They thought they had a 3-6 months supply and sold them in weeks.

I contacted DD last week and they said that terminator X support should be added by the end of the year.

I am hoping to get my swap on the road before then, but considering the terminator x max cuts my ecu/tcu bill in half I am more than willing to let the 3.5" screen cover gauge duties for the time being.

So If I need a 24X Max kit but with EV6 injectors will I have to order a kit and a separate injector harness?

Yes. Or, if you're handy, you can easily add the EV6 connectors to the harness that comes with it. Or just sell it, since every Holley system uses the same injector harness.

It depends on what throttle body your going to run, and if you want plug and play or if your comfortable moving a couple pins around. If you want plug in plug out of box then you have buy another injector harness harness.

2001 6.0 currently running an LS6 intake and injectors with the 2001 pedal and throttle body. It looks like these do not cover my pedal or throttle body so plans are for a shaved and ported TBSS intake with flex fuel injectors, Caddy pedal and either TBSS or LS2 throttle body. I can change the connectors, I did on my current set up.

In that case we would sell you a 58x harness with the correct injector plug and plug for your TB but then you would have to change a couple wires to convert it to a 24x. It’s easy and Holley even has a video on it. We would be glad to email you a quote for you need, just pm your name and email.

These transmissions have a built in TCU that is located inside the case. My take is that support for them will most likely never happen.

Awesome. Whenever Holley gets around to shipping my stuff, I won't need to wait for that.

You could always run the basic Terminator X system and a standalone 6l80e/6l90e controller. Plenty of people that have done this with a typical standalone harness and GM pcm.

So I am being told that the alternator has to be self excited with this ecu. Does that sound right or is it just to make wiring it easier?

I would not waste one of the 4 precious outputs for the alternator. If you are using a 4 pin alternator, just wire the L terminal to a switched 12+ volts through a resister. There are a million posts about this and Holley even sells a 4 pin pigtail that has the resister built in. I would also suggest adding a wire to the S terminal and running that to wherever your main power distribution point is located.

If you are using a later 2 wire PWM alternator, you can make it work with the Holley, but again, you will waste an output. If I had a 2 wire alternator, I would just get a 4 wire and call it a day.

Thanks for the info, yeah, would like to use those outputs for something else eventually.

Some people have expressed an interest in me making some videos that show the Terminator X software.

Feedback is welcome and encouraged.

Sorry to come in late, but a control+F search for 'ignition' gives you no results on this entire thread. i tried to get the manual to open, but my tablet has an error. so, does this Terminator X system control the ignition timing or not?
i called Holley and was told that the wait was more than an hour. and then it hung up on me. pretty lousy customer Service, Holley!

Monday is by far the worst day to call Holley tech support.

Yes, the Terminator X has timing control.
