sure hope it works better than my returned p.o.s sniper unit .

and if no trans control is required look at this setup . i am going to try one for my 5.3 ls . since i have the full kit now and love it on my 350 L31 vortec engine i figure why not .

edelbrocks tuning software is so much more easy to play with and understand also over the holley stuff for a NON tuning guru .

Edited my original post. I am also swapping in a 4l80e so I will need transmission control
 
The Terminator EFI stuff is Holley's higher-end product line so it should be more reliable system. I do think there's a margin of risk using a product that's new to the market, but sometimes the timing is what it is and you don't have much choice.

it will cost me more but i will do a www.usshift.com for my 4l60-e trans control .

no more holley products for me after the way i was treated .

I was thinking about this lately, whether or not the standalone controller would be worth the additional cost even if you could control the trans with the ECM. I think it depends on how much you want to tinker with programming. I kinda feel like maybe it would have value. Plus, as I've stated numerous times, the Quick4 giving you the ability to program for a doubler/Magnum.
 
also if 1 drops out you still have the other . if all built in 1 then you loose both .

and in the aftermarket i would rather have option 1 of 2 separate units .

Holley just introduced this

What do you all think about this product? I am putting a 2005 5.3L and 4l80e into my 1959 Apache this year.

I am undecided about what to do with the wiring harness.

Thoughts, concerns, suggestions are much appreciated to an LS noob like me

So I know some people work the harness and then get the ecm tuned and turn off certain items and some go for the whole package, how much do those cost compared to this new harness and ecm
 
redone pcm for stock = 1 tune and thats it . if you change anything and or want a different tune = re-flash of the pcm .

aftermarket kits almost all let YOU change stuff and no tune re-flash required .

do you wana pay up for each flash or just pay up a little more and tune your self . that is the question .

There is no paying for each write, atleast with HPtuners. For example my truck is about as costly as it gets. I run an LS3 (Gen IV) managed by a 2002 f-body ecm (Gen III) segment swapped with a 01 1-ton van for tcm controls. This is two vehicles making up one program so it used 4 credits. I've flashed about 100 times.

You have to shop around for the best deals on the mpvi package. But once you have it you also have an amazing scan and datalog tool for all of your vehicles, no credits required. I have no idea how the aftermarket programs work but my pcm also controls all of my engine and transmission fans, and will soon control my fuel cooler. I have the ability for flex fuel control, full transmission control, and pretty much 100% of factory engine control functionality parameters at my fingertips. The datalogging of pids is quick and fairly easy. MPVI2 is even better. I will flash right on the side of the road if there is a change I want to make.

The biggest downside is the learning curve and setup of the programs. Unfortunately Ed, who taught me, has passed away. His package was an excellent value. Not to mention one on one help if needed, whether in your garage or on a dyno.

EFI Live is similar, you basically pay per ECM . Which is retuneable as many times as you want .

The Holley Operating system is pretty bad ass to be honest. I have considered a dominator system for my jet boat

I've always wondered about the Holley setups. A few buddies have had good luck with theirs. My only experience outside of factory is with a GM performance package from early 2000. I'd like to play with one someday. I think the plug and play carb to efi swap thing has alot of potential. Business wise it seems like a no-brainer.

Funny I was going to ask opinions about that.
I have a jet drive boat with a 455 olds thinking about efi, is it worth the effort and money?
 
I got excited yesterday when they release it because I'm running a stock pcm in my turbo s10. Was hoping to consolidate all the electronics: pcm, two step and boost controller. After reading up terminator x only has 4 inputs and 4 outputs. Not enough for a turbo setup, but would work great for a NA setup. I plan on using one for my next build, I have close to 1000 in my custom harness and pcm.

So this is for my aluminum river boat , I still have my Tahiti but that’s big block mopar powered with good old carbs!!

My other boat previously had a 351w in it that had been allowed to freeze and break .

So I found a LQ9 From a Escalade and bolted it in but I don’t have any of the wiring ot ecm .

The Dominator is a very powerful Powertrain management system with tons of options . It’s not really geared for the carb replacement guy though.

my coment was ment for the guy who dont tune stuff . if he had to have it done for him each time .
 
I really wish I didn't see this...

My engine harness is a little hacked up and I have future engine mods I want to do. This would solve it and cost the same and I would get the exact options I want.
 
One thing I just thought of is with the LS factory GM ecm if you have a transfer case that is't electronically shifted you have to ground out a pin to the ECM or it won't shift right in 4 low. I wonder how this system behaves with that.

This all sounds like it's way more than I need. I will most likely keep the engine stock for awhile. So am I better off just getting a new harness and have the PCM re-flashed? My truck won't be hitting the drag strip, it will be hitting the highway though. As in long distance cruising. It will have a bed cap with some gear in the bed. Heaviest thing it will ever tow, would probably just be by 1959 Trotwood Camper which weighs 1700 lbs

Not sure on having the harness reworked, but a new harness that's already reworked are going for 500-600 it seems. Re-flash of the PCM is $200 for most companies
