Thread: 3.5" TSLCD Terminator to Laptop

  1. #1

    Default 3.5" TSLCD Terminator to Laptop

    I'm working with a 3.5" LCD Terminator Firmware 0.0.1589. Running a 434 ci small block Chevy with street/strip cam. After working out some bugs I got it running really well and drives well too. I'm having an issue with it keeping a steady idle, it surges between 200-1100 RPM, it does eventually level out around my commanded idle of 850 RPM. I've gone through the forum, read everything about the IAC, Idle Adjustments & TPS. I have it set up correctly my IAC is set to "SLOW" with a percentage between 0-5% at hot idle, my TPS is at "0" at idle. I was told it needs to Learn and I have to drive it around 100 miles to really get a good Learn (<-Holley Tech advice). I just recently read to try to stable the idle in Open Loop first which i did and got it spot on. I let the car cool off over night and started it cold this morning, which took about three tries before it stayed running on its own. It ran good and idled fine until about 160°F then it started surging again. I took it for a ride and it drove great with a little surge at idle, during stops it stays running on it's own and levels out at the commanded idle RPM. Now that I have the car running pretty well I don't want to lose the tune it has, so my question is how do I properly save the file? I have the V2 EFI software loaded on my laptop, but I have never used it before. I've watched videos on it, but none have shown how to save the file from the LCD to the Laptop so I can see the tune.

    I want to be able to see the tune it has now and make changes to it on the laptop, then load it back into the LCD. Rather then make a mistake and have to start from scratch, I'd like to ask the question here first even if it may sound dumb to some of you more experienced users. If you could walk me through the process I'd appreciate it. Thank you.

    How to save your Global File to the SD card:
    http://documents.holley.com/199r10751rev1.pdf (Holley 3.5" LCD Touchscreen Instructions - Page 31)
    Insert SD card into laptop, copy & paste the Global File into: "Documents", "Holley" folder, "HEFI V4" folder & "Global Files" folder.
    Then when you open the Holley EFI software on your laptop/computer, it will be listed under "Click here to open selected file."

    I want to be able to see the tune it has now and make changes to it on the laptop, then load it back into the LCD.
    I find it much easier to just use the laptop computer to retrieve & send the Global File to & from the ECU. Read 1st & 2nd paragraphs below.

    Laptop "Online" Communication With ECU:
    Next to the “Toolbox” button, is a button to indicate the following status of ECU/laptop communications.
    Offline: Is shown when the ECU is not powered or the USB cable is not connected.
    USB Link: Is shown when the ECU is powered and USB connectivity is established.
    However, the user has not chosen to select the “Online” mode,
    and the Laptop & ECU are not communicating with each other.
    Changes made at this time on the laptop, are not being updated in the ECU.
    Online: Is shown when the Laptop and ECU are communicating.
    At this point, changes made with the laptop are real-time updated in the ECU.

    • "Get From ECU" & "Send To ECU" - ECU Sync window:
    When you connect a laptop and go "Online" with the ECU, you first want to click "Get From ECU". This updates your laptop with the latest ECU "state of tune". If you click "Send To ECU", you overwrite all the Learning the ECU has performed since the last time that laptop was connected (because you're not sending the latest, up to date values to the ECU). The only time you should click "Send To ECU", is if you're just sending a Global File change to the ECU and you haven't driven the vehicle since the last time the laptop was connected.

    • ECU Date & Time:
    When you go "Online" with the ECU, the option to "Sync ECU Time" (ECU RTC - Real Time Clock) is at the top of the ECU Sync window. Then cycle the ignition key off/on.

    A Terminator ECU is an HP ECU; same ECU, just a different decal. Download the Holley V3/V4 EFI software to your laptop (LINK),
    open the software with the USB cable (LINK/LINK) connected, click on "USB Link" to go "Online" with the ECU, and select "Get From
    ECU", (if there's still a Global Folder/File in it), or "Send To ECU" (if you're selecting a new base calibration to upload into the ECU).

    The EFI (laptop) software, ECU firmware & touchscreen unit (if applicable) must all be V3/V4 compatible (LINK).
    If the touchscreen's GCF Wizard doesn't work, use the laptop EFI software to load the Global File. The V4 EFI software has base
    calibrations available. Open the EFI software & click "Open Global File", then "Base Cals". When using the EFI software, everything
    is done with the laptop. The GCF Wizard or those related files are no longer needed on the 3.5" LCD Touchscreen (TSLCD).

    • Creating, Naming & Saving a Global Folder/File (Global Config Directory):
    You should name your Global File and save it in the EFI software. See below:
    Open the "Help" Contents ("Help" drop down menu), and read "Step-By-Step Beginner's Tuning".
    Or, at least read the "Quick Start Guide": http://documents.holley.com/techlibr...r10546rev1.pdf.
    IF creating a new Global File Name (as opposed to just saving a change in an existing GF), it's much easier to click "File",
    "Save Global File As...", delete the Global File Name shown and just type in the new name you want without any backslash.

    • Emailing Global Folders/Global Files (V4) & Datalogs:
    Your Global File and/or Datalogs can be emailed to yourself or other forum members. Click on their username, "View Profile", "About Me" & "Download vCard" for their email address. When emailing a Global File or Datalog, use your email's 'attachment utility' function and Browse through your computer's "Documents", "Holley", "HEFI" & "Global Folders"/"Global Files" (V4) or "Datalogs". V3 & earlier: Then right click on your Global Folder and Send To "Compressed (Zipped) Folder". Then select the zipped folder and attach it to the email. V4 Global Files & Datalogs (all versions) aren't required to be "zipped"; simply select & attach it to the email. The recipient now has your entire GF or Datalog in one easy step. If it's zipped from email, so download it to your Desktop (or wherever your PC saves it to), and unzip it. Then "Cut & Paste" the GF into "Holley" "HEFI" "Global Folders/Files" directory (located in Documents).
    May God's grace bless you in the Lord Jesus Christ.

    Default Idle Surge

    So I'm still having trouble with this surging at idle.
    434 ci small block Chevy.
    Crane Cam with 230°/240° duration with 112 LSA, solid roller.
    Pro billet distributor with crane ignition.
    No timing control, the Terminator is attached to the tach output of the crane ignition.

    I had it idling perfect last night, I set the open loop until 1200 RPM because I thought that closed loop was the problem, and she ran fine and idled smooth. I let it cool down over night and started it this morning it ran fine and idled smooth until about 160°F, then it started surging and finally died. I checked the 3.5" LCD and it was set for closed loop, so I changed it back to open loop again and made sure it was saved that way. Then started the car and it was still surging. I doubled checked everything, I even put stiffer springs on the distributor advance to make sure the timing was jumping around. I blocked off the IAC port and it still surges. It stays idling, but it surges from like 400 to 1200 RPM. I can not get it to have a steady idle. It's weird because sometimes it will idle steady, but most of the time it surges. Doesn't make any sense as to why it idled fine last night at operating temp, and then this morning when it was cold, but as soon as it starts to warm up it surges. I tried to attach my tune file and datalog, but it won't let me upload them for some reason.


    EDIT: 8:45am 3-29-2018
    So this morning I uploaded V3 EFI software & ECU firmware, copied the tune into V3. Even though my Base Fuel Table was already smooth, I went into the idle region and did a little smoothing. I upped the fuel pressure 2 psi and removed the cover from the IAC. I did a TPS relearn and then started the car. She ran perfect and I let it run for awhile, and it reached 180°F with no problems. I shut it down and will let it cool down and try again later to make sure I'm not going crazy. I'll keep you posted

    So as far as I can tell, the problem is gone. It's raining today, so I can't take this car for a ride. Maybe I can try tomorrow, I sure hope this issue is resolved. Only thing I changed was the EFI software & ECU firmware and adding 2 psi of fuel pressure.
