EFI Software & ECU Firmware Versions:
EFI SOFTWARE: Click "Help" tab (top toolbar) & "About Holley Terminator X EFI".
ECU FIRMWARE: Click "Sync With ECU" & "Get ECU Info" (Key-on/USB connected).
The latest EFI software & ECU firmware can be downloaded here:

Before updating firmware, ensure the current Global File is saved somewhere, since it will be erased from the ECU.
The EFI (laptop/PC) software, ECU firmware & touchscreen unit must all be version compatible (LINK).

If a regular datalog indicates an "RPM Error" when scrolling through the problem area, then troubleshoot why the crank or
cam sync unit isn't transmitting a signal. Troubleshoot the crank & cam sensors, wiring, reference voltage & ground, reluctor,
alignment, air gap (LINK), radial run-out problems (LINK), etc. Troubleshooting 3-wire Hall-Effect sensors:

The Target Air/Fuel Ratio Table & Base Timing Table can then be properly configured & tuned for any engine. I always suggest taking notes of your current distributor's ignition timing specs/curves beforehand, and then program the Base Timing Table accordingly.

Also, review the datalog and inform us of exactly where in the datalog (time/seconds) the problem occurs.
Datalog & Global Files can be linked to a document hosting website. I use Dropbox.com.
Files can also be "zipped" (compressed zipped folder) & attached directly to a forum post ("Go Advanced" & "Attachments").
Your Config File is in the "Documents", "Holley" folder, "Terminator X" folder, "Global Files" folder (.hefi file).
Your Datalogs are in the "Documents", "Holley" folder, "Terminator X" folder, "Data Logs" folder (.dl file).
Someone will analyze/troubleshoot the problem & offer advice.

Overlay the datalog onto your Config File, and pay special attention to the center paragraph in blue print:

Ensure the Target A/F Ratio table is properly programmed for your engine. Ensure the ECU is "Learning" (Learn Table LINK).
Scroll through the datalog to the problem area. Then look exactly where this happens on the Base Fuel & Timing Tables. Scrutinize:
RPM, MAP, MAT, TPS, CTS, IAC, Target AFR, AFR Left, CL Comp, Ignition Timing, Duty Cycle, Fuel Flow, Fuel Pressure & Battery.

Using the Holley Terminator X EFI software (LINK), look at where the live cursor moves to during this occurrence,
and manually tune that area of the Base Fuel Table (enrich or lean) & Base Timing Table (optimize ignition timing).


I find the most helpful datalog function, is overlaying the datalog on your Config File.
I'm in the habit of using the datalog Overlay feature every time I review a datalog.
Click on "Datalog" (on the top Toolbar), "Activate Overlay", then "Open Data Log".
You can literally "playback" a recorded event, and watch it as it happened on any screen.
Minimize (shrink) the datalog window, and move it to the bottom of any Config File screen.
Then click & scroll anywhere on the datalog, and watch it playback on your Config File (EFI software).
