Holley Terminator EFI - Install (Update 6-7-18)

[Ly-mo]

I've been toying with the idea of doing this. Looking though Holley's instructions for the kit, it seems like you get PID control at idle, but then you only get one spark advance value for WOT operation, and one for cruise. Is that correct? If you can't calibrate spark advance as a speed/load surface, I'd rather have a vacuum advance distributor...

Maybe ask that on the Holley forum, but I don't think what you are saying is correct. It's user tunable when connected to a laptop with Holleys software.

Read your post again, I think I know what you are saying. There is a setting for timing at idle, cruise, and WOT. if you do nothing else it uses those values for timing. If you connect a computer to the ECU using Holley's software you can put in or take out as much timing as you want anywhere on the grid. You could grenade your motor with timing if you made crazy changes.

Thought I would update this one more time before it ls off into the archives. I'm going on 5 years with this system and it still works great. During that time I had to replace the oxygen sensor but that is the only failure I've had. I was able to reload a good tune that hadn't been corrupted by the bad sensor and drive it until it was replaced so I wasn't stranded. Always keep a good tune that you can reload. Had the Fitech or Sniper been available at the time I bought the Terminator then I would never bought the Terminator. The Terminator is more expensive and more EFI than needed for the Bronco (in my opinion). I started out with the basic settings, not controlling timing, and let it do it's thing. I ran it that way for over 2 years without touching it other than the oxygen sensor. When Holley came out with the dual sync distributor I decided to upgrade. I changed the distributor and upgraded all the software along with adding a 3.5 display. Overall it runs better and performs better since this upgrade, however, it requires some user interface and tuning. I've been tuning on the starting parameters ever since.
