    This is brilliant! I use Haltech myself (on a Ford 2.0 YB Cosworth) but I imagine the same principles apply. Address the root cause, not the symptom. I found this very enlightening. You’d have to think the aftermarket guys simply don’t have the dedicated R&D budget that the OEM’s do. Have you seen the same with other brand stand-alones? And on this, if you are mainly doing street stuff then why bother with stand-alones at all? I know the EECIV can be tuned with the likes of Moates so you aren’t losing any other functionality? I know it’s not as ‘easy’ to tune as the Holley (and others) for various reasons. Keep up the great work man - just subbed 👍

    • @LeechMotorsports

      Thanks Dan. Yes this is one of many reasons we always tel people to tune the stock computer if it’s a street car. Doesn’t even really matter what car or ecu we are talking about. As long as the ecu CAN be tuned, it should be used for street stuff. OEMs do so many things well.

    I’ve setup a 1-D table in the Holley with duty cycle vs rpm on a buddy’s Fox with a 5-speed, heads , cam , vortech, etc. and have eliminated the drivability issues that way.

    • @LeechMotorsports
      @LeechMotorsports  2 роки тому +1

      I’ve been done that path plenty as well. It can work so-so if you actually take the time to sweep target idle across the entire rpm range to determine the appropriate iac duty cycle to maintain each rpm. But that technique still gives no consideration to temperature or changes in target idle speed that you may want to command. Most often, people end up with intermittent runaway rpms.

    Thanks for another great video! Keep them coming.
    People buy the Holley thinking it is mainly plug and play with their canned tunes. They soon realize they can't get the IAC to function without diving into the software. Most likely I will convert to the Holley due to the other features (boost control, datalogging, etc...) not because I think it will provide superior drivability.

    • @LeechMotorsports
      @LeechMotorsports  2 роки тому +2

      There is definitely a path forward with Holley efi for these cars. It just takes some special care with certain aspects of the tune. And if you aren’t already familiar with some of its quirks, you may not immediately find ways to overcome these things. I just got off the phone with a very influential team member at holley, and will do my best to work with them over the coming months. My spirits are lifted.

      The Moates Quarterhorse is still available from coretuning.net via the Quarterhorse package, which includes a usb key license for Binary Editor and EEC Analyzer (the software we use in our videos to tune stock computers). Our friend Danny Kimbler at MF Kustoms is also working on a replacement option (with the documentation/support of Adam Marrer at Core Tuning). No ETA or definitive answer as to whether this will be seen through to completion, but I will say Danny is LEGIT. If anyone can get it done, it's him.

    Matt, I'd like to see Holley come out with more than just a Ford "Linear" option for the IAC drop down. I am using the GM piece with the Accufab adapter in my switch to the Holley X.
    I understand it's not perfect, but I'll take better for now.
    If Holley does make a software revision to the Ford IAC, it will leave those of us running the GM unit in the cold.
    Just thought it was worth mentioning as you talk with Holley.
    My car is at the tuners getting the X installed as a write this, so it's becoming a relevant concern for me.
    I'm switching over from the stock computer with SCT chip, for reference.

  • @bobsmith-st9lq
    @bobsmith-st9lq 2 роки тому +1

    I'm most likely way off. Can a 1d offset table be created for the error %. So IAC offset vs IAC position. Would that keep the valve from never going under 29% and adjusting Idle plate to set idle. This obviously would not change holleys algorithm but maybey it would soften the off throttle between shifts.

    • @LeechMotorsports
      @LeechMotorsports  2 роки тому

      That’s a good thought, but it wouldn’t be possible. I’m this situation, both the input and output of the table would be idle air position. And essentially if we tried to add or remove idle air at a certain duty cycle, it would just do a loop, then make another adjustment instantly based on the new commanded position, and it would just flail around. I actually have done something like this to try to counteract certain ignition timing changes when re entering idle. But the reason that even remotely worked was because the input was based on rpm, not the current commanded spark.

    I sent a link to this video to Mr. Devin Vanderhoof who has a direct line to Holley EFI. He is a fellow youtuber such as yourself although he primarily tunes and wires the very high horse power drag cars. The key is that has a direct line to the Holley EFI engineers because he, along with many others, does beta testing for the Holley tuning software. He is very knowledgeable with regard to the Holley products and if willing could be a great asset to impart your knowledge through to them.
    I so wish you the best luck in promoting some Ford knowledge on to Holley since they are very slow in taking up any interest in Ford products.
