7.2v you need to figure out why (most likely bad TECA/TCM) it’s so high, you can throw as many TPS sensors at it, adjust it till you throw the thing across the yard...

    7.3 idi throttle position sensor question

    Are you 100% sure you got 7.2v WOT? The tps is only fed 5v from the TECA/TCM, if your getting 7.2v then the 5v vref is way out of spec and could be a bad TECA/TCM, also the BARO sensor is probably bad also as it runs off the same 5v vref as the tps sensor does

    Arduino Glow-plug Controller, Build & Walk-through

    Just FYI, your going to smoke that INA226 on first power up, if you want to try a Hall effect sensor at least look at ACS772ECB-200, you’ll still be out of range on it but it won’t melt in front of your eyes.

    Arduino Glow-plug Controller, Build & Walk-through

    I’m not sure exactly how you plan to use the ACS712 to measure glowplug current, it’s way too weak to even read one glowplug nevertheless 8, even using 8 ACS712 still won’t work. Look up VN7007AHTR It’s a high side driver that has a ton of protections, current sense, can be driven from the...

    Arduino Glow-plug Controller, Build & Walk-through

    You have a great project idea but you need to back up a few steps and solve some major hurdles that you haven’t mentioned yet. What are you going to do to run the arduino in a vehicle? You can’t just hookup the Vin to the fuse box and expect it to live very long with load dumps from the...

    Can our IDIs use a Powerstroke tach?

    Going off memory here but any powerstroke clusters with a tach will say turbo diesel under the tach

    Can’t win for nothing electrical edition

    At least the fence wire has some rust protection! I’ve repaired a lot of boat trailer lights and 90%+ the ring terminal attached to the plastic light housing screw has rotted off and everything in the light is rotted away. Ford did do alright with the chassis harness grounding, they ran a...

    Passenger side head not getting oil

    If you have the heads off you can still use the starter and see what your oil pressure is, I know on my engine I can get 40-50psi of oil pressure just from the starter turning the engine over. Your engine having no heads would make it a lot easier for the starter to turn it and you can watch the...

    Glow plug amp draw

    Cold glowplugs have a 0.25 ohm resistance, each plug draws over 50A-60A(battery voltage drop dependent) each, they drop quickly to about 30A in 3 or so seconds. So initial switch on your up around 400A draw, dropping to about half after several seconds. These plugs draw a lot more than people...

    Anyone have any Sterling 10.25/10.5 Build Experience?

    I usually try for 8-10 thou, I can’t remember spec off hand but I think it’s 6-15 thou

    Anyone have any Sterling 10.25/10.5 Build Experience?

    The inner pinion bearing changed when they went to the 10.5, if your putting 10.5 gears in a 10.25 housing you have to use the 10.5 inner pinion bearing in the 10.25 housing.

    An power steering lines?

    I highly recommend NOT using hydraulic hoses or any metal braided lines from the pump to hydroboost as they couple engine noise and pump noise to the firewall, been there done it, sucks having that loud ps wine when turning or breaking.

    Arduino Gauges

    For some reason I didn't get notified about your earlier post, maybe because you tagged me I got notified this time?;Poke I'm using the u8x8 library, when you call u8x8.setFont(u8x8_font_8x13_1x2_r); the "r" at the end sets the reduced front set, "f" uses the full set and "n" only has numbers...

    Arduino Gauges

    Been busy with a new job so I haven’t been working on it a ton but I have found that the I2C (IIC) interface is the bottle neck running 9 displays, I have the I2C interface running at 1Mhz instead of 400Khz which helps and I’m only updating displays that have changed in valve which helps a lot...

    Arduino Gauges

    I figured I should start my own thread for this, here’s my version of an arduino and gauges. I wanted something that would go into the factory location and replace those 4 useless gauges with something that is more accurate. These little 0.96” OLED displays fit nicely, have great light output...

    Flex plate size

    The flexplates look the same, will bolt up the same but the factory turbo has more counter weight then the non turbo, if you run a non turbo plate on a turbo engine, the engine will be out of balance and shake badly.

    Sensor data for a android app I'm making

    Your best bet is to ditch all the factory gauges and put useful sensors in, not sure what your using for a micro but an esp32 would give you Bluetooth and wifi and a ton of processing power if you need it. Here’s a little something I’ve been playing with to replace the 4 useless gauges with 9...

    ardunio madness

    My setup started was this, worked pretty good but wasn’t very pretty. Then I made this to clean it up, it’s a touch screen so I can easily switch between different pages to see more info but it’s a bit small. This is the latest thing I’m working on that will replace the instrument cluster, 7”...

    ardunio madness

    @1mouse3 what I did for sensors was go to a wrecking yard and pull a bunch off of trucks, most will be good with the odd bad one. The 7.3l EBP sensor is a 1/8”npt, I’m using one for boost and fuel pressure as it will show vacuum(more about this later), I have a EOP sensor from some Chevy truck...
