    Dragging brakes

    My point is that your statement that unplugging the ABS unit will allow him to determine if it was causing the issue, is false. As I said before, the valves themselves can mechanically stick, or the fittings can leak, or the motor seal can leak. Unplugging the connectors tells him almost nothing.

    Dragging brakes

    There's 2 parts to the abs "unit"...the logic controller/solenoids and the motor/valve body. They are physically separate and the only possible way the electric part of it can be a problem in this case, is if a solenoid is energized enough to pull a pintle to a valve and close off that circuit...

    Dragging brakes

    Master cylinder seal leak is my guess. I've even had a less than 1 yr old new gm master cylinder start leaking air into it. You can test for this by replacing the lines with threaded plugs and applying brake pedal. It should not move. Unplugging the abs controller will not tell you if the abs...

    DEF Fluid Shortage?

    Twins with Twins, Anyone?

    I know what he's using. But whether the Motec or Bosch MS can control shaft speed with fuel fast enough in these cases, I am not sure of. Maybe an electronic gate, properly sized, would be fast enough?

    Twins with Twins, Anyone?

    I feel like it would be pretty tough to even set up a shaft speed limiter in a case like yours where the props break free so quickly. Maybe I'm wrong. It would be great if you could! Good question for the Motec gurus

    Any update to what you guys found?

    Promaxx Heads - Thoughts?

    Kill Devil Diesel is also in the head manufacturing business now and have some outstanding options. But for what you are doing with the truck, stick with a set of stock heads that have had had a good valve job done, good guides put in (bronze), and have been checked for cracks and pressure...

    Need help with lift pump sump, nowhere to install

    I think I see where some confusion started, you thought I was talking about the hot return fuel coming from the Fass and I wasn't, I thought it was just understood by most here that it comes from the high pressure system and is directly related to higher rail pressure command because it is a...

    Need help with lift pump sump, nowhere to install

    It's an easy thing to isolate and figure out the contributions, just separate the pump return from the injector returns and plumb it in after the sensor and compare logs

    Need help with lift pump sump, nowhere to install

    I never stated there was an increase in temp from a lift pump? The increase in fuel pressure at the cp3/cp4 is what generates the heat. There is a slight cooling effect caused after that by the small orifice in the fittings to the rails themselves, but the heat shed there is directly related to...

    You should log a max effort stock motor lml fuel return temp. Also, look at the fuel limiting temperature in the files. Of all of the generations.

    Yeah, the factory fuel temp sensor measures return fuel temp. Log it.

    Need help with lift pump sump, nowhere to install

    I have put a couple dozen Fass pumps on sub 550hp lmls and only 1 truck, a 2016, did not require a sump in order to keep the new Fass pump happy. As far as the older ones, a lot of dyno HP has been made with a big single lift pump and factory pickup. Over 1000hp but unsure how much over. The...

    Need help with lift pump sump, nowhere to install

    What do you mean by "self prime"? I haven't had an issue with filling and priming a Fass system since they switched to their "signature series" pumps. Before that, yes, they cavitated easier and usually needed either a full tank of head pressure or some fuel in the filter to create enough...

    Need help with lift pump sump, nowhere to install

    The LML pickups do not flow as well as the older ones, and the older ones are prone to efficiency losses as well. All but 1 lift pump I've installed in an LML required a sump to keep the pump from cavitating. Call Fass and they'll tell you the same thing.
