    Well... We’re pretty much stuck at the moment. The only thing left that we can do with the GT350 is send the injectors off to get flow tested before pulling the engine for further diagnosing. Hopefully we find something soon! 🤞 Have you gotten your entries in to win the FRS? Head to www.dls.store right now and every $1 spent is 1 entry in to win!

      That car should start up better than that something is not right check the plugs they always tell you something, then check the simple things first

      Bad ground in the wiring harness. Only occurs in the engine harmonics at certain rpm.

      If you have a knock sensor i would turn it off. It could be a harmonic issue.

      Direct wire the pumps and if you have a Hobbs switch bypass it. Might fix it

    Yes the breakup was happening to my foxbody at abt 3k what we did was some timing spark plugs and plug wires and it works now

    is the timing right

  • FORD_ASSET_TECH
    FORD_ASSET_TECH

    Check the output shaft speed sensor/output shaft flange nut. There is a TSB stating the nut could be loose allowing the output shaft tone ring to move in relation to the output shaft causing an erroneous signal. It could be just at the particular RPM range? It sounds like a misfire too me - Almost like spark blowout. How tight is the gap on the plugs?

    Understand through out some ideas here just because I had breaking up issues with my Jeep and it ended up being the ground that went from the head to the firewall you've already checked everything else that I would have checked. Is it possible that it could be a throttle body issue?

  • Mikey M.

    I don’t think this is the problem, but could it be the fuel rail. Maybe it restricting flow to injectors or the injectors are pulling hard and cause the far injector to have a inconsistent fueling to back pistons.

  • Grimm’s Garage
    Grimm’s Garage

    If the Injector balance test goes good it has to be weak spark due to the new tune or possibly the fuel volume through the inlet from pump. If it’s the same company/tuner then it might have reached that bottle neck in the system. Maybe the valves are mistimed/floating or the tune is not set up for the ms of delay needed in increase of rpm.

  • Grimm’s Garage
    Grimm’s Garage

    Could it possibly be the cam lockout reading different on the tune until 6k? If the engine is dripping off like that seems like a mechanical issue if before hand the afr is steady until that rpm. Just a question I figured I ask. Maybe the chains are stretching a degree or two or the tuning is set up with non-optimal degrees of timing after that rpm.

  • Aj Satterwhite

    Never messed with high horse power cars, but couldnt be a vaccum leak caused by crank pressure? Which is why your only seeing it at certain rpm ranges

    Could be something with the turbo compressor approaching the surge line momentarily. Maybe ramping up boost a bit differently would cure it? MAF volume may be something to watch over boost pressure.

    Bud, Stang mode has been having problems with his 2020 Shelby but see the comments on this episode of yours. I've seen the comments and there saying it's a electrical issue, as far as ground. But please get with Stang mode, make a episode where your both channels come together. But look at the comments, there REALLY TRYING to help you. God bless you and hope more episodes to come. From me: hope you get that new 2020 Shelby and convert it to a manual 😁

    A drop in fuel pressure would indicate a flow issue to the injectors, a weird varience to AFR from a external working wideband indicates a fuel supply issue, if there isn't a surge in boost or a reduction in boost at the RPM range, then that won't be affecting AFR's. If we move up the line you could have a valve issue, either not letting enough fuel, or letting too much fuel in, but considering its a new engine and that would display as different issues too. At a certain RPM more voltage is required to allow spark plugs, injectors etc to fire, so what could be happening is your ground to power might not be 1:1, and there could be too much or too little resistance at that point thats causing the electronics to not be able to do what it's supposed to do. I would recommend to check all ground wires, battery terminals, check all injector and fuel pump wiring for continuity to rule out whether those are faulty, however what I recommend to everyone when I speak to them about engine works and electronic stuff is to when you've made massive changes, like more electronics etc, is to increase the gauage of the wiring used on both the power and ground wires. Its a tedious job, but considering the change in the tune did nothing and its happening now, I would suggest you might have some burnt out wires, either on the injector, fuel pump wiring side, could also be wiring to the coil packs. I believe strongly its a WIRING and ELECTRICAL issue rather than a mechanical issue. RPM based usually indicates an electrical problem due to interference in the wiring circuit.

    Better yet if you just did spark plugs check the pig tails make sure they ground or signal wire on 1 or more has not pushed out. Sorry for double comments

    Yea that sound like your injectors are hitting max duty cylce. But they realistically have some trash. If not i would check valves. See if they are leaking by bad enough that can't hold pressure at that rpm range. Or your coil pack harness is losing ground from ecu/ cam sync at that rpm range. Lol

    My buddy had the same thing going on with his sti high rpm little stutters. Turn out it was his pump relays. They would spark out high rpms and lean it out and would keep the same boost. But who knows. I would look at coil packs.

    I am wondering if this car came from a state with specific performance car cutooffs, AKA the tattletale box they had on Vettes that logs RPM, torque and speed loggin it and flashing it to a file... They may have a auto engine ignition cutoff set on performance cars to disable the engine when it hits a specific set RPM in this case at 6,000 RPM its disabling or distorting the signal to the coil

    Seems like a crank sensor issue/ cam sensor issue to me. The way it cranks sounds odd and like its taking longer than expected trying to find out where everything is. I've seen a couple cars with bad cps run fine till high rpm when the gap between the sensor and the reluctor become too far apart and the vibrations cause it to rattle and not pick up the signal as good. Lund should be able to see this in the log file. If nothing else i would try changing crank and cam sensors and see if the issue persists.

    Could it be the fuel rails. I can’t remember if those were upgraded and it could be the third pump creating a weird flow pattern that affects it for a split second.
