I'm happy with my terminator x max very good quality. At a reasonable price. 👍 We need versions of this for the coyote and hemi.

I am so excited to get my 5.3 installed and run it with the Holley Terminator X!

[Burndown]

This really is a killer budget friendly stand alone ECU! I really like mine and cant wait to get the race dash for it. Keep up the outstanding work Holley!

I wasn’t planning on changing my ecu setup with my new 6.0, but now I might have to pick this up...

While it’s super cool for tuning there’s plenty it’s missing if your like me, and would rather be able to control everything from one controller or laptop like you can do when tuning a stock ECM .. especially when doing LS swaps you run into issues where you cant use the stock systems for, accessories, without spending a arm and a leg..
This would be crazy cool if they added things like AC, 2 different fan speed controllers, for cooling and condensers, and say fan control for whatever you can come up with, like transmission coolers, or inter coolers, plus a four wire /for 4 O2 sensors for both banks for those wanting to run CATTS..speed sensors for driveshafts and even suspension settings to change shocks and strut settings, be nice to have a plug in for those QA1 settings while on the fly, 😊just take a little motor with a shaft or even a collar to just slide over the knobs on the side of the shocks, and no more climbing under the freaking cars..

I love the whole concept behind the Terminator X and Terminator X Maxx. But a lot use the factory harness and ecu, because we need to pass emissions. You guys come out with a obd2 wire harness or let us know how to interface the obd2 with the Terminator X and I'm sold!

[ryanlott]

Pretty sure you can live tune a stock ecu with hp tuners. Still pretty comprehensive ecu from Holly good work guys

[mythos]

I love how they say its plug and play, yeah with their harness but not with the stock harness. I love the ls engine but shit other manufacturers keep the same damn plug long enough for others to make TRUE plug and play ECMs .

[teknikalvette]

No obd2, nice trick. Some of us need to pass emissions. All the videos I see promote all the features but let's be honest, obd2 is a must.

[rokonmontana]

Any plans for updates for more transmissions like the newer 6l80 6l90's?

[projectgattago]

I have some Terminator X software overview videos on my channel.

[ericwilson]

I've got a question please, is the terminator X capable of doing flex fuel?

[Jmprofessionalimagin]

excellent video, well explained, I just bought the terminator X without the 3.5 display and I bought the 7 ”display, my question is, I can do the first steps as in the 3.5 display that asks you in wizard what injectors you are going to use and what engine do you have and be able to calibrate the tps or not?

[RealityUntold]

Is there a way to re pin the terminator x for a different firing order? Also, could I load a base map for say a different DOHC V8?

[maxgidi]

Can I use my cruise control with this kit??? My vehicle is a 2004 Jeep Wrangler with a 2.4l engine

[hermansmith]

You said big boost but you also said a 2 1/2 bar map sensor so is that all they can do? You can’t use no more than a 2 1/2 bar?

[slickfi]

So the system uses the stock gas pedal and throttle body and tac module?

[dynamicdopamine]

So if I order the big screen to put in my dash to replace the stock gauges (water temp-oil pres-battery volts- and fuel level) in my 4th gen camaro... how will I read "know" how much fuel I have in my tank? Do I have to buy a aftermarket fuel gauge?

[richbororust]

I've been waiting months for my Terminator XMaxx. Holley is not offering any delivery date other than "will ship soon".

[gmiles]

I wanted to put a 5.3 in my boat. Is this all I need to do it?
