http://documents.holley.com/techlibr...rmwarerev1.pdf (How To Update ECU Firmware)

The instructions (PDF file) & ECU firmware (.eep file, Firmware folder/Documents) are included in the EFI software download.
Go to your "Documents", "Holley" folder, "HEFI V6" folder, "Firmware" folder.
Before updating ECU firmware, ensure the current Global File is saved somewhere, since it will be erased from the ECU.

After updating the EFI software or ECU firmware, I always enter every EFI software screen to verify everything is still correct.
It doesn't take long. Many find Global File discrepancies (especially in Engine & Ignition Parameters) because they didn't look.
The Holley EFI software has a Global File Comparison Tool (C:Drive, Program Files, Holley, V6 EFI), but I choose not to use it:

It's imperative the Engine & Ignition Parameters, Sensors, Idle & Spark ICFs are verified to be correct, before initially starting the engine. If this isn't a DBW application, ensure the DBW ICF isn't included in your Global File (Toolbox, "Remove Individual Config", Drive-By-Wire). A base calibration is what you start with to create your Global File. Five Global File ICFs (software icons) are required to operate the engine: Fuel, Spark, System, Sensor & Idle. Program the correct information into the Engine Parameters, Ignition Parameters, Sensors, Idle & Spark ICFs. http://documents.holley.com/techlibr...librations.pdf (Base Calibrations) http://documents.holley.com/techlibr...r10546rev1.pdf (Quick Start Guide) Which MAP sensor is installed, and which base calibration did you use to create your Global File? Remember, the base calibration you start with, must correspond to the MAP sensor you're using: For example, you can't use a naturally aspirated base calibration for a forced induction engine. This is because the 2,3,5 bar MAP sensor selection only changes the kPa load Y-axis, but not the Base Fuel Table lb/hr values (creating an excessively lean map) or the Base Timing Table degree values (excessively advanced timing map). You must choose a 2,3,5 bar base calibration or reconfigure your existing Global File's Fuel & Timing Tables accordingly. http://forums.holley.com/showthread....4365#post44365 (MAP kPa & RPM Axis Configuration/Tuning Information) http://forums.holley.com/showthread....7531#post77531 (Closed Loop Datalog Tuning - Posts # 2, # 4 & # 6) 2) Ensure the fuel pressure is properly adjusted and the "Actual System Pressure" (Terminator - "Fuel Pres") is accurately entered in Engine Parameters. With TBI (not Sniper) & MPFI, the Actual System Pressure is measured with the FPR vacuum reference hose temporarily disconnected, or key-on/engine-off pump running. The fuel & oil pressure transducers are completely optional. The engine runs the same with or without them. The fuel & oil pressure transducers are used for Data Monitoring, Data Logging and setup Outputs based on fuel & oil pressure. They're "plug & play" into the main harness, and you'll eventually want to use them. And they don't consume any Custom I/O either. This is not to be confused with the "Actual System Pressure" fuel parameter (in Engine Parameters), which must be entered accurately, because the ECU does use this single value for lb/hr calculations. https://www.vaporworx.com/documentat...re-regulators/ (Vacuum/Boost Referenced Fuel Pressure Regulators) http://documents.holley.com/techlibr...owdatarev2.pdf (Fuel Injector Flow & Off Time Data) 3) Ensure the idle speed screw on throttle body, is adjusted to achieve an IAC Position of about 2-5% at hot idle. This explains the idle speed screw/IAC Position % relationship that must be correctly set for proper idle control. Remember to perform another TPS Autoset, whenever you adjust the idle speed screw on the throttle body. In the Idle ICF, the "Target Idle Speed (RPM)" must be programmed to the desired RPM speed at hot idle. Ensure the proper type of Advanced Idle Control is selected in Idle Settings. "Slow" may provide the best idle quality. FYI: Some throttle bodies require a 10% IAC Position at hot idle, to compensate for increased airflow due to further thermal expansion. NOTE: The engine won't start if the throttle (TPS Position) is opened beyond the "Clear Flood TPS" setting (in Engine Parameters). http://forums.holley.com/showthread....neral-IAC-Info (General IAC Information - Read "IAC NOTES") https://forums.holley.com/showthread...e-Tuning-Notes (EFI Idle Tuning Notes) 4) Ensure the ignition timing is fully synchronized with the ECU (idle synchronization and Inductive Delay at higher RPM). If you're cranking the engine (with the injector harness disconnected), sync at 15° or whatever your Cranking Timing is set to. If you're idling the engine (without disconnecting anything), sync at 25° or whatever your idle timing is on your Base Timing Table. Temporarily disable the "Idle Spark" control (in Idle Settings), so the idle timing doesn't fluctuate rapidly when viewed with a timing light. Or use the "Enable Static Timing Set" (in the "Sync With ECU" drop down menu - top Toolbar) for idle sync and adjusting Inductive Delay. http://forums.holley.com/showthread....ing-Holley-EFI (Ignition Timing Synchronization) ↑CNP/COP/DIS & single coil/distributor ignition synchronization verification & troubleshooting information at the end of post # 1.↑ 5) Ensure the crank & cam sync sensor signals are timed correctly. http://forums.holley.com/showthread....m-Sensor-Setup (Crank & Cam Sensor Setup - Not for LSx or most TBI) http://forums.holley.com/showthread....s-amp-Datalogs (Datalog & System Log Information) http://www.masterenginetuner.com/top...all-fails.html (Crank Reference Angle Importance) UPDATE: The new V4+ EFI software allows the Ignition Reference Angle to be changed from −360° to +360° BTDC on # 1 cylinder. This also eliminates the requirement to alter the Firing Order in Ignition Parameters for some unusual applications. 6) Ensure the crank & cam sensors are wired correctly. +5V or +12V & Ground. P1A-A22: Cam Signal Input P1A-A30: Crank Signal Input P1A-A18/A14: Sensor Ground Out/Shield Ground P1A-A26: Sensor +5V Ref Out P1B-B20: EST +12V Out Ensure crank sensor pins A & C (+5V/+12V & GND) aren't reversed. Also, 1x & 4x cam sensors are pinned (A & C) differently at connector. The LS1/LS6 main harnesses are wired for +12V crank & cam sensors. The LS2/LS3/LS7 main harnesses are wired for +5V crank & cam sensors. 58x crank sensors & 4x cam sensors are wired for +5V. 24x crank sensors & 1x cam sensors are wired for +12V.

The +5V crank & cam sensors are powered by the "Sensor +5V Reference Out" pin A26 (P1A ECU Connector). The +12V crank & cam sensors are powered by the "Switched +12V" terminal E (Ignition Harness Connector). Alternatively, you can use pin J1B-B20, which is a clean, ECU regulated +12V for ignition crank & cam sensors (LINK). https://forums.holley.com/showthread...5115#post65115 (58x Crank & 1x Cam - Custom Ignition Parameters) https://forums.holley.com/showthread...6726#post56726 (24x Crank & 1x Cam - Custom Ignition Parameters) http://forums.holley.com/showthread....m-Sensor-Setup (Case 3 & 4: Using a 1 Pulse/Fire Crank Trigger & GM 4x or 1x Cam Sync) The +12V Hall-Effect crank & cam sensors are wired as seen in the Holley EFI Wiring Manual: http://documents.holley.com/techlibr...10555rev17.pdf (Holley EFI Wiring Manual - Figure 11/12, Page 20/21) Look & compare the wiring schematics and the main harness drawings in Section 13, Wiring Appendix: http://documents.holley.com/techlibr...10555rev17.pdf (Holley EFI Wiring Manual - Section 13, Wiring Appendix) Custom Hall-Effect sensors and/or shielded harnesses: 1) The ECU already has the pull-up resistor for sinking output (open collector) sensors inside, so don't add anything. 2) The ECU already has the shield (drain) wire connection/pin grounded inside, so don't ground it at the sensor end. Think of the shield wire as an antenna pointing to the sensor; it's only supposed to be grounded at the ECU end. http://www.newark.com/pdfs/techartic...haWire/USC.pdf (Shielded Wiring - "Drain Wire", Page 2 & 3) http://forums.holley.com/showthread....3598#post53598 (Wiring Additional Sensors - Holley HP & Dominator ECUs) Also, ensure the Switched +12V red/white wire (pink wire - Sniper EFI) is powered in the "Run" and "Crank" key positions. The ignition switch must have a wire that's powered in "run" and "crank" key positions leading to the ignition system. The ignition switch can't start the engine, if there isn't a circuit that's powered in the "Run" and "Crank" key positions. The easiest way to find this wire, is to look at the wiring schematics in a factory shop manual or even a Haynes manual. https://www.msdperformance.com/suppo...s/#EngineRunOn (MSD Troubleshooting - Engine Run-On)

It's quick & easy to move the ignition module ground wire from (cavity) pin D "Chassis Ground" to pin C or G "IPU Ground", where it should be. If you don't have the actual Metri-Pack terminal release tool, a "safety pin" will work. It just needs to be a stiff wire between .030"-.035" in diameter to release the terminal tab. Then reopen (bend) the terminal tab before reinsertion, so it will clip (lock) into the cavity. http://www.whiteproducts.com/removal_tools.shtml (T-6 Micro Terminal Release Pick Tool) Also, don't use (cavity) pin E "Switched +12V" from the 10-pin Ignition Connector, to power an ignition module (or crank & cam sensors), unless you've modified the wiring source to connect from pin B20 - EST 12V Output (P1B ECU Connector).

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. • The EFI (laptop/PC) software, ECU firmware & touchscreen unit must all be version compatible (LINK). If the touchscreen's GCF Wizard doesn't work, use the laptop EFI software to load the Global File. The V6 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" 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: 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. 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. • Emailing Global Files & Datalogs: Your Global File and/or Datalogs can be emailed to yourself or other forum members. When emailing a Global File or Datalog, use your email's attachment utility and Browse through your computer's "Documents", "Holley", "HEFI" & "Global Folders"/"Global Files" or "Datalogs". 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).
