Why the Holley terminator over the other similar efi kits? Looking at the Holley sniper system myself.
So, a couple of reasons... First the Sniper and Fitech setups put the ECU right there in the throttle body and a lot of people seem to have to go thru extreme measures to keep RFI and EMI from messing with the ECU (Fords especially seem to struggle with this since their distributor is at the wrong end of the engine
The Terminator also has easy connectivity to both the 3.5" handheld display that comes with the unit and USB support to hook to just about any laptop.
The Holley EFI software is awesome. Once you find your way around in it (or better yet, have someone show you around) it is real easy to customize, optimize, and tune the system to meet your needs.
Once I got mine running I had a friend that is very adept at tuning dial into my laptop from his home and he spent about an hour fine tuning the idle portion of the tune. I just sat back and watched as he worked his way thru the software on my computer and did things like start the engine, shut it off, rev it up etc while he watched and tuned from home. It was awesome.
Since then every time I take it out for a drive, when I come back, I download the GCF from the ECU, email it to him, he looks over the learn tables, asks me how it did...makes a few changes, sends me the tune back, I upload it and BAM...the car is better. By the fifth tune or so we are down to fine tuning lugging in the 1200-1600 RPM range, everything else seems spot on.
I had planned to take it to a tuner with a dyno but now I don't think that is necessary, it's that good.
I had an issue where the electric cooling fans were coming on with the key and I had a bit of a low voltage issue. He was able to look at the tune, find the pins where the two fan switch circuits were located...and customize them to only come on when the coolant temps were up to set levels AND the engine RPMs were over 400. BAM, now the fans don't come on until the engine is started. This functionality of the software talking with the divorced ECU makes me very glad I spent the few additional dollars for the Terminator setup.
